As I am not a bigot I have no problem with dark energy or dark matter.
I still can not get my head around the idea that the Universe has no center. I have no reason to think that the center is anywhere near me but it seems that it should have one.
If the universe is infinite in all directions then I can see how every point could be considered the center. If there was a point somewhere in the past when the universe was not infinite in extent then there must have been a center. If it started as a dot then what happened to that spot?
When you blow up a balloon, where is the center of expansion on the surface of the balloon?
I realize that this is an analogy but the center is the same place it was before you inflated it. I do not understand where we make the jump from Euclidean to non Euclidean geometry
