Universe is finite or infinite?

Re: Universe is finite or infinite?

@Theorist

Read up on the shape called Torus. It will make sense then to say that the universe is expanding yet at the same time it is finite.

I wonder if that read answers the question that what is beyond that limit. even if universe is expanding at greater rate than we can travel but there must be a boundary then. What should be beyond that boundary? Nothing?
