Then the length traveled changes for two photons emitted when they cross the starting line at different velocities:
const d = distance = 1
# d_start = 0
# d_finish = d
c: Velocity # of a photon in a vacuum
v1: Velocity # of photon emission source 1
v2: Velocity # of photon emission source 2
v1 + c != v2 + c
distance / (v1 + c) ?= distance / (v2 + c)
((v1 + c)*t) - ((v2+c)*t) ?!= 0
Should (v + c) be prematurely reduced to just (c), with a confirmed universal expansion rate?
