The edge of the Universe is one of the greatest mysteries in modern science. What would happen if we could travel beyond it? Could we reach the farthest edges of space, or is there even an “edge” to ...

The edge of that is the place beyond which light hasn’t had time to reach us since the beginning of the universe.

The edge of the Universe, as it appears to us, is unique to our perspective; we can see back 13.8 billion years in time in all directions, a situation that depends on the spacetime location of the ...
