Okey, there is one thing thats really pissing me off, how come everywhere the phrase "universe" is used when actually they are just talking about the visible part of the universe
if we use the word "universe" for our visible universe only, that would mean we are exactly in the center of the universe because we can see equal length in all directions.
according to what iv read there is no way to measure the size nor the center of the universe because it expands equal everywhere and not in the sense of an explosion.
so the other thing that annoys me, why do we think we know so much about the big bang? iv heard multiple places that in the beginning the entire universe would fit in our hands, but then they had to just be talking about the visible universe again.
Because if we knew that then we could easily calculate the entire size.
our visible universe could be as big as 180billion light years wide, with about 100billion galaxies, any suggestion then to the full size of the universe?
