"This is actually really fascinating, because it's one of those areas where cosmology gets kinda...squicky. As a rule, no object can move through space at faster than the speed of light. But the expansion of the universe itself is not measured as a speed, which is distance over time, but rather as a speed-per-unit-distance, meaning that there is no physical bound to its upper limit. So, while it is true that the universe contains a finite amount of space, it is also simultaneous true that no matter how fast you move, you can travel infinitely in one direction and never reach the edge of the universe."
