      Our universe doesn’t have any physical boundaries – it isn’t limited, and exists everywhere and is approximately the same everywhere. The sort of boundary we could say exists would be related to the amount of the universe that is observable. If a part of the universe is too far away for light to have reached us, we can’t see it, so that would be a sort of visible boundary.

      Scientists believe we can travel in a straight line, end eventually return to the same place. They also say the universe is expanding. I like to think of it as a balloon we cannot get out of
