Why can’t we move between dimensional planes?

383 views

I get the idea of dimensions of reality and how there are eg infinite two dimensional planes in our 3d one. What I don’t get is why they can’t be moved between. In a 3d cube we can draw a 2d line between any two points by changing the direction.

Applying this to reality, if we exist in a universe with more than 3 dimensions, why are we unable to change the “direction” we are in?

I’ve often heard extra dimensions described as planes but why can we not change planes in the same way a diagonal line would. Is it because the concept of a higher dimensional direction doesn’t exist in our lower dimension?

We live in 3 dimensions. In theory, there could be infinite ike you say but we can only perceive our own dimension, and those lower. If we moved into the “2nd dimension” we would no longer perceive our current dimension and thus we could not move back.

More simply, our 3 dimensions are height, width, and depth. To move dimensions we’d need to remove one of these from ourselves which ofcourse is impossible for obvious reasons.
