The intrinsic motions of light, time, and gravity are primordial forms (“drives”) of entropy, causing: 1) the creation, expansion, and cooling of space; 2) the creation, expansion, and aging of history; 3) the creation of historic spacetime, respectively. The charges of matter are the symmetry debts of light (Noether’s Theorem). Gravity pays the entropy-“interest” on matter’s symmetry debt by creating time from space – giving charge conservation an extended, causal significance in the time dimension. Light’s spatial entropy drive and expansion funds matter’s historical entropy drive and expansion, via the gravitational conversion of space to time; cosmic spatial expansion decelerates in consequence. Gravity pays the energy-“principal” of matter’s symmetry debt by the conversion of bound to free energy – via the nucleosynthetic pathway in stars, and via Hawking’s “quantum radiance” of black holes. The global gravitational field is reduced, as mass is converted to light; cosmic spatial expansion accelerates in consequence.
