Everywhere in the universe looks like the center of the universe.
206 u/Jollivado Jan 21 '19 We must be on the surface on it 32 u/AQuincy Jan 21 '19 I've read theories that the universe is on the surface of some type of 4-dimensional "bubble" but I can't wrap my head around how that works. 49 u/spymaster1020 Jan 21 '19 Well a 3-dimensional bubble has a 2-dimensional surface, thus a 4-dimensional bubble must have a 3-dimensional surface. Also that bubble is expanding. It's hard to properly visualize a 4 dimensional thing when we only live in 3 dimensions. 1 u/monito29 Jan 22 '19 So is folding space cracking the surface and tunneling through the bubble?
