Sorry if this is so vague, but I was thinking about space and my brain can’t comprehend how the universe is infinite. To my understanding the universe “model” is that it’s kind of oval shaped and we come back right where we started. But wouldn’t that make the universe finite because there has to be something beyond that? Maybe I’m missing something and that’s why I’m confused.

No expert, but it might depend on how you look at it. If you say the universe is all the matter, anti-matter, energy and so on, then I’d say that is a finite amount of stuff. But if you say the universe is the space that contains all of that, then I’d say that space is infinite. It’s just mostly empty.
While my brain can’t comprehend infinity either, I find it easier to “accept” an infinite emptiness than an infinite amount of matter. Because if there were a wall, I’d ask what lies behind the wall. But if there is no wall, if there is nothing, you don’t wonder what’s behind it. There is nothing. For it to end there had to be something at some point. But if there isn’t, then there is just more of nothing.
