Just to add to it:
If you decided to travel to the furthest galaxies you could reach, at some point even they will move beyond the reach of Earth as space expands. To colonize them means to exile yourself from Earth permanently.
Traveling through an infinitely expanding universe is like traveling into a permanent headwind in every direction.
- HKH2 5y agoIf you can handle being 'exiled' from the past permanently, what difference does it really make?
- gremlinsinc 5y agoWhat if we're in a simulation, and algorithmically there's a way or method that will drop you in any coordinate at any time in the universe's timeline so that you can indeed explore space, and return home for dinner? I mean it'd require a TARDIS to exist probably lol, but in a sim, why not? Of course if we're in a sim, then that's probably not part of our overall 'goal' for creation, and likely we're the only creatures created so exploration really won't satisfy us, other than total galactic conquest, but then what?
- brundolf 5y agoWeird question I just thought of: if space is always expanding, why aren't the objects around us, even their very atoms, getting slowly torn apart? Are the forces holding them together just constantly pulling them back together? Is it just a very small amount of expansion at a human scale? Does this affect very sensitive measurements of distance?
- c21h30o2 5y ago> Are the forces holding them together just constantly pulling them back together? Is it just a very small amount of expansion at a human scale? Both. Even our galaxy is held together by gravity that's stronger than the expansion of space on that scale.
