Link to the original Space Thread Hi! This is the thread to discuss general space and space exploration-related things, as well as adjacent topics. Such topics can include, but are not limited to: JWST news, rover news, future missions to the outer planets, theoretical cosmology, explanations about general or special relativity, exoplanets, speculative biology, the Fermi Paradox, SETI, space settlements, the ethics of space exploration, the Kardashev Scale, UAPs-as-possibly-aliens-but-skeptically, and so on. While we're definitely more free to speculate about far-future concepts, we aim for at least a "Hard Sci Fi" level of skepticism. Think of it as orbiting around Isaac Arthur-level. If you crave hard-nosed aerospace industry news and space rocket live streams, let me refer you to the Spaceflight Thread in SAL. If shooting the poo poo about alien visitations, reincarnation, and the Age of Aquarius is more your vibe, the UFO thread in CSPAM is probably your place. We welcome everyone! I know that the Space Thread has at times been oddly contentious, given the subject, but I am sure that if we go forward with the idea that we shouldn't take things too seriously, take extraordinary claims with a grain of salt, and approach everything with a skeptical but open mind, things will be all right! nervous laughter Recommendable Video Channels: Cool Worlds with Prof. David Kipping Anton Petrov Science Fiction and Futurism with Isaac Arthur Event Horizon with John Michael Godier JWST appreciation station If you haven't heard, we deployed the James Webb Space Telescope recently and it's been A M A Z I N G yeah!! gently caress yeah!!!

Also, for content - did anyone catch that interview with Grusch? I missed it. https://www.newsnationnow.com/space/ufo/we-are-not-alone-the-ufo-whistleblower-speaks/ Reading the summary of it, it... seems like a whole load of nothing. Pretty much like a rehash of every other whistleblower interview on this subject. quote:“Well, naturally, when you recover something that’s either landed or crashed … sometimes you encounter dead pilots and, believe it or not, as fantastical as that sounds. It’s true,” Grusch said. Uhhhhhh-huh. I dunno, smells like a disinfo op to me.

https://www.youtube.com/watch?v=Rl2ap0m6fGk Okay, this is just cringeworthy at this point. Instead of ooh and ahh-ing over being so incredibly lucky as to catch a big meteor like that on camera (even with sonic booms and break-apart sounds!!), everyone is crawling over themselves to scream about th' alieeums! I went to watch the Geminids in the mountains this past winter and they looked absolutely the same. Same composition probably, because the fireballs I saw were greenish. It was fantastic, actually, one of the best and most cosmic things I'd ever seen in my life.

Ok, in the grand scale of things, 100M isn't even that much, even when talking about space projects. Next, let's be totally generous and say that yes, SETI is almost invariably committing anthropomorphism by searching for signals that would be intelligible to us: is that truly an unreasonable thing to do, though? In the vast set of all possible civilizations, perhaps SETI would only discover signals, were they to be discovered, that would come from beings resembling us -- you have to ask if it would even be worthwhile to try to communicate with beings that don't. Think of it like internet dating: say you trawl through ten thousand people - would you prefer to connect to the first bozo that swipes right that has nothing in common with you, or spend time connecting to someone who has a ton of common ground?mediaphage posted:ah yes famous technological spacefaring civilization earth whales Star Trek IV was a documentary.

It turns out all UFO visitations/sightings/close encounters were true, all of them, and were attempts at first contact but we just can't understand alien behavior nor can they understand us, because ~aliens. Blipping around very quickly and disappearing, implanting weird little pieces of metal, being shot down all the time by primitive apes with boomsticks, and making patterns in grass is just how their culture expresses greetings and conveys important information.

I enjoyed Foundation too, and that one's characters are just kind of talking exposition puppets.

To return to the issue of possibly missing intelligent signals in SETI because of too much anthropocentrism in our approach, I think that while it's fair to raise the issue that other intelligent species might express themselves and produce an "intelligence signal" in ways we might not expect, I feel like you need to draw the line somewhere. We have no other reference point for what the behavior of an intelligent civilization would be other than our own, so the most conservative action would be to look like signals that could be produced by a civilization like our own. Otherwise, if you're too liberal in your definitions for intelligent behavior, without any other a priori boundaries, I feel like there'd be too much of a chance for false positives. Would patterns of jets of water from Enceladus be an intelligent signal? If you include too many unexplained phenomena it risks labeling every suspicious phenomenon as SETI signal. EDIT: Oh I think we're talking cross-purposes here lol.

Well, see, the thing is that unlike other "public intellectuals", the thing which distinguishes Avi Loeb as uniquely bad is the fact that he just stole artifacts from another country, and one of the poorest countries on earth at that! "Violating the laws of a foreign country" puts you on a different axis! On a scale of annoyingness, I'd put Avi Loeb above NDGT, who is quite far above Michio Kaku. In terms of smugness, Avi Loeb is just slightly below NDGT. In terms of Woo, Avi Loeb is in the middle between NDGT at one pole while Michio Kaku is at the other.

I AM GRANDO posted:It’s nothing until there’s incontrovertible proof that it’s something. If aliens were visiting the Earth, wouldn’t literally anything be different? If alien technology has been in the hands of the US and its contractors for ~100 years and they’ve never been able to learn anything from it, what difference would it make? I wish I knew what this guy was actually being prevented from learning about. So, if the claims put forth are taken at face value -- what Grusch had said about these UAP capabilities defying known laws of physics and so on -- then what that would imply is that all our known laws of physics and science are wrong, on a fundamental level. All of the Standard Model and General Relativity, which have been tested at accuracies up to one part in one hundred trillion and one part in ten trillion respectively, are essentially bullshit. We would need to rewrite everything from Newton on up. In fact, probably the basis of what we understand to be rationality itself would be undermined. I feel like if that was true, I'd feel incredibly sad and mournful.

I AM GRANDO posted:Science doesn’t really work that way. The dude’s lying and there aren’t any ufos, but if there were then whatever physics they’re doing would have to be compatible with what we know is true. GPS doesn’t invalidate anything in newtonian mechanics just because it requires relativity to operate, just like Mercury’s orbit doesn’t prove that gravity is false. Anything you can do with Newtonian physics is still possible. I'd think that if the UAPs were clearly and obviously violating basic principles like non-locality, relativity, thermodynamics, the speed of light, and so on, but yet the same rules still applied to our everyday experience and measurements, then the case would be highly strengthened towards there being some kind of interference in our measurements, our perception of cause and effect. The simulation hypothesis -- or interference with our perception to such a severe extent that it reduces to the simulation hypothesis -- would gain a much higher credibility. In that case, we could not be sure that anything we measure or experience was not the direct result of some alien intelligence pulling the wool over our eyes, meaning that "true" reality might follow rules that were completely unknown to us. For example, what we observe to be the cosmic microwave background might actually just be a kind of illusion created at the boundaries of our solar system, or a kind of hologram, or even just bit-level alterations in our instrumentation created at the moment of measurement. My point is that if you accept the "UAPs are violating fundamental principles of physics" thesis, then we may as well toss out science entirely and return to mysticism.
