I find it intresting that IF the universe is infinite, and an object traveled for tens of billions of light years in one direction, that after all of that traveling, it would have traveled 0 % of that infinite universe.
Now that's saying something about what it could mean if the universe is infinite.
If the universe is infinite, and is expanding, then there has to be " stuff " far away that is moving away from us much much faster than the speed of light. And if this is so, perhaps the expanding is stranger than we think, ( has properties we don't grasp ).
Btw, the expansion, as far as I can comprehend it, also protects us from ultra deep space ultra deep time gravity forces that given even the slightest uneven distribution likley would tear our atoms apart, but can never act on us because space expanding prevents that gravity from ever reaching us. ( As far as I can figure it, re what's going on ).
This is especially so if the age of the universe is also infinite.
