Has dark energy been proven to exist?

To my knowledge, an infinite universe doesn't go very well with an infinite one. Because if it's expanding, it's expanding from something. That means that it originates somewhere, and that means it's not infinite.

 

I read some old 60s book on astronomy that suggested an "ever creating" universe, which is basically creating matter out of nothing at some point, and then expanding like we think our universe does at the moment. So I guess that would be a valid universe by your example, but there's not a lot to suggest ours is one of those.

 

Well, what exactly is expanding?

We see the contents of the universe traveling away from something. Maybe their origin; as you say. But, does that mean the universe, or an infinite shell of the universe, was not already there?
