Another cool part: the universe is expanding. That means the thing you're looking at is moving away from you as you're looking at it. The speed at which it moves away increases the further it is away from you (like a dough expanding in the oven, you're the raisin in the bread). But the speed of light is constant. So combining these two facts, it means there are things that are so far away that they move faster away from us than the light they can emit to reach us, which means their light never reaches us. Never.
It's your (personal) edge of the universe.
Same concept I was talking about.

Well but they can't expand past the speed of light, light is still faster
Expansion may well be faster than light because the speed limit for the latter is in a vacuum, in space, inside the universe, but the universe, hence space itself expands.
The speed of light may not be constant. Light could have been much faster in the early universe.
No evidence of it not being constant
How does this affect Bitcoin when we break past the bounds of earth? How is a 10 minute block enforced when gravity dilates time more in some places than others?
This is a valid issue
It is. Bitcoin can't travel through timespace.
Each colony will need its own, with some swap tech placed at the midpoint
Ever wondered why the sky is dark at night?
Does it MATTER?
Geddit... dark matter... :D
