For decades mathematicians have searched for a specific pair of surfaces that can’t be transformed into each other in four-dimensional space. Now they’ve found them. In geometry and the closely ...

Physicists wonder if our universe contains hidden extra dimensions. These dimensions could explain why gravity is so weak. They might be curled up so tightly we cannot see them. High-energy particles ...

Yes, it is possible to create a three-dimensional image of a four-dimensional object: a hypercube is the four-dimensional analogue of a cube, and it has a well-known three-dimensional image that looks ...
