The universe is infinite, or at least appears so. The cosmic background radiation was because the early universe was hot everywhere. However, I’ve been telling my wife that the universe didn’t start from a single point; it has always been infinite. The concept of “smaller” is only because the matter was less dispersed than it is today. Veritasium’s video seems to support this argument.
She’s pointed towards a few different articles saying that the most accepted theory of physics is that the universe started from a single point, and that there is language such as “it grew to the size of an apple” within a small amount of time after the Big Bang.
How can both views be correct? Either the universe isn’t infinite, and therefore has some kind of edge, or it is, and has always had infinite size.
