Does space end?

Question

I am fascinated with the stars and space. Every night I wonder whatss out there. what do you think?

Answer 1

Space time is curved, so that if it were possible for you to fly at such a massive speed as to get to the "end" of the Universe, you would never be able to, as the curvature of space time would cause you to curve in your path, as well.

So, the Universe is, for all purposes, infinite.

Answer 2

Space doesn't end (at least astronomers don't think it does, and if it did, we wouldn't be able to reach the end since we can't travel faster than light.) The universe expands into a higher dimension. Also, space-time in our universe is flat (Not curved- things like black holes and other masses can make dents into space-time, but it is essentially  flat.) The universe has no edge and no center. Imagine it like walking on a sphere. Take earth for instance. What country is the center? China? Canada? None are! If the earth were an expanding balloon, you can see it as a 2-D surface expanding into the 3rd dimension. Our 3-D (4-D if you chose to include time) expands into a higher dimension as well. And like the surface of a sphere, there is no center and no edge.

Answer 3

well the theroy is that the universe is forever expanding, its difficult to fathom the distances im talking about, so    it dose and it dosent. it may end but moments later iwill expand, like when your blowing a bubble, except it never pops

Answer 4

well technically we dont know. but the theory is that it doesnt and it keeps expanding. or something along those lines.
