We can recreate a 3-dimensional picture on a 2-dimensional surface. Why can’t we visualize a 4-dimensional world in a 3-dimensional area?

Answer 1

The only reason we can properly understand the 2D representation of a 3D object is because we live in a 3D world, so we have a reference point. We’ve never experienced 4D.

That doesn’t stop us from trying though. If you google tesseract you’ll find 3D representations of a 4D object (or, rather 2D representations of the 3D representations, since you’re looking at a 2D screen).
