Isn’t that still open for debate? I mean that’s the half of the quote I omitted… The observable universe is finite. But kind of per definition. And time seems to be finite, too. Started 13.8 billion years ago. And if the other dimensions (space) are finite or infinite kind of depends on the shape of the universe, which we don’t exactly know. As far as I know data from telescopes hints at the universe being flat. Which would point to space being infinite.
And I mean “infinite and expanding” is kind of inconsistent in itself, isn’t it? It has to have some border that grows for it being able to expand. Or it’s infinite… But then it can’t really expand anywhere… I can’t see how it can be both at the same time.
But I’m not an astronomer. I could be totally wrong.
yet the universe is probably infinitely large, and expanding.
