i was reading Einstein's dreams just now, and in it it states that light is the fastest thing, nothing can go faster. And so i thought about the expanding universe, a galaxy in particular; if there is an edge to the universe, this galaxy is there. So perhaps nothing is on the other side because light, and nothing else for that matter, has gotten there yet. However, i can imagine what is there. If i knew much about the universe, i could imagine it nearly perfect even. So how does one explain the fact that faster than the speed of light, from earth, i have seen the other side of the universe where nothing exists.
