  • forget what’s real, I want to write a story with humans interacting with aliens that’s consistent with what we see now.

    You just have to make it a bit sci fi. Like say it’s the year 2400 or whatever and Earth achieves radio contact with another civilization. Maybe they’re 100 light years away so you’d jump 200 years every time a message is sent and returned. Not sure how you’d tell that story but that’s the most realistic thing I can think of.



  • our current theories are probably downright primitive to any advanced life form and there’s undoubtedly blind spots in modern day science

    “All due respect”, this is pure speculation. We may very well be at a close approximation of physics and have a reasonably accurate understanding of the limitations. Or we may not be. But there is not really much of a reason to think that what we know now about the limitations of the universe (like the speed of light) should somehow be upended by new discoveries or theories.


  • “Something” is much more likely to be aircraft from Earth or atmospheric illusions or hundreds of other possibilities and the probability of it being actual aliens is basically 0%.

    Why won’t the US gov tell us or show us everything they have?

    Isn’t it also funny that all these UFO sightings almost exclusively happen in the US, the country seemingly obsessed with UFOs? And other countries basically don’t see them at all?

    Also isn’t it weird that despite giving literally everyone and their kid a smartphone with high resolution cameras, we still haven’t gotten any convincing footage of any alien UFOs? You’d think if there were aliens, someone would’ve filmed them by now (hint: there are no aliens on earth to film).

    Doesn’t that make you at least a little curious?

    Yes, it is easy to fall into this “I want to believe” trap. Of course it makes us curious. But that should not blind you from what is real.

    imagining someone traveling using wormholes or other technologies humans have no clue about

    Our current physical theories suggest that there is no “shortcut” to travelling between the stars and it will likely not become any easier with future technology. There is no way around light speed and conservation of momentum.

    I don’t doubt that alien civilizations would want to visit if they knew we existed - we certainly would want to visit another civilization if we knew it existed. But the problem is that it’s just not physically feasible. The most likely scenario is that we achieve some kind of radio communication with another civilization.

    No amount of technology will let you go faster than light. There’s no reason to believe that technology will just keep expanding and allow us to somehow travel easily to other star systems. Actually our current understanding of physics seems to suggest that we might never be able to do that.

    Just because we want it to happen doesn’t mean it will or that we should think it will. Hope is not equal to truth, unfortunately.


  • I touched on this a bit here. But basically I think the fermi paradox essentially just tells us that life, multicellular life and intelligent life are much rarer than we think they are.

    I don’t know if nuclear engines would change too much when it comes to space travel between the stars. I mean let’s say you could reach even 1% of the speed of light (which is already bonkers honestly). That’s still quite slow all things considered. Just to cover, say 1% of the Milky Way’s diameter (100.000 light years) would be a distance of 1000 light years. With 1% light speed, that would take you 100.000 years. That’s simply not viable.


  • More of a conjecture that fell out of some math, but can’t exist in the real world.

    To be fair, you could have said the same thing about black holes at some point. But even if wormholes exist, they may not be “constructable” or anything of that sort. It may just as easily be a hole from nowhere to nowhere and you can’t change it or move it, it’s just there.



  • There’s advanced aliens out there. They know about us.

    1. There might be advanced aliens out there, but very likely not within the distance our signals have travelled so far.
    2. They almost certainly don’t know about us, because again, our signals have probably not even reached them.

    If you ask me, Fermi’s paradox is much more likely to overestimate how likely advanced life is. It may be that multicellular life is just extraordinarily rare and that Earth is essentially unique in this aspect, or maybe it has only happened in a few other places. Even then, intelligent life could be another extremely rare occurrence.

    Wormholes is a purely theoretical idea, we have not observed any. There are no scientifically viable FTL drives that fit our current theories. Something like an Alcubierre drive would require exotic matter with negative mass, which we also have no idea if is even possible. It probably isn’t possible.

    Because if not, I’d say we can’t that for certain.

    This is Russell’s teapot. You can’t say “we can’t rule it out, so maybe it’s true!”. Extraordinary claims require extraordinary evidence. Aliens visiting earth is a super duper extraordinary claim. You need extremely convincing evidence to go against the pure common sense that the distances are so vast that visiting other star systems (let alone the solar system) is near impossible.


  • People who believe aliens have come from other star systems to visit us must not have a very good idea of the distances involved in the universe.

    You can’t imagine how far away other stars are. Like seriously, it’s bonkers far away. The idea that an intelligent civilization would randomly arrive on Earth at this very time where we exist is absurd. And I mean that, because the journey would at least take thousands of years. They would not have come because they heard our signals or anything like that, because at the time they set off, we were in the stone age.

    The idea of aliens visiting earth is just absurd if you actually know the distances involved, but unfortunately a lot of people think stuff works like in the sci fi movies and the aliens will just click their warp drive button and instantly arrive because “alien technology” or whatever. But it doesn’t work like that in the real world.



  • Nothing exactly. But that’s okay, because the fediverse data is available to all, which makes it worthless, monetarily speaking. Nobody will sell your data to anyone. Any AI company could use the data to train their models, but they wouldn’t be able to sell those models since they wouldn’t be any better than an open source model. The fediverse levels the playing field and doesn’t allow the situation where Google pays reddit for AI training data.
