Hello, first post here, I hope someone can help me with this.(adsbygoogle = window.adsbygoogle || []).push({});

While not having studied physics myself, I am reasonably familiar with many key topics, in this case I found myself thinking about the standard Big Bang model.

The question is simple - 'What is at the edge of the Universe'.

My understanding was that spacetime was curved such that the universe was 'closed' The result was that the universe had no edge and that if one travelled in one direction long enough, one would return to ones starting point.

This, I realised, can not be true though because such a universe would effectively be infinite (like being in a mirrored elavator) which would result in the Earths sky being as bright as the Sun from horizon to horizon as stated under Olbers paradox.

My gut feeling is that my understanding of what a closed universe is is flawed, but if not - what is at the edge of the universe?

Thanks in advance
