00:00The following is a conversation with Anne Drouin, writer, producer, director, and one

00:06of the most important and impactful communicators of science in our time.

00:10She co wrote the 1980 science documentary series Cosmos hosted by Carl Sagan, whom she

00:16married in 1981 and her love for whom, with the help of NASA, was recorded as brainwaves

00:24on a golden record along with other things our civilization has to offer and launched

00:29into space on the Voyager 1 and Voyager 2 spacecraft that are now, 42 years later, still

00:36active, reaching out farther into deep space than any human made object ever has.

00:43This was a profound and beautiful decision Anne made as the creative director of NASA's

00:48Voyager Interstellar Message Project.

00:51In 2014 she went on to create the second season of Cosmos, called Cosmos A Space Time Odyssey,

00:58in 2020 the new third season called Cosmos Possible Worlds, which is being released this

01:05upcoming Monday, March 9th.

01:07It is hosted, once again, by the fun and the brilliant Neil deGrasse Tyson.

01:14Carl Sagan, Anne Drouin, and Cosmos have inspired millions of scientists and curious minds across

01:21several generations by revealing the magic, the power, the beauty of science.

01:27I am one such curious mind, and if you listened to this podcast, you may know that Elon Musk

01:33is as well.

01:35He graciously agreed to read Carl Sagan's words about the pale blue dot in my second

01:40conversation with him.

01:42If you listened, there was an interesting and inspiring twist at the end.

01:48This is the Artificial Intelligence Podcast, if you enjoy it, subscribe on YouTube, give

01:53it 5 stars on Apple Podcast, support it on Patreon, or connect with me on Twitter at

01:58Lex Friedman, spelled F R I D M A N.

02:02As usual, I'll do one or two minutes of ads now and never any ads in the middle that

02:06can break the flow of the conversation.

02:08I hope that works for you and doesn't hurt the listening experience.

02:13This show is presented by Cash App, the number one finance app in the App Store.

02:18When you get it, use code LEX PODCAST.

02:21Cash App lets you send money to friends, buy Bitcoin, and invest in the stock market with

02:26as little as $1.

02:28Since Cash App allows you to send and receive money digitally, peer to peer, and security

02:34in all digital transactions is very important, let me mention the PCI data security standard

02:39that Cash App is compliant with.

02:41I'm a big fan of standards for safety and security.

02:45PCI DSS is a good example of that, where a bunch of competitors got together and agreed

02:50that there needs to be a global standard around the security of transactions.

02:55Now we just need to do the same for autonomous vehicles and artificial intelligence systems

02:59in general.

03:01So again, if you get Cash App from the App Store or Google Play, and use the code LEX

03:06PODCAST, you get $10, and Cash App will also donate $10 to FIRST, one of my favorite organizations

03:13that is helping to advance robotics and STEM education for young people around the world.

03:19And now, here's my conversation with Anne Drouin.

03:24What is the role of science in our society?

03:26Well, I think of what Einstein said when he opened the 1939 New York World's Fair.

03:35He said, if science is ever to fulfill its mission the way art has done, it must penetrate.

03:46Its inner meaning must penetrate the consciousness of everyone.

03:53And so for me, especially in a civilization dependent on high technology and science,

04:00one that aspires to be democratic, it's critical that the public, as informed decision makers,

04:12understand the values and the methods and the rules of science.

04:18So you think about what you just mentioned, the values and the methods and the rules and

04:24maybe the technology that science produces, but what about sort of the beauty, the mystery

04:30of science?

04:31Well, you've touched on what I think is for me, that's how my way into science is that

04:37for me, it's much more spiritually uplifting.

04:42The revelations of science, the collective revelations of really countless generations

04:50of searchers and the little tiny bit we know about reality is the greatest joy for me because

04:58I think that it relates to the idea of love.

05:02What is love that is based on illusion about the other?

05:07That's not love.

05:08Love is seeing, unflinching the other and accepting with all your heart.

05:16And to me, knowing the universe as it is, or the little bit that we're able to understand

05:21at this point is the purest kind of love.

05:25And therefore, you know, how can our philosophy, our religion, if it's rootless in nature,

05:32how can it really be true?

05:35I just don't understand.

05:36So I think you need science to get a sense of the real romance of life and the great

05:47experience of being awake in the cosmos.

05:50So the fact that we know so little, the humbling nature of that, and you kind of connect love

05:59to that, but isn't it also, isn't it scary?

06:04Why is it so inspiring, do you think?

06:06Why is it so beautiful that we know so little?

06:10Well, first of all, as Socrates thought, you know, knowing that you know little is knowing,

06:16really knowing something, knowing more than others.

06:19And it's that voice whispering in our heads, you know, you might be wrong, which I think

06:27is not only it's really healthy because we're so imperfect, we're human, of course, but

06:32also, you know, love to me is the feeling that you always want to go deeper, get closer.

06:38You can't get enough of it.

06:41You can't get close enough, deep enough.

06:44So and that's what science is always saying is science is never simply content with its

06:50understanding of any aspect of nature.

06:53It's always saying it's always finding that even smaller cosmos beneath.

06:59So I think the two are very much parallel.

07:04So you said that love is not an illusion.

07:08No, it's not.

07:09What is love?

07:12What is love is, is knowing, for me, love is, is knowing something deeply and still

07:21being completely gratified by it, you know, and wanting to know more.

07:28So what is love?

07:30What is loving someone, a person, let's say deeply is not idealizing them, not putting

07:40some kind of subjective projection on them, but knowing them as they are.

07:48And so for me, for me, the only aperture to that knowing about nature, the universe is

07:55science because it has that error correcting mechanism that most of the stuff that we do

08:00doesn't have.

08:01You know, you could say the Bill of Rights is kind of an error correcting mechanism,

08:05which is one of the things I really appreciate about the society in which I live to the extent

08:12that it's upheld and we keep faith with it and the same with science.

08:17It's like we will give you the highest rewards we have for proving us wrong about something.

08:25It's genius.

08:27That's why, that's why in only 400 years since Galileo's first look through a telescope,

08:36we could get from this really dim, vague, this vague apprehension of another world to

08:46sending our eyes and our senses there or even to going beyond.

08:52So it is, it is, it delivers the goods like nothing else, you know, it really, it delivers

08:59the goods because it's always, it's always self aware of its fallibility.

09:06So on that topic, I'd like to ask your opinion and a feeling I have that I'm not sure what

09:12to do with, which is the, the skeptical aspect of science.

09:18So the modern skeptics community and just in general, certain scientists, many scientists,

09:24maybe most scientists that apply the scientific method are kind of rigorous in that application.

09:30And they, it feels like sometimes miss out some of the ideas outside the reaches, just

09:35slightly outside of the reach of science.

09:37And they don't dare to sort of dream or think of revolutionary ideas that others will call

09:43crazy in this particular moment.

09:45So how do you think about the skeptical aspect of science that is really good at sort of

09:50keeping us in check, keeping us humble, but, but at the same time, sort of the kind of

09:55dreams that you and Carl Sagan have inspired in the world, it kind of shuts it down sometimes

10:01a little bit.

10:02Yeah.

10:03I mean, I think it's up to the individual, but for me, you know, I was so ridiculously

10:08fortunate in that I, my tutorial in science, because I'm not a scientist and I wasn't trained

10:14in science, was 20 years of days and nights with Carl Sagan.

10:20And the wonder, I think the reason Carl remains so beloved, well, I think there are many reasons,

10:26but at the root of it is the fact that his skepticism was never at the cost of his wonder

10:33and his wonder was never at the cost of his skepticism.

10:38So he couldn't fool himself into believing something he wanted to believe because it

10:42made him feel good at the other.

10:45But on the other hand, he recognized that what science, what nature is, it's really,

10:52it's good enough, you know, it's way better than our fantasies.

10:57And so if you, if you're that kind of person who loves happiness, loves life and your eyes

11:04are wide open and you read everything you can get your hands on and you spend years

11:09studying what is known so far about the universe, then you have that capacity, a really infinite

11:18capacity to be alive, but all, and also at the same time to be very rigorous about what

11:27you're willing to believe.

11:28For Carl, I don't think he ever felt that his skepticism cost him anything because again,

11:36it comes back to love.

11:37He wanted to know what Nietzsche really was like, not to inflict his, you know, preconceived

11:44notions on what he wanted it to be.

11:46So you can't go wrong because it doesn't, you know, I mean, you know, I think the pale

11:51blue dot is the, is a perfect example of this, of his massive achievement is to say, okay,

12:01or the Voyager record is another example is here we have this mission, our first reconnaissance

12:07of the outer solar system.

12:09Well, how can we make it a mission in which we absolutely squeeze every drop of consciousness

12:19and understanding from it?

12:21We don't have to be scientists and then be human beings.

12:25I think that's the tragedy of Western civilization is that it's, you know, when it's one of its

12:33greatest gifts has been science and yet at the same time, it believing that we are the

12:42children of a disappointed father, a tyrant who puts us in a maximum security prison and

12:50calls it paradise, who looks at us, who watches us every moment and hates us for being our

12:57human selves, you know?

13:00And then most of all, what is our great sin?

13:03It's partaking of the tree of knowledge, which is our greatest gift as humans.

13:09This pattern recognition, this ability to see things and then synthesize them and jump

13:17to conclusions about them and test those conclusions.

13:21So I think the reason that in literature, in movies, the scientist is a figure of alienation,

13:31a figure, you know, oh, you see these biopics about scientists and yeah, he might've been

13:37great, but you know, he was missing in ship.

13:41You know, he was a lousy husband.

13:44He lacked, you know, the kind of spiritual understanding that maybe, you know, his wife

13:52had and it's always in the end and they come around, but to me, that's a false dichotomy

13:59that we are, you know, to the extent that we are aware of our surroundings and understand

14:05them, which is what science makes it possible for us to do, we're even more alive.

14:10So you mentioned a million awesome things there, let's even just, can you tell me about

14:16the Voyager one and two spacecraft and the interstellar message project and that whole

14:22just fascinating world leading up to.

14:24One of my favorite subjects, I love talking about it.

14:27I'll never get over it.

14:29I'll never be able to really wrap my head around the reality of it, the truth of it.

14:35What is it first of all?

14:36What's the Voyager spacecraft?

14:37Okay, so Voyagers one and two were our first reconnaissance mission of what was then considered

14:44the outer solar system and it was a gift of gravity.

14:49The idea that swinging around these worlds gives you a gravitational assist, which ultimately

14:58will send you out of the solar system to wander the Milky Way galaxy for one to five billion

15:06years.

15:08So Voyager gave us our first close up look of Jupiter, Saturn, Uranus, Neptune.

15:19It discovered new moons.

15:21It discovered volcanoes on Io.

15:28Its achievements are astonishing.

15:31And remember, this is technology from the early to mid 1970s.

15:37And it's still active.

15:38And it's still active.

15:39We talked to Voyager a few days ago.

15:42We talked to it, in fact, a year ago, I think it was.

15:46We needed to slightly change the attitude of the spacecraft.

15:50And so we fired up its thrusters for the first time since 1987.

15:55Did they work?

15:57Instantly.

15:58It was as if you had left your car in the garage in 1987.

16:04And you put the key in the ignition because you use keys then in the ignition and it turned

16:09over the first time you stepped on the gas.

16:12And so that's the genius of the engineering of Voyager.

16:17And Carl was one of the key participants in imagining what its mission would be because

16:26it was a gift actually of the fact that every 175 years, plus or minus, there is an alignment

16:35of the worlds.

16:36And so you could send two spacecraft to these other worlds and photograph them and use your

16:44mass spectrometer and all the other devices on Voyager to really explore these worlds.

16:54And it's the farthest spacecraft, it's the farthest human creation away from us today.

17:00Voyager 1.

17:01Voyager 1.

17:02These two spacecraft not only gave us our first close up look at hundreds of moons and

17:08planets, these four giant planets, but also it told us the shape of the solar system as

17:17it moves through the galaxy because there were two of them going in different directions

§02Transcript · 17:23–34:11

17:23and they finally, and they arrived at a place called the heliopause, which is where the

17:28wind from the sun, the solar wind dies down and the interstellar medium begins.

17:35And both Voyagers were the first spacecraft that we had that could tell us when that happened.

17:41So it's a consummate, I think it's the greatest scientific achievement of the 20th century.

17:50And engineering in some sense.

17:51Engineering, I mean really, you know, Voyager is doing this on less energy than you have

17:59in your toaster, something like 11 Watts.

18:04So okay, but because of this gravitational assist, both Voyagers were destined, as I

18:10say, to, first of all, they were supposed to function for a dozen years and now it's

18:1642 years since launch and we're still talking to them.

18:20So that's amazing.

18:22But prior to launch, almost a year, eight, nine months prior to launch, it was decided

18:31that since Frank Drake and Carl Sagan and Linda Solzman Sagan had created something

18:36called the Pioneer 10 Plaque for the Pioneer spacecraft that preceded Voyager, which was

18:44kind of like a license plate for the planet Earth, you know, man and a woman, hands up,

18:50you know, very, very basic, but very effective.

18:55And it captured the imagination of people all over the world.

18:59And so NASA turned to Frank and to Carl and said, we'd like you to do a message for Voyager

19:08because if it's going to be circumnavigating the Milky Way galaxy for one to five billion

19:16years, you know, it's like 20 trips around the galaxy.

19:20And there's a very small chance that a space faring civilization would be able to flag

19:27one of them down.

19:29And so on board, you see this exquisite golden disc with scientific hieroglyphics explaining

19:37our address and various basic scientific concepts that we believe that would be common to any

19:48space faring civilization.

19:51And then beneath this exquisite golden disc is the Voyager record, the golden record.

20:00And it contains something like 118 photographs, images of life on Earth, as well as 27 pieces

20:14of music from all around the world.

20:19Many people describe it as the invention of world music.

20:22World music was not a concept that existed before the Voyager record.

20:27And we were determined to take our music, not just from the dominant technical cultures,

20:33but from all of the rich cultural heritage of the Earth.

20:39And there's a sound essay, which is a kind of using a microphone as a camera to tell

20:47the story of the Earth, beginning with its geological sounds and moving into biology

20:57and then into technology.

21:00And I think what you were getting at is that at the end of this sound essay, I had asked

21:08Carl if it were, in the making of the record, it was my honor to be the creative director

21:15of the project, if it was possible to, if I had meditated for an hour while I was hooked

21:23up so that every single signal that was coming from my brain, my body, was recorded and then

21:34converted into sound for the record.

21:39Was it possible that these putative extraterrestrials of the distant future, of perhaps a billion

21:44years from now, would be able to reconstitute this message and to understand it?

21:51And he just, big smile, you know, and just said, well, hey, a billion years is a long

21:56time.

21:57It's a long time.

21:58Go do it.

21:59And so I did this.

22:01And what were you thinking about in the meditation?

22:03Like what, I mean, it's such an interesting idea of recording as you think about things.

22:09What were you thinking about?

22:10So I was blindfolded and couldn't hear anything.

22:17And I had made a mental itinerary of exactly where I wanted to go.

22:23I was truly humbled by the idea that these thoughts could conceivably touch the distant

22:33future.

22:34Yeah, that's incredible.

22:35So in 1977, there are some 60,000 nuclear weapons on the planet.

22:41The Soviet Union and the United States are engaged in a, you know, to the death competition.

22:51And so I began by trying to tell the history of the planet in, you know, to my limited

22:59ability what I understood about the story of the early existence of the planet, about

23:06the origin of life, about the evolution of life, about the history of humans, about our

23:16current at that time predicament, about the fact that one in five of us was starving or

23:25unable to get potable water.

23:29And so I sort of gave a kind of, you know, as general a picture as I possibly could of

23:37our predicament.

23:39And I also was very newly within days of the moment when Carl and I fell in love with each

23:50other.

23:51We had fallen in love with each other long before because we'd known each other for years,

23:55but it was the first time that we had expressed our feelings for each other.

23:59Acknowledged it, the existence of this love.

24:01Yes, because we were both involved with other people and it was a completely outside his

24:09morality and mine to even broach the subject.

24:13But it was only days after that it happened.

24:17And for me, it was a eureka moment.

24:20It was in the context of finding that piece of Chinese music that was worthy to represent

24:28one of the oldest musical traditions on earth when those of us who worked on the Voyager

24:34record were completely ignorant about Chinese music.

24:38And so that had been a constant challenge for me, talking to professors of Chinese music,

24:46listening to musicologists everywhere and all through the project, desperately trying

24:51to find this one piece.

24:54Found the piece, lived on the Upper West Side, found the piece, a professor at Columbia University

25:02gave it to me.

25:04And of all the people I talked to, everyone had said, that's hopeless.

25:08You can't do that.

25:09There can't be one piece of Chinese music.

25:12But he was completely, no problem, I've got it.

25:17And so he told me the story of the piece, which only made it an even greater candidate

25:24for the record.

25:27And I listened to it, called Carl Sagan, who was in Tucson, Arizona addressing the American

25:35Society of Newspaper Editors.

25:40And I left him a message, hotel message center.

25:45And he called me back an hour later.

25:51And I heard this beautiful voice say, I get back to my hotel room, and I find this message

25:58that Annie called.

26:00And I asked myself, why didn't you leave me this message 10 years ago?

26:05My heart was beating out of my chest.

26:09I, it was for me a kind of eureka moment, a scientific breakthrough, a truth, a great

26:19truth had suddenly been revealed.

26:24And of course, I was awkward and didn't really know what to say.

26:27And so I blurted something out like, oh, I've been meaning to talk to you about that, Carl,

26:32which wasn't really true.

26:33I never would have talked to him about it.

26:34We had been alone countless times.

26:36We humans are so awkward in these moments and these amazing moments.

26:41And I just said, for keeps.

26:45And he thought for a very brief, like a second and said, you mean get married?

26:51And I said, yeah.

26:52And he said, yeah.

26:55And we put down the phone.

27:00And I literally was jumping around my apartment like a lunatic, because it was so obvious,

27:10you know, it was something like, of course.

27:12And then the phone rang again.

27:14And I thought, damn, no, he's going to say, I don't know what I was saying.

27:19I am married.

27:20I have a kid.

27:21I'm not going to do this, you know?

27:23But he was like, I just want to make sure that that really happened.

27:27And I said, yeah.

27:28And he said, we're getting married.

27:30And I said, yeah, we're getting married.

27:32Now this was June 1st, 1977.

27:36The records had not been affixed to the spacecraft yet.

27:42And there had been a lot of controversy about what we were doing.

27:47I should say that among the 118 pictures was an image of a man and a woman, frontally,

27:58completely naked.

28:00And there was, I believe, a congressman on the floor that said, NASA to send smut to

28:07the stars, you know?

28:09And so NASA really, they got very upset and they said, you can't send a picture.

28:14And we had done it so that it was so brilliant.

28:16It was like this lovely couple, completely naked.

28:20And then the next image was a kind of overlay schematic to show the fetus inside this woman

28:29that was developing.

28:30And then that went off into, you know, additional imagery of human reproduction.

28:36And it really hit me that how much we hate ourselves, that we couldn't bear to be seen

28:44as we are.

28:46So in some sense that congressman also represents our society.

28:53Perhaps his opposition should have been included as well.

28:55Yes.

28:56Well, that was one of the most vigorous debates during the making of the record with the,

29:02you know, the five, six people that we collaborated with was, do we show, do we only put our best

29:08foot forward?

29:09Or do we show Hiroshima, Auschwitz, the Congo, what we have done?

29:17What do you think represents humanity?

29:20If you kind of, if you think about it, do our darker moments, are they essential for

29:26humanity?

29:27All the wars we've been through, all the tortures and the suffering and the cruelty.

29:32Is that essential for happiness, for beauty, for creation, generally speaking?

29:37Well, certainly not essential for happiness or beauty, that's for sure.

29:40I mean, it's part of who we are, if we're going to be real about it, which is, you know,

29:45I think we tell on ourselves, even if we don't want to be real, we, you know, I think that

29:51if you're a spacefaring civilization, and you've gotten it together sufficiently, that

29:58you can move from world to world, then I think they probably took one look at this derelict

30:05spacecraft and they knew that these were people in their technological adolescence, and they

30:11were just setting forth, and they must have had these issues, you know, because it's,

30:18and so it really, you know, that's the great thing about lying is that a lie only has a

30:24shelf life.

30:25It's like, if like a great work of art that's a forgery, people can be fooled immediately,

30:32but 10 or 15 years, 20 years later, they start to look at it and, you know, they begin to

30:37realize the lens, our lens of our present is coloring everything that we see.

30:45So you know, I think it didn't matter that we didn't show our atrocities.

30:52They would fill in the blanks.

30:54They would fill in the blanks.

30:55So let me sort of ask, you've mentioned how unlikely it is that you and Carl did two souls

31:02like yours would meet in this vast world.

31:06What are your views on how and why incredibly unlikely things like these nevertheless do

31:12happen?

31:13It's purely to me, chance.

31:15It's totally random.

31:17It's a just, I mean, but, and the fact is, is that some people are, and it's happening

31:24every day right now.

31:26Some people are the random casualties of chance and that, and I don't just mean the people

31:33who are being, you know, destroyed in childhood, in wartime, I'm also, or the people who starved

31:41to death because of famine, but also the people who, you know, who are not living to the fullest,

31:52all of these things.

31:53And I think there's a, my parents met on the subway in rush hour.

31:57And so I'm only here with you because of the most random possible situation.

32:03And so I've had this, a sense of this, even before I knew Carl, I always felt this way

32:08that I only existed because of the generosity of the rush hour, no, of just all of the things,

32:17all of the skeins of causality.

32:21It's interesting because, you know, the rush hour is a source of stress for a lot of people,

32:26but clearly in its moments, it can also be a source of something beautiful.

32:32That's right.

32:33Of strangers meeting and so on.

32:35So everything, everything is, has a possibility of doing something beautiful.

32:43So let me ask sort of a quick tangent on the Voyager, this, this beautiful romantic notion

32:50that Voyager One is sort of our farthest human reach into space.

32:55If you think of what, I don't know if you've seen, but what Elon Musk did with putting

33:00the Roadster, letting it fly out into space, there's a sort of humor to it.

33:07I think that's also kind of interesting, but maybe you can comment on that.

33:12But in general, if now that we are developing what we were venturing out into space again

33:20in a more serious way, what kind of stuff that represent since Voyager was launched,

33:26should we send out as a followup?

33:28Is there things that you think that's developed in the next, in the 40 years after that we

33:35should update the spacefaring aliens?

33:38Well, of course now we could send the worldwide, we could send everything that's on the worldwide

33:44web.

33:45We could send, I mean, you know, that was a time when we're talking about photograph records

33:50and transistor radios and, you know, so we tried to be, to take advantage of the existing

33:59technology to the fullest extent, you know, the computer that was hooked up to me from

34:04my brainwaves and my heart sounds while I was meditating was, you know, the size of

34:09a gigantic room.

§03Transcript · 34:11–51:51

34:11And I'm sure it's not that, it didn't have the power of a phone, as the phone has now.

34:17So you know, now we could just, I think we could let it all hang out and just like send,

34:22you know, every week.

34:23I mean, that's the wonder, like I would send, you know, Wikipedia or something and not be

34:30a gatekeeper, but show who we are.

34:34You were also, it's interesting because one of the problems of the internet of having

34:40so much information is it's actually the curation, the human curation is still the powerful,

34:47beautiful thing.

34:48Yes.

34:49So what you did with the record is actually, is exactly the right process.

34:54It's kind of boiling down a massive amount of possibilities of what you could send into

34:58something that represents, you know, the better angels of our nature or represents our humanity.

35:05So if you think about, you know, what would you send from the internet as opposed to sending

35:11all of Wikipedia, for example, all human knowledge, is there something just new that we've developed,

35:17you think, or fundamentally we're still the same kind of human species?

35:24I think fundamentally we're the same, but we have advanced to an astonishing degree

35:32in our capacity for data retrieval and for transmission.

35:37And so, you know, I would send YouTube, I would send, you know, really like think of

35:41all the, you know, I still feel so lucky that there's any great musical artist of the last

35:52hundred years who I revere, I can just find them and watch them and listen to them.

36:00And you know, that's fantastic.

36:02I also love how democratic it is that we each become curators and that we each decide those

36:09things.

36:10Now, I may not agree with, you know, the choices that everyone makes, but of course not because

36:18that's not the point.

36:19The point is, is that we are, you know, we have discovered largely through the internet

36:26that we are an intercommunicating organism and that can only be good.

36:33So you could also send now, Cosmos.

36:36Yes, I'd love to.

36:38I would be proud to.

36:40I mean, you've spoken about a very specific voice that Cosmos had in that it reveals the

36:49magic of science.

36:50I think you said shamanic journey of it and not the details of the latest breakthroughs

36:56or so on.

36:57Just revealing the magic.

36:58Can you try to describe what this voice of Cosmos is with the follow up and the new Cosmos

37:07that you're working on now?

37:09Yes, well, the dream of Cosmos is really like Einstein's quote, you know, it's the idea

37:18of the awesome power of science to be in absolutely everyone's hands.

37:25You know, it belongs to all of us.

37:27It's not the preserve of a priesthood.

37:31It's just the community of science is becoming more diverse and being less exclusive than

37:37it was guilty of in the not so recent past.

37:41The discoveries of science, our understanding of the Cosmos that we live in has really grown

37:50by leaps and bounds and probably we've learned more in the last hundred years about it.

37:58You know, the tempo of discovery has picked up so rapidly.

38:04And so the idea of Cosmos from the 1970s when Carl and I and Steven Soder, another astronomer,

38:13first imagined it was that interweaving not only of the scientific concepts and revelations

38:23and using, you know, cinematic VFX to take the viewer on this transporting, uplifting

38:31journey but also the stories of the searchers.

38:36Because the more I have learned about, you know, the process of science through my life

38:44with Carl and sense, the more I am really persuaded that it's that adherence to the

38:54facts and to that adherence to that little approximation, that little bit of reality

39:02that we've been able to get our hands around is something that we desperately need and

39:08it doesn't matter if you are a scientist.

39:11In fact, the people, it matters even more if you're not.

39:15And since, you know, the level of science teaching has been fairly or unfairly maligned

39:23and the idea that once there was such a thing as a television network, which of course has

39:30now evolved into many other things, the idea that you could in the most democratic way

39:37make accessible to absolutely everyone and most especially people who don't even realize

39:44that they have an interest in a subject or who feel so intimidated by the jargon of science

39:50and its kind of exclusive history.

39:54The idea that we could do this and, you know, in season two of Cosmos, the Space Time Odyssey,

40:01we were in 181 countries in the space of two weeks.

40:06It was the largest rollout in television history, which is really amazing for a, there is no

40:13science based programming.

40:15By the way, just to clarify, the series was rolled out, so it was shown in not that many

40:20countries.

40:21You said we were in.

40:22Well, our show was in 180 countries.

40:25Yeah, the show, which is incredible.

40:27I mean, the hundreds of millions, whatever that number is, the people that watched it,

40:31it's just, it's crazy.

40:33It's so crazy that, for instance, my son had a cerebral hemorrhage a year ago and the doctor

40:43who saved his life in a very dangerous situation.

40:50When he realized that, you know, that Sam and I were who we were, he said, that's why

40:59I'm here.

41:00You know, he said, if you come of age in a poor country like Colombia and Carl Sagan

41:06calls you to science when you're a child, then, then, you know, you go to medicine because

41:13that's the only avenue open to you, but that's why I'm here.

41:17And I've heard that story and I hear that story, I think every week.

41:24How does that make you feel?

41:26I mean, the number of scientists, I mean, a lot of it is quiet, right?

41:31But the number of scientists Cosmos has created is just countless.

41:36I mean, it probably touched a lot of, I don't know, probably it could be a crazy number

41:40of the 90% of scientists or something that have been.

41:43I would love to do that census because I, because that's the greatest gratification,

41:50because that's the dream of science.

41:52That's the whole idea is that if it belongs to all of us and not just a tiny few, then

41:58we have some chance of determining how it's used.

42:03And if it's only in the hands of people whose only, whose only interests are the balance

42:11sheet or hegemony over other nations or things like that, then it'll probably end up being

42:20a gun aimed at our heads.

42:22But if it's distributed in the widest possible way, a capability that we now have because

42:30of our technology, then the chance is that it will be used with wisdom.

42:38That's the dream of it.

42:39So that's why we did the first Cosmos.

42:42We wanted to take not just, as I say, the scientific information, but also tell the

42:48stories of these searchers.

42:53Because for us, and for me, carrying on this series in the second and third seasons, the

43:03primary interest was that we wouldn't tell a story unless it was a kind of a threefer.

43:09It was not just a way to understand a new scientific idea, but it was also a way to

43:17understand what, if it matters what's true, how the world can change for us and how we

43:24can be protected.

43:27And if it doesn't matter what's true, then we're in grave danger because we have the

43:33capability to not only destroy ourselves and our civilization, but to take so many species

43:41with us.

43:42And I'd like to talk to you about that particular, sort of the dangers of ourselves in a little

43:48bit, but sort of to linger on Cosmos.

43:51Maybe for the first, the 1980 and the 2014 follow up, what's a, or one of the, or several

44:00memorable moments from the creation of either of those seasons?

44:07Well, you know, the critical thing really was the fact that Seth MacFarlane became art

44:14champion because I had been with three colleagues, I had been schlepping around from network

44:21to network with a treatment for Cosmos and every network said they wanted to do it, but

44:29they wouldn't give me creative control and they wouldn't give me enough money to make

44:34it cinematic and to make it feel like you're really going on an adventure.

44:40And so I think both of those things, sorry to interrupt, both of those things are given

44:45what Cosmos represents, the legacy of it and the legacy of Carl Sagan is essential control,

44:52especially in the modern world.

44:54It's wonderful that you sought control, that you did not really push it.

44:58And I kept saying no.

44:59And my partners, I'm sure, you know, they would look at me like I was nuts, you know,

45:04and they probably must have entertained the idea that maybe I didn't really want to do

45:08it, you know, because I was afraid or something, but I kept saying no.

45:12And it wasn't until I met Seth MacFarlane and he took me to Fox and to Peter Rice and

45:21said, you know, I'll pay for half the pilot if I have to, you know, and Peter Rice was

45:25like, put your money away.

45:27And in every time since, in the 10 years since, at every turn, when we needed Seth to intervene

45:39on our behalf, he stood up and he did it.

45:43And so that was like, in a way, that is the watershed for me of everything that followed

45:51since.

45:52And I was so lucky because, you know, Steve Soder and I written the original Cosmos with

45:58Carl and collaborated on the treatment for season two.

46:04And then Brennan Braga came into our project at the perfect moment and has proven to be

46:13just the, really, I have been so lucky my whole life.

46:17I've collaborated, I've been lucky with the people, my collaborators have been extraordinary.

46:23And so that was a critical thing.

46:26But also to have, you know, for instance, our astonishing VFX supervisor who comes from

46:33the movies, who heads the global association of VFX people, Jeff Okun.

46:39And then, you know, I could rattle off 10 more names, I'd be happy to do that.

46:46And it was that collaboration.

46:49So the people were essential to the creation of...

46:52Absolutely.

46:53I mean, when it came down, I have to say that when it came down to the vision of what the

46:58series would be, that was me sitting in my home, looking out the window and, you know,

47:04really imagining like what I wanted to do.

47:06Can you pause on that for a second?

47:07Like what's that process?

47:08Because it, you know, Cosmos is also, it's grounded in science, of course, but it's also

47:13incredibly imaginative and the words used are carefully crafted.

47:19Thank you.

47:20So what's...

47:21If you can talk about the process of that, the big picture, imaginative thinking, and

47:28sort of the rigorous crafting of words that like basically turns into something like poetry.

47:35Thank you so much.

47:37For me, these are rare occasions for human self esteem.

47:44The scientists that we bring to life in Cosmos are people, in my view, who have everything

47:55we need to see us through this current crisis.

48:00They're, very often they come, they're poor, they're female, they're outsiders who are

48:09not expected to have gifts that are so prodigious, but they persevere.

48:19And so you have someone like Michael Faraday, who comes from a family, dysfunctional family

48:26of like 14 people and, you know, it never goes to, university never learns the math.

48:33But, you know, is the, you know, there's Einstein years later looking up at the picture of Faraday

48:42to inspire him.

48:44So it's, you know, if we had people with that kind of humility and unselfishness who didn't

48:54want to patent everything, as, you know, Michael Faraday created the wealth of the 20th century

49:02with his various inventions.

49:05And yet he never took out a single patent at a time when people were patenting everything

49:09because that was not what he was about.

49:13And to me, that's a kind of almost a saintliness that says that, you know, here's a man who

49:20finds in his life, this tremendous gratification from searching.

49:28And it's just so impressive to me.

49:30And there are so many other people in Cosmos, especially the new season of Cosmos, which

49:34is called Possible Worlds.

49:36Possible, beautiful title.

49:37Possible Worlds, well, I stole it from an author and a scientist from the 1940s.

49:44But it, for me, encapsulates not just, you know, the exoplanets that we've begun to discover,

49:53not just, you know, the worlds that we might visit, but also the world that this could

50:00be, a hopeful vision of the future.

50:03You asked me what is common to all three seasons of Cosmos or what is that voice?

50:08It's a voice of hope.

50:10It's a voice that says there is a future which we bring to life in, I think, a fairly dazzling

50:17fashion that we can still have, you know?

50:21And in sitting down to imagine what this season would be, the new season would be, I'm sitting

50:27where I live in Ithaca, beautiful, just gorgeous place, trees everywhere, waterfalls, I'm sitting

50:35there thinking, well, you know, you can't, how do you, how do you awaken people?

50:41I mean, you can't yell at them and say we're all going to die, you know?

50:45It doesn't help.

50:47It doesn't help.

50:49But I think if you give them a vision of the future that's not pie in the sky, but something,

50:59ways in which science can be redemptive, can actually remediate our future.

51:06We have those capabilities right now, as well as the capabilities to do things in the Cosmos

51:15that we could be doing right now, but we're not doing them.

51:19Not because we don't know how to, how, you know, with the engineering or the material

51:24sciences or the physics, we know all we need to know, but we're a little bit paralyzed

51:30in some sense.

51:33And you know, we're like, I always think we're like the toddler, you know, like we, we left

51:39our mother's legs, you know, and scurried out to the moon.

51:43And we had a moment of, wow, we can do this.

51:46And then we realized, and somehow we had a failure of nerve and we went scurrying back

§04Transcript · 51:51–1:08:29

51:51to our mother and, you know, did things that really weren't going to get us out there,

51:56like the space shuttle, things like that, because it was a kind of failure of nerve.

52:02So Cosmos is about overcoming those fears.

52:07We're now as a civilization, ready to be a teenager venturing out into college.

52:12We're returning back.

52:13Exactly.

52:14Exactly.

52:15And that's one of my theories about our current situation is that this is our adolescence.

52:25And I was a total mess as an adolescent.

52:28I was reckless, irresponsible, totally.

52:31I didn't, I was inconsiderate.

52:34I, the reality of other people's feelings and the future didn't exist for me.

52:41So why should a technologically adolescent civilization be any different?

52:46But you know, the vast majority of people I know made it through that period and went

52:55on to be more wise.

52:59And that's what my hope is for our civilization.

53:02On a sort of a darker and more difficult subject in terms of, so you just talked about the

53:10Cosmos being an inspiration for science and for us growing out of our messy adolescence,

53:18but nevertheless, there is threats in this world.

53:22So do you worry about existential threats?

53:25Like you mentioned nuclear weapons, do you worry about nuclear war?

53:30Yes.

53:31And if you could also maybe comment, I don't know how much you've thought about it, but

53:34there's folks like Elon Musk who are worried about the existential threats of artificial

53:40intelligence.

53:41Sort of our robotic computer creations sort of resulting in us humans losing control.

53:49So can you speak to the things that worry you in terms of existential concerns?

53:54All of the above.

53:55You don't have to be silly, you know, like not to think and not to look at, for instance,

54:00our rapidly burgeoning capability in artificial intelligence.

54:09And to see how sick so much of the planet is not to be concerned.

54:16And sick is an evil potentially.

54:18Well, how much cruelty and brutality is happening at this very moment?

54:25And I would put climate change higher up on that list, because I believe that there are

54:32unforeseen discoveries that we are making right now, for instance, all that methane

54:39that's coming out of the ocean floor that was sequestered because of the permafrost,

54:47which is now melting.

54:49You know, I think there are other effects besides our greed and short term thinking

54:56that we are triggering now with all the greenhouse gases we're putting into the atmosphere.

55:02And that worries me day and night.

55:04I think about it every single, every moment, really, because I really think that's how

55:10we have to be.

55:11We have to begin to really focus on how grave the challenge is to our civilization and to

55:23the other species that are.

55:26It's a mass, this is a mass extinction event that we're living through.

55:31And we're seeing it.

55:32We're seeing news of it every day.

55:35So what do you think about another touchy subject, but what do you think about the politicization

55:40of science on topics like global warming and bionic stem cell research and other topics

55:46like it?

55:47What's your sense?

55:48Why?

55:49What do you mean by the politicization of global warming?

55:53Meaning that if you say, I think what you just said, which is a global warming is a

56:00serious concern, it's human caused and maybe some detrimental effects.

56:05Certainly there's a large percent of the population of the United States that would, as opposed

56:10to listening to that statement, would immediately think, oh, that's just a liberal talking point.

56:20That's what I mean by politicization.

56:21I think that's not so true anymore.

56:22I don't think our problem is a population that's skeptical about climate change because

56:30I think that the extreme weather and fire events that we are experiencing with such

56:37frequency is really gotten to people.

56:40I think that there are people in leadership positions who choose to ignore it and to pretend

56:50it's not there, but ultimately I think they will be rejected.

56:55The question is, will it be fast enough?

57:00I think actually that most people have really finally taken the reality of global climate

57:09change to heart and they look at their children and grandchildren and they don't feel good

57:16because they come from a world which was in many ways, in terms of climate, fairly familiar

57:24and benign and they know that we're headed in another direction and it's not just that,

57:29it's what we do to the oceans, the rivers, the air.

57:35You ask me, what is the message of cosmos?

57:40It's that we have to think in longer terms.

57:46I think of the Soviet Union and the United States in the Cold War and they're ready to

57:50kill each other over these two different views of the distribution of resources.

57:57But neither of them has a form of human social organization that thinks in terms of a hundred

58:05years, let alone a thousand years, which are the time scales that science speaks in.

58:11And that's part of the problem is that we have to get a grip on reality and where we're

58:19headed and I'm not fatalistic at all, but I do feel like, and in setting out to do this

58:30series each season, we were talking about climate change in the original cosmos in episode

58:37four and warning about inadvertent climate modification in 1980.

58:46And of course, Carl did his PhD thesis on the greenhouse effect on Venus and he was

58:52painfully cognizant of what a runaway greenhouse effect would do to our planet.

58:58And not only that, but the climatic history of the planet, which we go into in great detail

59:02in the series.

59:03So yeah, I mean, how are we going to get a grip on this if not through some kind of understanding

59:11of science?

59:12Can I just say one more thing about science is that its powers of prophecy are astonishing.

59:22You launch a spacecraft in 1977 and you know where each and every planet in the solar system

59:32is going to be and every moon and you rendezvous with that flawlessly and you exceed the design

59:39specifications of the greatest dreams of the engineers.

59:44And then you go on to explore the Milky Way galaxy and you do it, I mean, you know, the

59:51climate scientists, some of the people whose stories we tell in cosmos, their predictions

59:59were, and they were working with very early computer modeling capabilities, they have

60:08proven to be so robust, nuclear winter, all of these things.

60:12This is a prophetic power and yet how crazy that, you know, it's like the Romans with

60:19their lead cooking pots and their lead pipes or the Aztecs ripping out their own people's

60:26hearts.

60:27This is us.

60:28We know better and yet we are acting as if it's business as usual.

60:35Yeah, the beautiful complexity of human nature, speaking of which, let me ask a tough question

60:45I guess because there's so many possible answers, but what aspect of life here on earth do you

60:49find most fascinating from the origin of life, the evolutionary process itself, the origin

60:55of the human mind, so intelligence, some of the technological developments going on now

61:02or us venturing out into space or space exploration, what just inspires you?

61:07Oh, they all inspire me.

61:09Every one of those inspire me, but I have to say that to me at the origin of, as I've

61:14gotten older, to me, the origin of life has become less interesting because I feel, well,

61:22not because it's more, I think I understand, I have a better grasp of how it might've happened.

61:31Do you think it was a huge leap?

61:33I think it was a, we are a byproduct of geophysics and I think it's not, my suspicion of course,

61:42which is take it with a grain of salt, but my suspicion is that it happens more often

61:50and more places than we like to think because after all the history of our thinking about

61:56ourselves has been a constant series of demotions in which we've had to realize, no, no, so

62:04to me that's...

62:05We're not at the center of the solar system.

62:06And the origin of consciousness is to me also not so amazing if you think of it as going

62:12back to these one celled organisms of a billion years ago who had to know, well, if I go higher

62:22up, I'll get too much sun and if I go lower down, I'll be protected from UV rays, things

62:30like that.

62:31They had to know that or you, I eat, me, I don't.

62:34I mean, even that, I can see if you know that, then knowing what we know now, it's just,

62:41it's not so hard to fathom.

62:43It seems like, I've never believed there was a duality between our minds and our bodies

62:50and I think that even consciousness, all those interesting things seem to me, except one

62:57of the things...

62:58A byproduct of geophysics.

62:59Yeah, all of chemistry, yes, geochemistry, geophysics, absolutely.

63:07It makes perfect sense to me and it doesn't make it any less wondrous.

63:12It doesn't rob it at all of the wonder of it.

63:19And so, yeah, I think that's amazing.

63:21I think we tell the story of someone you have never heard of, I guarantee, and I think you're

63:27very knowledgeable on the subject, who was more responsible for our ability to venture

63:34out to other worlds than anyone else and who was completely forgotten.

63:40And so, those are the kinds of stories I like best for Cosmos because...

63:44Can you tell me who?

63:45No, I'm going to make you watch this series, I'm going to make you buy my book, but I'm

63:53just saying, this person would be forgotten, but the way that we do Cosmos is that I ask

64:03a question to myself, I really want to get to the bottom to the answer and keep going

64:08deeper, deeper until we find what the story is, a story that I know because I'm not a

64:14scientist.

64:15If it moves me, if it moves me, then I want to tell it and other people will be moved.

64:22Do you ponder mortality, human mortality, and maybe even your own mortality?

64:28Oh, all the time.

64:30I just turned 70, so yeah, I think about it a lot.

64:34I mean, it's, you know, how can you not think about it?

64:37What do you make of this short life of ours, I mean, let me ask a sort of another way,

64:48you've lost Carl, and speaking of mortality, if you could be, if you could choose immortality,

64:58you know, it's possible that science allows us to live much, much longer.

65:02Is that something you would choose for yourself, for Carl, for you?

65:05Well, for Carl, definitely.

65:07I would have, you know, in a nanosecond, I would take that deal.

65:12But not for me.

65:13I mean, if Carl were alive, yes, I would want to live forever because I know it would be

65:17fun.

65:18But no.

65:19Would it be fun forever?

65:20I don't know.

65:21That's the essential nature of the...

65:22I don't know.

65:23It's just that the universe is so full of so many wonderful things to discover that

65:29it feels like it would be fun.

65:31But no, I don't want to live forever.

65:33I have had a magical life.

65:37I just, you know, my craziest dreams have come true.

65:42And I feel, you know, forgive me, but this crazy quirk of fate that put my most joyful,

65:54deepest feelings, feelings that decades later, 42 years later, I know how real, how true

66:00those feelings were.

66:02Everything that happened after that was an affirmation of how true those feelings were.

66:09And so, I don't feel that way.

66:12I feel like I have gotten so much more than my share, not just my extraordinary life with

66:20Carl, my family, my parents, my children, my friends, the places that I've been able

66:31to explore, the books I've read, the music I've heard.

66:36So I feel like, you know, if it would be much better if instead of working on the immortality

66:44of the lucky few of the most privileged people in this society, I would really like to see

66:51a concerted effort for us to get our act together, you know?

66:55That to me is topic A, more pressing, you know, this possible world, that is the challenge.

67:04And we're at a kind of moment where if we can make that choice.

67:11So immortality doesn't really interest me.

67:14I really, I love nature and I have to say that because I'm a product of nature, I recognize

67:23that it's great gifts and it's great cruelty.

67:27Well, I don't think there's a better way to end it, and thank you so much for talking

67:33to us.

67:34It was an honor.

67:35Oh, it's wonderful.

68:09And now let me leave you with some words of wisdom from Carl Sagan.

68:14What an astonishing thing a book is.

68:17It's a flat object made from a tree with flexible parts on which are imprinted lots of funny

68:23dark squiggles.

68:24But one glance at it, and you're inside the mind of another person, maybe somebody dead

§05Transcript · 1:08:29–1:09:13

68:29for thousands of years.

68:32Across the millennia, an author is speaking clearly and silently inside your head, directly

68:37to you.

68:39Writing is perhaps the greatest of human inventions.

68:43Finding together people who never knew each other, citizens of distant epochs.

68:50Books break the shackles of time.

68:53A book is proof that humans are capable of working magic.

68:59Thank you for listening, and hope to see you next time.
