Can light reach the edge of the universe?
Unfortunately, since universe is technically expanding faster than the speed of light (due to the expansion of space between matter), it is theoretically impossible to ever reach the “edge” of the universe, since it will always be moving away faster than we could ever move towards it!
Is the edge of the universe moving faster than the speed of light?
Due to the expansion of the universe, it is true that two objects, far enough from each other, could actually move faster than light relative to each other. That means light sent from one of them would never reach the other. However, the speed of light, no matter how you measure it, is always the same.

How far can we travel across the universe?
Put that all together, and this means the distance we can see in the Universe, from one distant end to the other, is 92 billion light years across. And don’t forget: it’s continuing to expand! If we left today at the speed of light, we could only reach about a third of the way across it: approximately 3\% of its volume.
Why is the universe expanding so fast?
At this juncture, the universe itself was also expanding. The inflation of the universe slowed after the first initial burst, but since then, the rate of expansion has been steadily increasing due to the influence of dark energy. Essentially, since its inception, the cosmos has been growing at an ever increasing rate.
Is the universe infinitely big?
While the universe is probably not infinitely big, it is very very large. So large, in fact, that light from all corners of the universe have not had time to reach us yet. That defines one kind of edge: the observable universe, or the part of the universe in which light have had time to reach us.
