I have no expertise in this area, other than rudimentary concepts. The following might apply if the visualization of space, as depicted below, represents actual reality, but I don't know for sure. Please help me understand better, you guys!
2-dimensional space
The curvatures deform into the 3rd dimension, as can be seen in the picture below.
So in 3-dimensional space, what does space deform into? 4th!?
We can't even visualize it! Unless it doesn't deform into the 4th, but instead just stretches space, without a deformation into a 4th. See another picture below.
This is mentioned by Brian Greene, notable for his documentary The Elegant Universe. He's mostly about string theory but poses this question as well.
