So I read a bit more last night and I found something that I definitely had to stop and think about. Famous mathematician Goerg Bernhard Riemann imagined a race of flatworms living on a piece of paper. Their entire world is two dimensional. But he questioned what would happen if someone crumpled the paper they lived on. The worms would get crumpled with the paper, and still see their world as two dimensional. However, if they tried to walk in a straight line, they would find themselves pushed by some unseen ‘force’- the folds in the paper.

Riemann suggests that things like gravity and other unseen ‘forces’ in our world could really be ‘crumples’ in other dimensions.
