Question: What is at the end of the universe?

Elizabeth Pearson answered on 11 Mar 2012:

A very good question. One we will most likely never know. There are some theories that there is no ‘edge’, that space curves on itself so if you kept going in a straight line for long enough you’d end up back where you started. Other people think that there’s just nothing for ever and ever. It’s questions like that that made me want to become a scientist.
