What's with this recent hopium trend where people seem to think that we'll become a space-faring utopia?

      emh if it makes you happier if you know special relativity you'd know that if you go real fast in proportion to the speed of light, space contracts so it doesnt look like that much time passes for you (like wise people on earth will see you experience time slower) so while you would still take decades or centuries to get anywhere you wouldnt feel much of that

        In a strange way, even our isolation gets folded between space and time by relativity. We're not technically trapped in space, since subjectively we can go as fast as we want.

        But if you travel for a few years at high rapidity, you'll probably never see those again who you left behind, because centuries or millenia might pass for them. And when you arrive, you'll arrive at a different place than you set out to, because all that time passed there, too. Maybe twice as much time, if you consider that what you set out towards was a image that has to travel to you first.

        So the more we spread out in space, the more we are trapped in little pockets of time, shared only by those travelling together.

          this is what happens when people take too many creative writing classes and not one science one,

            I've never taken a writing class, and I do general relativity as my day job. What does that say about me?

              oh my im sorry i just feel like everyone here is super pumped on philosophy, history, writing etc and so everytime you have to debate soemthing from science nobody is prepared and they get out these fake-deep considerations which make me cringe a bit, i thought you were part of that crowd

              what jobe has you have to take in consideration GR daily? other than physics teacher/scientist, what, orbital eletronics?

                No worries, I might have gone to hard on the prose there. The issue of desyncronization is a real problem, though, and it puts a hard limit on the coherence of any hypothetical multi-system civilization.

                I'm doing a PhD in theoretical physics right now, specializing in numerical general relativity, i.e. black hole/neutron star/gravitational wave simulations. So, nowhere near as useful as orbital electronics.
