this makes no sense, since for c=1, *_a_c^2_is_still_1_*, whereas for a
*_c=3e5_km/s_a_c^2_is_something_else_*. You are crossing
*_the_Russian_red_lines_* you may not trespass.

Measurement suggests light has its own speed in space.
The atom can move toward or away from light by its speed.
If one has absolute speed; and they compete; so does the other.
What is the proof things don't have their own absolute
speeds?
