Is space endless?
I was having a debate with someone about this and we were thinking, something can't just go on forever, for everything must come to an end, doesn't it? But then again, how could the universe itself end? It can't just end, and there be nothing. There would have to be something past everything, for nothing does not exist. So I'm pretty stumped, is it? Is it not? Explain your answer as much as possible please.
