I know the universe doesn't expand at a speed but rather a rate over distance but if we take two objects on opposite sides of the observable universe, would they be moving away from each other at a greater rate than light? IE if object A was a star and object B was a planet, would the light from the star still be able to reach the planet or would they be moving away from each other faster than light can catch up? And that got me thinking, what if the univere is finite and a galaxy on the "edge" of the universe were to emit light, that light would travel away from the galaxy but only at some point there literally wouldn't be anymore universe for the light to travel into so what happens? To me at least everything we know about the universe (which isn't very much to be honest) but enough for me to think that an infinite universe just makes so much more sense than a finite one. Isn't it much more likely that the universe is infinite because if the universe is everything that exists then it must, by it's own definition, be unbounded and infinite?
