For the first time ever, two quantum experiments have proven the existence of a fourth spatial dimension. Scientists in the United States and Europe were able to show that not only is there a conventional three-dimensional axis of space where objects can move, but there is also a fourth spatial dimension that could change our entire concept of motion.

The two quantum experiments involved the Hall effect, when an electron is restricted to two dimensions. When scientists subject the electron with high magnetic fields at low temperatures, they witness the Hall effect, where electrons move in pre-determined topological pathways.

As a result, electrical current is only able to flow along the material’s edges. While the discovery doesn’t have any useful applications yet, it opens up an entirely new area of study, allowing researchers greater insight into string theory that could expand our understanding of dimensions beyond the 3D world we’re confined to.
