Paper V of the Brane-Bulk Series Mass as Focal Deceleration of the Expanding Brane B. D. Jagadeesan, MD

Rest mass is the focal deceleration εH(x, t) of the expanding 4D brane caused by bulk non-uniformities inherited from the parent black holes. The focal zone is not a static depression but a standing wave in a river of continuously arriving brane material persistent because the deceleration is re-enacted on each new element. Gravity is the brane current carrying other masses toward the deceleration sink. E = mc2 is derived as the kinetic energy of brane material arriving at speed c and decelerating to rest. The Planck constant h = ℓP ·mP ·c is the minimum phase-space area of the brane geometry the minimum action of one complete brane oscillation cycle. E = hν follows because a photon executes ν Planck-scale brane cycles per second at cost h per cycle. Light carries δH = 0: it is not in spacetime but is spacetime propagating. The brane oscillates at the Planck frequency νP = mP c2/h ≈1043 Hz; all observable light is low-frequency resonance of this underlying Planck oscillation.
