Universe is finite or infinite?

Re: Universe is finite or infinite?

@ajazali

Atleast accept what you have posted.
From what we know, universe is flat. Rest is your personal liking and disliking or assumptions.
a closed manifold is a type of topological space, namely a compact manifold without boundary. In earlier post you said beyond the boundary is cosmic background. you are considering abstract objects as concrete objects.
Well i know you will lose you temper instead of clarifying these things.

Perhaps I should have rephrased that. The boundary isn’t really a boundary when it comes to Torus universe. I should have said something like it must be that the CMR seems like the boundary but it is not really a boundary. I am trying to answer your questions but I don’t know what in the world you are trying to do. Again, local universe being flat doesn’t have much to do with its shape. It’s flat as far as we know, we have theories about the unobservable universe. Since CMR seems evenly distributed, it’s likely that the rest of it is also flat but you can’t say if it’s finite or infinite.
