Im not really smart like the people who most likely will be answering this question so please try and stay on a "layman" level ok. I just watched a vid that says: 0D is a point which cannot move has no lenght or width. 1D is a line can move left/right has lenght but no width. 2D is like a square can move left/right/up/down (anywhere in between) and has lenght/width. 3D everything mentioned before except it had depth and can move forward/back. Once he (guy in video) got to 4D all he said was: hypercube, has height, width, depth.......and thats it. I want to know what "upgrades" this 4D has unlike the rest.
