Paper 7 of the Holographic Cosmology Series. Derives Special and General Relativity from the unitarity of the 4-bit code. The gauge-gravity complementarity ΔG·k = 0 decomposes operators into spatial translation and internal mutation, yielding the Lorentz factor, time dilation, arrow of time, and the equivalence principle.
Khoa Nguyen (Fri,) studied this question.
