Is There a Fourth Dimension?

A fourth dimension is a family of axes that can move in any direction. Motion in the fourth dimension can be visible in your three dimensions, depending on your shape. In principle, if a for d person is in a three d prison, in principle, they could move through that fourth dimension, right and appear outside the prison cell. Rit: It's hard to think about because our brains are three de objects - we've been thinking about three dimensions for so long.
