Is the universe infinite?

god don't know nigga

At least in one dimension and one direction it is finite - the past.

Speaking of big bang - space and matter was supposedly finite back then. Seems very illogical to get infinity out of a finite amount of stuff in a finite amount of time. In what moment it became infinite?

Another thing - since the universe is expanding, it will be bigger tommorow, than it is today. How can it be more infinite?

Thanks!

most certainly not

We don't know, and cannot know.
Flat also doesn't necessarily imply infinite.

"Prove this physical space is infinite"
"Well from these axioms it would seem..."
"Prove your axioms are complete and valid"
"..."

Infinite vs finite is all feels. I choose to think the universe is probably, in some manner, finite because it intuitively feels correct based on what I know and the biases in the machinery of my mind. That is all, nothing more, nothing less, nothing grand, and no Truth.

The current model predicts that the universe is expanding and will slow down, but never quite stop, so that at infinity v = 0.

So, yes.
