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!

@@theukdave2433 You are correct, the VLA has much more resolution, but less sensitivity than Arecibo.

@@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.

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.
@mdomans2 жыл бұрын
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).

@@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.

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.
@briankelly65613 жыл бұрын
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 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.

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.

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. Yeah, definitely an entity way into the "unimaginable" category.

Any 'signal' has to be modulated in some way in order to carry information - AM, FM, phase shift, digital pulses at some data rate. A signal intended for detection by anyone listening will likely have an obvious modulation, which might well manifest as repetitive sequences of sound if extracted from the carrier wave.

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.

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. I spent hours listening to that, even though it was a simple "whistle", but hearing that process was extremely satisfying. Your video is incredible!

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_XL3 жыл бұрын
@@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.

$1.7trillion divided by 2,500 planes is $680m per plane. Coincidentally I read approximately 680 have been built so far. The new Gerald R Ford aircraft carrier has a unit cost of $13.3billion so far, times 10 ships, plus $37.5billion program costs, so only $170.5billion total... if it all works, to replace the current carrier fleet over the next few years. 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. Our air force is about transporting cargo to disaster areas, taking our army around the world, ocean search missions in Orions and Hercules', and flying the Prime Minister places in their 757's. I think they are about to replace the Hercs and/or Orions.

10:41 The signal is actually prime numbers, between 2 and 101 if I’m remembering correctly, so there’s little doubt it’s an actual alien signal. Otherwise you’d be right about it taking years for data analysis. But that wouldn’t work in a movie, so Carl wrote in that it’s unambiguously an alien signal, because no natural phenomenon would by happenstance produce that result. I’m an historian and am used to movies having to take some liberties to keep a film (entertainment not as pure documentary) interesting, to simplify complex issue(s) and to keep a film to a reasonable length of time. Sometimes, film makers go too far in this respect. I think Carl did an excellent job in both the book and film (he was working with the people making the film, but died before it was completed and reached the theater.) I find this reaction video frustrating because it seems like you missed or forgot a lot of what happened in this movie.
@sandal_thong863110 ай бұрын
As they said somewhere in the book, it's coming through pretty strong, so once alerted to it, pretty much anyone could turn a receiving dish to Vega and get the signal. I can imagine someone alerting tabloid journalism, and it just mushrooms. Not just there, but at any radio telescope in the U.S., Europe and elsewhere.

Then he got me my first telescope and I remember another time Saturn was high enough above the horizon to look at it. This little blurry gray thing but just enough prevision to make out the rings. To see some stripes on jupiter. Learning how to find Andromeda and seeing that blurry blotch in the sky best seen from my periphery. How to identify all the planets.

Hi Doc, In Pre-production, the makers of the film decided to change one of the messages of the film. The most notable was the machine itself. In Sagan's novel, the machine was more like the machine in the TV Series Sliders, a dodecahedron-like machine that spun more like a ride at a State Fair inside a huge assemblage of if hanger-like buildings, than a spheroid dropped through an artificial "worm whole" on ramp to an intra- galactic network of wormhole passages triggered by programed conveyances, like her capsule. Whew. The visuals tell the story better than I do. The reason? People expected to see something "big and huge out there on Cape Canaveral!" And that's why the machine got changed. People were not quite ready for the Science. I hope we get an Asteroid moving module built long before we need it for Apophis. V/r., Robin

It'd be more plausible that the entrance point of the wormhole was used as a reference and the aliens adjusted the return wormhole to deposit her at almost the exact spacetime coordinates as when she left. So time dilation did occur, but that's not why observers on Earth saw what they saw.
