yeah, i wonder how fast you have to go to actually be able to physically move to a certain distance in space since everything is flying away from us.

i don't think anything will look like what we see from here if we were travelling fast enough to slow down (blue shift) the light coming towards us, whether it would be where you saw that it was, by the time you get there.

it's a total mind-blinder to think about. i mean, if you could teleport to the position, it wouldn't be the position anymore, everything would have long since moved to a new position. and if it's expanding, it would be proportionally that much further away.

We could take the speed of light and infer where the object will be when we arrive, so we aim for that spot. But if we have anything wrong with our understanding of space expansion or light, then we'll miss and everyone will die.
