An astrophysicist reacts to Carl Sagan's Contact

[@theukdave2433]

If I remember WAY back to some astronomy modules at uni, doesn't radio telescope resolution go by the distance separating the receivers, so the VLA would probably have a finer resolution than Arecibo ... it will surely have lower sensitivity as you say, but perhaps resolution is what was being referred to in the film? I mean, probably not, I guess they were trying to find faint signals, but still!

[@marksusskind1260]

About hearing the signal, think dramatic license: it's more dramatic to show someone listening to sounds from space than watching curves move and shake on a monitor.

[@charlesbradshaw3281]

@@theukdave2433 You are correct, the VLA has much more resolution, but less sensitivity than Arecibo. Also, Arecibo is limited by it's pointing, since directivity in the antenna beam depends more on the earth's position. In the movie, the signal was enormous for a radio (10s or 100s of Janskies, I forgot which).

[@charlesbradshaw3281]

@@marksusskind1260 I actually had the "no way" response to Ellie's listening to an interferometer, but, when I asked some of the old timers at the VLA, I was told that they used to do that. The way you hear a signal is to detect it with the output of a spectrum analyzer. You can hear any amplitude modulation simply by connecting ear phones or a speaker to the detected output. In the movie, the signal was amplitude modulated, as are pulsars. The movie actually used radio astronomers from the VLA as technical advisors.

The scene where the dad tells the little girl what she pointed at, and Dr. Becky's reaction, is what happened 2 nights ago with my 9 yr old daughter. I live on the south coast of England and we were looking south at about 19:30 and she asked what the bright star was (Rigel) and the coloured one further up (Betelgeuse). After listening to the reaction I was so pleased with myself for knowing these and being able to answer my daughters' questions.

I'm a musician and an engineer, and I had a young guitar student once. My lab and my studio were in the same space in an old mill building in NH, and when this one boy would come for lessons, he was often more interested in the things I was working on. I used to feel bad that he wasn't getting enough time in actual guitar instruction, but if he was interested in things, I'd show him. In the end, the science took as well, and when I spoke to his mom a while back, he was studying astrophysics in Florida. Sort of made me happy.

[@markshirley9353]

Regarding listening by ear .... In the novel (p.53): "She sat down before one of the consoles and plugged in the earphones. It was futile, she knew, a conceit, to think that she, listening on one or two channels, would detect a pattern when the vast computer system monitoring a billion channels had not. But it gave her a modest illusion of utility." We should cut the filmmakers some slack when Carl Sagan himself had her do this.

[@mdomans]

Signals guy here - that explanation actually fits, Sagan would work with people who did a lot of analog signal work. Most transmission tech we have today (serious data streams, not hobbyists) is practically not something a human being can even begin to decipher or even diff from background Doesn't change the fact that people love tech they can feel physically - I remember an old research institute lab where folks preferred their ethernet over BNC cause they use BNC more and you can hook it up to oscilloscope. I'd not be at all surprised someones listens to some channel, even for fun, sometimes those sounds are quite nice (sorting algos sound nice too).

[@TolgaPala]

Thank you. I would have upvoted your comment a hundred times if I could.

[@DerkleineTrojaner]

I'm NOT criticising Sagan as a Scientist nor as a Science Communicator. I do however criticise him a bit as a fiction writer. In this little quote you did i feel like i can hear him, like actually his real self talking instead of an undefined, all-knowing narrator. Because he's clearly trying to convey to the reader how utterly futile her illusion of an attempt was. And i feel like that's just Sagan talking and not, as i said, the narrator.

[@markshirley9353]

@@DerkleineTrojaner I hadn't thought of the passage that way (that it was Sagan's voice coming through and maybe anticipating criticism from his colleagues). That sounds right to me. But I also think his having her listen that way is a quirk that humanizes her and paints a clear picture in the reader's mind. There's a reason that most of the posters for the movie show Jodie Foster with headphones in front of the VLA . That communicates "listening for signals from space" faster than anything else could have. That's why I think Dr. Becky's criticism on this point is misplaced. In a work of fiction or art, writers decide all the time to have characters to things that are right dramatically even if technically wrong. And Bob Zemechis' repeated use of the image suggests he agreed.

[@gozer33]

Also, it works so well in the movie. Jodie Foster listening with open eyes, but seeing only with her imagination. Very iconic.

[@StarkRG]

A lot of what was in the books that they changed resolves a lot of what you didn't like about the movie. The pod they sent held five or six people, each of which confirmed they'd been gone for 18 hours (or whatever it was), so the question was about whether the travelers had conspired to create this story in order to legitimize the expense. The 18-hours of static was mentioned near the end but it was never explicitly stated that the information would be released to the public. That said, there was resolution to the story in that Ellie discovered something that the alien had told her about that even they, with their advanced technology and many more years of research hadn't been able to figure out. She then accidentally figures out the answer that is implied will completely turn science and society as a whole on end (though I'm pretty sure the explanation in the book is ridiculous, but then, it would kinda have to be). Ellie _does_ listen to the radio signals (I think she rigs up her own contraption), but it's viewed as quirky by everyone else. It's mentioned that she _knows_ that the data analysis will find a signal better than she ever could, but it makes her feel connected to her father who taught her ham radio. Sagan actually did "participate" in an observation session at Arecibo and found it to be _extraordinarily_ boring, so he probably added that to make it seem more hands-on.

[@briankelly6561]

Another addition: in the book the aliens state they will "close down" their end of the portal so future attempts at contact will fail, making the experiment unrepeatable. The question is then about whether you believe Ellie (and the other travelers in the book) on if what they experienced was real. This is a refence back to the science vs religion theme of the movie and points out that science isn't always completely without faith.

[@AnimeCritical]

Can you please tell me what the problem was that the aliens could not figure out?

[@zemoxian]

@@AnimeCritical Tl;dr: we contacted a type III civilization that could use wormholes to travel. They were seeking clues to the whereabouts of the type V? civilization that created the wormholes. That civilization apparently left the universe to search the cosmos for the creators of our universe. I won’t even guesstimate their Kardishev number. I don’t remember the details but the transportation network that the galactic civilization used to make contact wasn’t made by them. It was made by an older and far more advanced civilization that had gone away. I think the expression was something like they had gone over the cosmic horizon or something like that. They were searching for clues found in a message described as some higher form of mathematics that humanity was nowhere near grasping. They described it as if she turned her search algorithms on pi and she found a message hidden in the noise of the digits. BTW, she did just that and in base 11 there was a very long string of 1s and 0s that was the product of two prime numbers in length. Arranging them into a rectangle formed an image of a circle and a line that was a little over three times its diameter. I think the creators of the wormhole transportation network solved those mathematical problems and went off to seek their origin. Which I suppose was an even more advanced form of life, presumably with the technology to manipulate the fabric of reality to the point that they can embed pictures in fundamental mathematical constants like pi. While that kinda implies they may have been the creators of our universe, it didn’t seem like they were actually God, just extremely godlike from our limited perspective. There’s a whole cosmos to explore beyond the limited confines of our tiny blip of a universe.

[@rodylermglez]

@@rebeuhsin6410 In the novel it is also explained that the aliens have highly advanced neuroimaging technology and use it to appear to contactees in the shape of someone similar to them in order to avoid triggering a seemingly completely universal xenophobic response (a thing Ellie didn't repair into until the last second when she started to dread about tentacles and whatnot). Therefore, each crew scientist meets an alien in the image of someone dear to them, alive or dead, and at an age when they had really nice memories of them. As a bonus, the aliens also find not only scientifically but aesthetically pleasing how some species psychés experience dreams and memories. It was also a need to connect with other sentient life in an unfathomable largely empty universe the thing that drove them to try and keep contact with as many civilizations as they could, establishing a multi-star array of radiotelescopes SETI program. They seem to value the psychological phenomenon of dreams in sentient species so much that they even "trade" in them.

I wrote my Junior Year (high school) thesis on black hole dynamics. This was not long after Cygnus X-1 was discovered. My biggest takeaway from "Cosmos" was this quote: "I am in _earnest_ about faith; I do not _play_ with it". I can still hear Carl Sagan's voice in my head as I type his quotation of... Nicholas Copernicus, a deeply religious astronomer, and major figure in the history of science. Sagan, an atheist himself, pulled his punch in the book. They did try a couple more times to use the machine, but it never worked. Ellie had set up the SETI computer net to search for a repeating pattern in PI... came home one day to find it printing out a perfect circle. Proof of the existence of God. "For Carl"... he was dying of cancer as they were making the movie. The car Ellie was laying on at VLA was, I believe, a Pontiac Catalina, 1969...

I didn't think the part about the earphones was that unrealistic. I've seen documentaries which showed astronomers observing pulsars with radio telescopes. They converted the radio signal to an audio one so we could hear the "sound" of the pulsar - which sounded awesome, btw.

[@tracyavent-costanza346]

yep, and the more recent "mars sounds" downloaded from martian robots and/or satellites, just underscores that humans want to have direct experiences. Becky also gave that idea some juice when she mentioned noticing that stars had COLORS. The HR major sequence is about far more than "color" but color is the part that we can directly experience (as long as the light is bright enough). And SETI is not really looking for "light" from the star. We know they produce light. We want to find out if there is anything ELSE they produce. Even with the light, we know that produces an absorption spectrum, which tells us a lot about the HR classification hence a crapload about the chemistry of the star. Recently JWST was launched in part, to do something similar with the chemistry of known exoplanets. We fully expect to find more from those IR and near-visual signatures, to tell us about atmospheric content in those bodies, and NOT really light from the star; rather light absorbed by the exoplanet's atmosphere as it occults the star.

[@cameronlapworth2284]

Yes I've done this too listening to storms on Jupiter with a diy radio telescope. Diy people listen to pulsars this way too. But even in the script they conceded it not something anyone else does anymore. The microwave background radiation was detected as audio hiss by accident and after cleaning off the pigeon crap and trying everything to get rid of the audible hiss they checked with a local university who was proposing to build a radio telescope to look for it and realised they'd been scooped accidentally. So failure to pick up on context. Many a backyard astronomer has become a real astronomer starting with home made telescopes and using literal radio to literally listen to light. Astonomers don't generally literally look through telescopes now either but the connection to the characters childhood ham radio and observation and her adult pattern of listening (inspire of all the computer recordings etc.) Is th point here. It's a narrative method to connect child Ellie with Adult Ellie.

@@cameronlapworth2284 Great comment! Also, Carl definitely understood his reader/audience.

Also, there would be some very dull scenes in this film if the didn’t use sound during the scenes they do. It makes me think back to when I was a DJ for my college radio station, our student leader had written on a couple of sheets of paper and posted throughout the room, “DEAD AIR IS NOT YOUR FRIEND!” Ellie stating at a computer screen, alone, just there in case the scopes picked up a signal would not have worked, it would have been the movie equivalent of dead air - a character not moving much and no dialogue.

Dr. Becky, I recently found your list-of-things-we-don't-know video. Your material and manner of explanation forced me to binge watch a dozen of your videos. This is something I never do. I feel that your style makes astrophysics accessible, intriguing, and fun for both laypeople and the scientific community. I also happen to be an atheist, and like you, I feel that, in an infinite universe, there always must be infinite information we DON'T know. So having the hubris to believe we have all the answers and everyone else is wrong makes little sense. As you mention, the great thing about science is that it is (or should be) based on facts. We just want the truth, so when we learn new data, we're excited to change our minds and explore the new ideas that this data opens up for us. We should not be trying to force ideas to fit our preconceived notions. Also, I'm not sure science is the right tool to answer, "why." It's great for "what" and "how," but "why" is a more subjective and philosophical question. I'm happy admitting I don't know why and leaving that to philosophers. If forced, I would say that everything in the universe exists because the laws of the universe allow it. Otherwise it couldn't exist, right? So the supernatural can't exist, because if it did, it would be natural, by definition. So a supposed supernatural event would simply be one of the infinite number of events about which we have not yet learned. So, in that case, like in your video, our answer should be that we don't know. But maybe some day.. . . Have a wonderful vacation. Thank you so much for all you do. I look forward to your next video.

I've always considered this film to be a meditation on the relationship between science and faith - more specifically between what we can explain and what we believe. While they are initially seen as being in tension, the scientist ends up as a believer in something she can't explain. There's also a rhetorical loading of the dice in the repeated formulation that "If it's just us, it's a pretty big waste of space" - an argument that assumes the existence of someone to have a purpose for creating the universe the way it is.

Perhaps to please Carl Sagan, the director should had suggested tat in the movie, the team had already written/developed an algorithm that could somehow modulate real-time deepspace radiowave signal into audible audio signals to be played by speakers so those observers could "listened" to it all day long while multi-tasking. Then when there is an anomaly they could had picked it up by ears and rush into work immediately during the narrow window.

[@Guido_XL]

Indeed, it would have been all too blatantly stupid for script-writers to pretend that radio-waves could be heard without any decoding. Of course radio-waves are electromagnetic waves, propagating at the speed of light. We all know that. But just like terrestrial radio-waves have to be decoded by either amplitude or frequency demodulation, so could radio-waves from outer space be decoded as well. The movie does not disclose such information, as it would demand too much science and technology knowledge from the general public, but a movie like Contact would not attempt to pretend that a radio-astronomer would act against laws of physics and get away with it. The story wants us to contemplate the idea of getting in contact with aliens, it does not need to distract attention from that focal point by casually throwing in easily detectable errors that unnecessarily harm our credibility in the story altogether. So, of course the movie script depicts radio-astronomy more or less according to scientific and technological reality, as far as the daily business of radio-astronomy is concerned. Demodulation of radio-waves ought to be a part of that. Listening to demodulated radio-waves is not that far off. We can also listen to the sound of bats, when their chirps are being demodulated first. The speed of the waves is not the decisive property here. It's about frequencies and their modulation. Signal processing can go through great lengths to change the perception of whatever information might be transmitted.

[@Guido_XL]

@@bmcquillan You said: "listening for a single, somehow modulated, signal in the raw data might be useful." Radio-waves propagate at the speed of light. They also have the property of frequency, and wavelength, being the ratio of propagation speed (the phase speed) and frequency. But, as long as there is no modulation (either natural or artificial) of that wave, there is no signal to detect. We call it a signal if we can interpret a message from it, one way or another. The analog terrestrial radio-broadcast waves apply radio-waves in the hundreds of kiloherz [kHz] to hundreds of mega-herz [MHz] range. But, if those waves would just propagate towards our antennas and would not contain any information, they would just be received as unmodulated sine-waves, if they would carry the property of a single frequency. Once that wave however is being modulated, we cannot identify a single frequency anymore, unless the modulation is purely amplitude-driven. Hearing hundreds of kHz or even MHz is out of the question anyway. Radio-communication is about modulation and demodulation of a carrier-wave. We do not hear the carrier-wave, we hear the demodulated information from that carrier after the signal has been processed. If I remember "Contact" correctly (but it is quite some time ago that I saw the movie), we see how the scientists and technicians decode the message from outer space. They apply frequency demodulation and detect subcarriers. This is FM (frequency modulation) in action. The aliens transmitted bursts of messages in which frequency-modulated information had been packed. They practically broadcasted a TV-recording in bursts. What Jodie Foster's character heard while listening to the signals was the large-scale chirp-envelope of those bursts. It is perfectly possible to hear those chirp envelopes in their low frequency range. She did not hear the modulated frequencies themselves (i.e., the carrier-waves), she heard the envelopes of the modulated carrier-bursts. There is nothing strange nor unscientific about that.

[@flmbray]

I loved the book.... The movie not so much, because they (mostly) left out something that (for me) was a HUGE detail.... In the book, when she is meeting the alien, he is describing how they (the aliens) went through their own process of discovery about the universe. He describes how the number PI is irrational and thus never terminates and never enters an infinitely repeating series of digits, but their mathematicians continued to calculate more and more digits of PI, and eventually found a very long string of 0's, at which point they thought that maybe it did terminate. But as they continued to calculate even more digits it turned into just 1's and 0's, and they discovered that it was a message that could be decoded, just as Dr Arroway had decoded the message from the aliens. Ellie then asks something like... "But how could that be? PI is a number that's built into the natural fabric of the universe?" to which the alien answers something very simple like "Exactly." Yes, it conjures up a bit of Intelligent Design, but the point was that despite the incredible knowledge and technology that the aliens had provided to us humans, there was something even deeper and more meaningful embedded into the universe.

Cheap compared but they go with the planes so add it to the total cost. And theres those littoral trimaran ships and the drone fighter planes. This is adding up. :) There's a reason we dont have any fighter jets in our air force here in New Zealand, we couldn't afford one F35 or more than one F22.

Yeah, the aliens gave her a tip to check pi in base 11. Also in the book, they set up a fancy program that watch for patterns in otherwise random data. So, she set up one program to calculate digits of pi, fed the numbers to the pattern-watcher, and let it run for quite a long time. At the very end of the book, it found a pattern. THAT was a really stunning idea. Mathematical constants like pi are.... sheesh, we don't have good words to describe it. They are independent of physical reality. You could throw away the entire universe and make a new one with completely different laws of physics, and pi would still be the same. A message in pi wouldn't be from the creator of the universe, it would be from the creator of the rules that universe creation has to follow. Actually, even that doesn't make sense because 'creation' means making something that wasn't there before, which means time is ticking, which means you are already in a universe.

[@sjh3217]

So some of your questions are answered in the novel (which I HIGHLY recommend; goes so much more in depth than the movie). For all its scale and expense, all the Machine is capable of doing is making a small divot on the fabric of spacetime, which hooked onto the "nozzle" of the aliens' wormhole network. After they sent Ellie back (and her four companions; book Machine seats five), they severed the link on their end. We could reactivate it, but it wouldn't send anyone anywhere. The aliens only wanted to give our species a glimpse of what's in store if we reach our potential, but they can't do our growing up for us. In time we'll take the next step in our evolution, and they'll be waiting for us again when we do. And her appearing to go nowhere is explained by the aliens having to correct for causality violations caused by wormhole travel. From the outside, a clean causality happens to look like a broken Machine. As for the 18 hours of static - if you look closely during the scene when Ellie exits the Capitol, the crowd is reaching toward her almost as a religious figure. The govts don't believe her, but the world does, so I think they feel that if it came out that they have evidence vindicating her story it would swell that fervor to a point that they can't control. Plus, I think there's just a simple fear by the powers that be of what it really means if she's right. In the novel, the aliens were literally building galaxies during the Cambrian explosion on Earth (Cygnus A is one of many such projects, undertaken by beings from many galaxies, with the aim of testing tech that might avert the Heat Death of the universe). They claim to be friendly, but we are NOTHING compared to them. And they hinted at others even older than they. The govts don't just censor the evidence in the book, and her story - they blackmail her by threatening to release psychiatric dossiers that would make her look insane if she didn't keep her mouth shut.

Becky, your channel is incredible and the videos you make are absurdly enlightening! Thank you for everything! I found the part about "listening" to the signals very interesting. Even though it's not something typically done in the scientific process, "listening" to a change in the signal is something that many of us, including myself, enjoy doing. When I was a kid, I had a cheap shortwave radio and I liked listening to the signal variations in AM or SSB. It's kind of science-y, really, but hearing the static noise varying with the changes in the ionosphere was fascinating (and a bit crazy, though lol). This part reminded me, for example, of when the scientists at LIGO and VIRGO published the conversion of gravitational waves from the collision of two black holes into sound.
