Rainbow gravity (or "gravity's rainbow"[1]) is a theory that different wavelengths of light experience different gravity levels and are separated in the same way that a prism splits white light into the rainbow.[2] This phenomenon would be imperceptible in areas of relatively low gravity, such as Earth, but would be significant in areas of extremely high gravity, such as a black hole.[3] As such the theory claims to disprove that the universe has a beginning or Big Bang, as the big bang theory calls for all wavelengths of light to be impacted by gravity to the same extent.[4] The theory was first proposed in 2003 by physicists Lee Smolin and João Magueijo, and claims to bridge the gap between general relativity and quantum mechanics.[4] Scientists are currently attempting to detect rainbow gravity using the Large Hadron Collider.[5]
