Has anyone estimated dimensions of universe? or is it endless?

Question

personal views are also welcome... thank u

Answer 1

I think the universe is endless. If it were not (it has dimensions), then outside of the universe's dimensions what kind of "space" and "matter" are in there? If it is not outer-outer space, what is it?  

Answer 2

To my point of view, our universe was born 15 billion years ago, and by now, it should be approx. 30 billion light years across.  That's what I learned about.  But we obviously do not know for sure.  

Answer 3

i think it is endless . if we did somehow reach the edge of the universe what would we see? would it be like a giant bubble?

some scientists think that the universe will expand to the point where it will tear itself appart .

others think that at one stage it will stop going out and come back to where it came from .

Answer 4

The universe is endless; constantly expanding.
