Here is another question:
How can astrophysicists describe the universe as infinite and expanding at the same time? If the universe is already infinitely large, how could it be expanding? Where is it expanding to? ...another infinity?
Hi.
I'm not a student of physics, so please forgive me for my ignorance. I only have a very simple question.
If the observable universe is about 93 billion light years in diameter, how could the universe have reached that size in only 13.7 billion light years? Doesn't it stand to reason...
