The Ultimate Interstellar Valentine Mix Tape 75

Hugh Pickens writes "NPR reports that toward the end of the summer of 1977, NASA launched two Voyager spacecraft that each included a golden record containing, among other things, the sound of a kiss, a mother's first words to her newborn child, music from all over the world, and greetings in 59 different languages. The records on board were meant to survive for a billion years, in the hope that some day, against enormous odds, they might cross paths with an alien civilization. The record was a special project of Carl Sagan with the help of Ann Druyan, creative director of the project. For Druyan, though, the summer of 1977 and the Voyager project carry a deeply personal meaning because it was during the Voyager project that she and Sagan fell in love. Then Druyan had an idea for the record: They could measure the electrical impulses of a human brain and nervous system, turn it into sound, and put it on the record so that maybe, 1,000 million years from now, some alien civilization might be able to turn that data back into thoughts." (More, below.)
"Just a few days after she and Sagan declared their love for each other, Druyan went to Bellevue Hospital in New York City and meditated while the sounds of her brain and body were recorded. According to Druyan, part of what she was thinking during that meditation was about 'the wonder of love, of being in love.' And the gold records? They're still out there with their offer, to whomever might stumble across them, of a human body newly in love. 'Whenever I'm down, ' says Druyan, 'I'm thinking: And still they move, 35,000 miles an hour, leaving our solar system for the great open sea of interstellar space.'"

        Why would that matter? It's not like it's going to stop moving after the power runs out. The alien civilization that builds an entire freaking ship around the probe and fixes its programming so that it can continue on a far bigger exploration mission can probably manage to add a power source.

      It's not distance. It's time. You're thinking in hundreds or thousands of years, and that's simply absurd. After leaving the Solar System, these probes will be lost in an inconceivably large expanse of space. Voyager 1 is due a close approach to the red dwarf star AC+79 3888 in about 40,000 years - where 'close approach' means a distance of 1.6 light years. And that's mostly because that star's moving towards the Sun, rather than Voyager moving towards it. Voyager 2 has no such close encounter planned, though it will come within a few lightyears of Sirius in about 300,000 years.

      For comparison: 40,000 years ago the last Neanderthals were wandering Spain. 300,000 years ago... well, there's evidence of the use of fire.

      And that's the timescale for a close approach to a star of the order of a lightyear. To actually be found, unless someone out there has godlike sensor technology (in which case there's no point trying to hide anyway), they'd have to come a lot closer in than that. Millions of years? Billions? These probes are small, and in a few decades their transmitters will fall silent and their radioactive cores die and their metal structures cool to the ambient temperature of deep space. They'll be hard to spot.

      Don't think of this as a message. Think of it as a time capsule. By the time they're found, if they ever are found, then whatever is living on Earth won't be H. sapiens any more. If there even is an Earth by then, or a Sun. The record doesn't say 'Here we are' - it says, 'Here we were'.

Many believe that mankind will still exist in our present form in another 7 billion (with a B) years from now when the sun engulfs the Earth.

        • To retrieve Voyager would be... difficult. Fantastically expensive. But not impossible.

          Assuming no exotic physics - no warp, no inertialess space drive, you fly around using recoil from throwing mass out the back at high speed - then the best we can probably hope for is a fusion rocket. It would have to accelerate to an immense speed to catch Voyager. Then brake to match velocities, actually recover the probe, come to a complete stop and accelerate back to Earth, stop again, and deliver cargo.

            I'm not suggesting that it is something which would be done in the next century with chemical rockets.

            Yes, I'd agree, it would have to be either a fusion rocket or something powered with anti-matter as fuel for energy density, and if it is using a reaction mass that the "exhaust" is moving at a significant fraction of the speed of light with an ISP that is incredible.

            That said, collecting Voyager at some point in the future is something that I believe will be possible. Records are currently kept both on it

    It might sound charming to talk about Ann Druyan and Sagan falling in love. This was Sagan's nth marriage for large n. The first one was with biologist Lynn Margulis. Then later to artist Linda Saltzman. He had serious problems in his personal life. And many people who knew Sagan speculated that the final marriage would have probably eventually broken up as well if not for the fact that Sagan died. Sagan was an amazing scientist and publicizer of science but his personal life was very dysfunctional. Not at all someone I would try to emphasize on Valentine's Day unless I was trying to make a point about the inherent ridiculousness of so many romantic claims. Anyone who wants to know more about this fascinating figure should read Keay Davidson's biography of Sagan.

    I heard about this story on NPR yesterday. It's a neat story, and I had never heard about it previously. The line about aliens reconstructing the recording back into thoughts started me thinking though. It seems absurd, but how could you show it was absurd using science and not just opinion? The first thing that came to mind was measuring the information content in the recording, and trying to estimate the information content in thoughts. If the information content in the recording Information content of the thoughts, it is impossible to reconstruct the recording into thoughts no matter how advanced the technology. Brain waves have a very low frequency. On the order of 4-13 Hz. Even if you're able to cram several bits/Hz, that's still a very small amount of information. So the question remains, how to measure the information content of thoughts?

    • Impossible to answer at present. As another responder said, Shannon's information theory tells us that a signal can be highly redundant or noisy: its information content depends on how much of the garbage you can remove and still reconstruct the message.

      But you can only figure that out if you have a *receiver* which can detect and reformulate the signal. We can measure the brain's electrical signals, but we have no idea how to turn those back into thoughts. Until we can do so, we have no way to tell whic

  • Ok, so hang on, record brain impulses in the hope that someone can reconstruct them as thoughts? That's like saying "I'm going to record the hard drive and fan noises on my computer in the hope that someone can reconstruct the game I'm playing". Riiiight. That sounds like trying to get small pieces of a complex whole and expecting someone to be able to make use of it. And I thought Sagan was supposed to have been a respected scientist?

It is easier to write an incorrect program than understand a correct one.
