When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists have shown that in models of the Universe using any of the quantum theories of gravity there must also be a 'rainbow' of sorts, composed of different versions of spacetime. The mechanism predicts that instead of a single, common spacetime, particles of different energies essentially sense slightly modified versions thereof.
