Hello, recently I was listening to a radio talk given by Professor Brian Greene. I have always been able to understand him in his books, but on this particular occasion, he said something that I couldn't quite understand. He said that there is no edge to space, only an edge to time. If the universe is finite, how can it be that there is no edge to space. Is it that the universe curves over onto itself?
