It has been explained to me that “Space” is finite essentially because we can measure things, distance, size, speed of light, ect. Therefore, if “Space” is finite then everything else is finite.
I understand that if you have an infinite number of stars in a finite space then there would be light everywhere for example. I don’t understand why the same would be true if the universe were also infinite. Would that not sort of cancel out the infinite nature of any one object as it would have infinite space to be in.

Space is still expanding faster than light so yes, it is infinite. The strange part of it is is you were to try and get to a planet that is 100 light years away, because of the expansion, if you travel at the speed of light, you would never reach it. You would actually have to travel at light speed plus the additional speed the space between here and there is expanding at.
