What lies beyond Universe? What is Universe expanding into?

>> No.11729194

Imagine the universe is the surface of a balloon. When you fill the balloon with air every point on the surface of the balloon becomes further from every other point on the surface of the balloon. Now the surface of a balloon is two dimensional but the universe is 3 dimensional so imagine the universe is the surface of a four dimensional object that's expanding.

More universe, then more spacetime bubbles separated by inflating areas, then it all loops back on itself on largest scales.
