These changed how I think about higher dimensions

The video explores the concept of 2D universes using games like Snake and Asteroids, explaining how these can be represented as squares and tori, respectively. It delves into higher dimensions, introducing 2D manifolds like the cylinder and Mobius strip, and explains the Klein bottle as a non-orientable surface. The video also covers the cartesian product of shapes, leading to the concept of 3D manifolds, such as the three torus, which are theorized to represent our universe.
