Another cool part: the universe is expanding. That means the thing you're looking at is moving away from you as you're looking at it. The speed at which it moves away increases the further it is away from you (like a dough expanding in the oven, you're the raisin in the bread). But the speed of light is constant. So combining these two facts, it means there are things that are so far away that they move faster away from us than the light they can emit to reach us, which means their light never reaches us. Never.

It's your (personal) edge of the universe.
