The Five Dimensions of General Relativity

Colusa extends Einstein's theory of gravity into five dimensions and just like that, electromagnetism pops right out. In 1926, a Swedish theoretical physicist Oscar Klein kind of built on Colusa's 5D theory, trying to make a quantum version of this theory. This extra dimension could only hold particles with very small wavelengths, which means very high energies. So after all in quantum mechanics, all objects, all particles, everything are waves.
