Here is a link to a net of a 4-dimensional 'hypercube'. I thaught for a minute and wondered how do we know there are more or less than 3 dimensions? How can we prove that things can exist in more or less than 3 dimensions. Take for example a 2D shape, lets say a square drawn on a piece of paper. That, when layed flat it still is a 3D shape. The hieght of the ink on the page. Also, how do we know there are 4 dimensions.

Above is a net of a 3D cube. It is 6 squares, which when folded make a cube. In the link, there are 8 cubes which in theory 'fold' together to make a 'hypercube'. How do we know this? Is it just made up, or has it been proved?
I hope you can answer this for me...
