If this fact makes you uneasy just know that 100% of the universe's galaxies, except the one we are currently in, are already unreachable within your lifetime.

Pretty much true for all other stars as well… we’re not visiting anywhere soon

If this fact makes you uneasy just know that (nearly) 100% of the galaxy's solar systems except the one we're currently in are (likely) unreachable within your lifetime. Though to be fair, I think the original title can't possibly know this, for instance if we live in a simulation, what's to say that some sort of algorithm (assuming we learn to meta-code our own existence) could put us in any galaxy we choose... Or warp drives, worm holes... light speed travel hardly seems worth the trouble, and unfeasable.. but if we can master warp drives, and bending space around us... then is there a limit on max speeds? If we can actually reprogram the universe would there be anything we couldn't do? have any other alien civilizations realized that at all?

  100% of this solar system's other planets and moons are (likely) unreachable by you within your lifetime.

    Nearly 100% of the countries on this very earth are unreachable to most poor humans within their lifetime. And for a sizeable chunk of humans even reaching the very neighbourhood of their country, geography involves putting their lives on risk on a near sure to sink boat only to be shot/sent/sunk back by border police. Humans are horrible at working together for their own good.

  We don’t love in a simulation. Get off the dumb rich guy juice.

  If we're in a simulation then there aren't any alien civilizations. No sense wasting computational resources on them. P.S. As far as I know, computational complexity is the only physical quantity that doesn't obey conservation laws. So we're probably not in a simulation. If we were, it would probably be the other way around.

    Why wouldn’t aliens work in a simulation model? The universe could be a shared sandbox to cross pollinate models or expose them to similar realities. Hah.

    If we are in a simulation it’s most likely a physics/first-principles driven simulation… probably a “what if physics worked like $X” type of deal. So fidelity is likely the primary design goal and the weird nature of computational complexity in our universe is likely just an emergent property of the physics they setup the simulation with.

      We seem to be living in some sort of an information complexity singularity, and it seems to be getting more complex exponentially with time. No, I don't think this is some sort of accidental emergent property. Likely the information complexity singularity is the whole point.

Mmmh. Probably. I'd throw an asterisk on this... technology advances in ways we don't expect, and the definition of "lifetime" might become very fuzzy very quickly. (I don't think I'd put 50/50 odds on it... but I wouldn't put 1/99 odds on it either).

That depends on whether the singularity people were right after all or not.

Not with that attitude! Longevity escape velocity is achievable within our lifetimes.
