Is this a case of more people paying after midnight on Super Bowl Sunday? Like yeah it's Monday, but 2am.

I've heard the analogy used that you can think of 3D space as flattened onto the surface of a balloon which is expanding. No matter which direction you take, you always end up back where you started (after a relativity breaking amount of time.

Edit: as the balloon expands, the actual material expands similar to how spacetime is expanding. Interestingly, at some point eons into the future, this expansion will make the milky way an island where everything else is so far away, any future civilization will never receive its light and will think our galaxy is all that exists in the universe.
