Some scientists believe that with 'different energies' ( or wavelengths or frequencies) we can experience different worlds (or space-times).
David Icke writes that the universe consists of an infinite number of frequencies or dimensions of life that share the same space, just as television and radio frequencies do.
Icke believes that some people can tune their consciousness to other wavelengths, which is what psychic power consists of.

This means that particles with different energies will move in space-times and gravitational fields differently.
"Particles with different energies will actually see different space-times, different gravitational fields," Adel Awad of the Centre for Theoretical Physics at Zewail City of Science and Technology in Egypt told Scientific American.

Lee Smolin of the Perimeter Institute for Theoretical Physics in Ontario, says that rainbow gravity has been subsumed in a larger idea called relative locality.
Some people believe that our thoughts and emotions create our frequency.
