gravity is the same kind of radiation that light is - it's bound by the same speed - but whereas light travels through spacetime, gravity travels underneath or within the fabric of spacetime. gravity is a kind of ripple in spacetime, thus a mass will only affect another mass (gravitationally) when spacetime can ripple the distance between them - spacetime is pliant but not without resistance to mass - this resistance creates gravitation.

gravitational radiation and electromagnetic radiation are directly related. an object can only impress a certain amount of energy upon spacetime - directly related to its mass - thus more luminosity per mass means less gravitational mass. a star is so massive that it can emit large amounts of electromagnetic radiation and gravitational radiation but denser, darker stars will have more relative gravity because an equal amount of mass has more energy available to create gravitational radiation. that is, the more radiation given off in electromagnetic ripples the lighter a mass weighs on the fabric of spacetime.

gravitation is a consequence of the warping of spacetime due to a mass not being able to discharge it potential energy in the electromagnetic sphere. a black hole is the extreme situation where all of an object's mass/energy is devoted to gravitation because the electromagnetic radiation it sends out falls back of its own gravitation and fuels a fusion of radiation energy coalescing into infinite gravitational potential energy/infinite mass...
