  1. It's a completely abstract dimension... "imaginary" if you'd like to call it that. We can infer it exists based on the laws and principles of math, but we can't know it exists because our dumb brains can only see in 2D and infer 3D based on context. Sort of like evolution... We can infer it exists based on evidence that we've found, but we can't know for sure because none of us can live long enough to watch other species grow and die enough times to adapt. Except that the 4th dimension is even more abstract.
