aether has been used in various gravitational theories as a medium to help explain gravitation and what causes it. it was used in one of sir isaac newton's first published theories of gravitation, "philosophiæ naturalis principia mathematica" (the "principia"). he based the whole description of planetary motions on a theoretical law of dynamic interactions. he renounced standing attempts at accounting for this particular form of interaction between distant bodies by introducing a mechanism of propagation through an intervening medium. he calls this intervening medium aether. in his aether model, newton describes aether as a medium that "flows" continually downward toward the earth's surface and is partially absorbed and partially diffused. this "circulation" of aether is what he associated the force of gravity with to help explain the action of gravity in a non-mechanical fashion. this theory described different aether densities, creating an aether density gradient. his theory also explains that aether was dense within objects and rare without them. as particles of denser aether interacted with the rare aether they were attracted back to the dense aether much like cooling vapors of water are attracted back to each other to form water. in the "principia" he attempts to explain the elasticity and movement of aether by relating aether to his static model of fluids. this elastic interaction is what caused the pull of gravity to take place, according to this early theory, and allowed an explanation for action at a distance instead of action through direct contact. newton also explained this changing rarity and density of aether in his letter to robert boyle in 1679. he illustrated aether and its field around objects in this letter as well and used this as a way to inform robert boyle about his theory. although newton eventually changed his theory of gravitation to one involving force and the laws of motion, his starting point for the modern understanding and explanation of gravity came from his original aether model on gravitation.

rainbow gravity (or "gravity's rainbow") 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. 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. 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. 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. scientists are currently attempting to detect rainbow gravity using the large hadron collider.
