1. Stacked spins seem to violate the first law of motion, i.e. straight line motion; the theory that photons stack spins on collision because of not being able to exceed light speed in any single dimension seems inadequate, because it seems that the photon could only get hit from the front or side, which would not make it exceed light speed.

2. The UFT gravity equation analysis seems incomplete, because, if gravity is simple acceleration, while the charge field is a force, or pressure, it doesn't seem that a force or pressure can oppose an acceleration, as the acceleration requires a mass to have force. So I don't see how the UFT equation can have gravity taking just volume and be just acceleration, unless the volume turns it into a Force of L^4/T^4.
