These very strange universes could theoretically be possible

The video explores the concept of wrap around effects in 2D and 3D universes, using examples like the game of asteroids and a 3-torus. It discusses how light behaves in these universes, creating the illusion of infinite space. The video also delves into different geometries of the universe, including flat, spherical, and hyperbolic spaces, and introduces Euclidean three manifolds. It concludes by considering the possibility of non-flat universes and their implications on light and perception.
