. There would need to be a central point for the stars to attract to. So does that happen? Now Im confusing myself because it doesnt seen like stars do that in space since I also read that every body is attracted to eachother, not a central point of the universe, which could also mean the universe IS infinite?......
Isaac Newton realized that, according to his theory of gravity, stars should be attracted to eachother (each body in the universe is attracted toward eachother body by a force called gravity)
So in order for stars to be attracted to each other and inward, there would need to be a finite number of stars and a finite region amount of space, since if there was an infinite amount of stars and infinite region of space there would be no central point but any point would be central since each side of the point would be an infinite amount of stars... There would need to be a central point for the stars to attract to. So does that happen? Now I'm confusing myself because it doesn't seen like stars do that in space since I also read that every body is attracted to eachother, not a central point of the universe, which could also mean the universe IS infinite???
No.
Newton started with the premise that the universe was static. This he believed to be true simply because every observation at the time told him that the distant stars were fixed. And you're right ... in the sense that he tried to explain the static universe by arguing if the universe was infinite then gravitational forces would balance and there would be no single point the universe could collapse to.
Except the mathematics of infinity hadn't be developed at that point. If you do the calculation properly, then you find that actually, an infinite universe would still collapse! The way to do it properly is that an infinite universe looks the same everywhere. So you pick a point anywhere in the universe and it will be representative of anywhere else. You start off with a small region of space. It would collapse due to gravity. If you make that region larger, it would still collapse. If you make that region even larger, it would still collapse. And so on out to infinity. And since it doesn't matter what point you started with, an infinite universe must therefore collapse due to gravity!
