What is existence?

That's complicated, but no, it's not literally a "ball"

The universe is expanding, which makes no sense. But (to keep it in line with my last analogy), think of it like a balloon. A balloon that never explodes (as far as we know). 

One thing that I'm curious about is what happens if you manage to reach the edge of the universe and keep going forward. It's physically impossible, since you would need to travel faster than the speed of light, but what if? According to Stephen Hawking (or what I understood from him, at least), you would just keep going around. Like the Earth, it doesn't have edges, so if you keep moving forward you would just keep going around the Earth.

Another problem is dimensions. Where is up or down in space? What is forward? The universe doesn't have a center (because every point works like a center. As in, if we say the Earth is the center, then the expansion started from the Earth. But some science stuff (radiation or something) proved that everywhere in the universe can be "the center")

But anyway, I'm looking at this in the scientific way! We exist for no reason and all at the same time. If we want to give ourselves significance, we will, but ultimately we don't have to. The universe will keep expanding, stars will die, civilizations will rise, regardless there being a reason.

... Why do you assume that the universe has an edge, or that it is finite, in any way?

Why do you think that  we need a center, up, down or forward?

Just imagine an infinite plane of little balls that repel each other.

I'm curious. If you travel faster than light, and reach a point in the universe where you can see the expansion happening, what would it look like?

The universe is finite. As finite as something infinitely expanding can be maybe the expansion will slow down, and contract in billions of years, but that's unlikely.
