Perhaps you have seen c+v and c-v in the equations at the beginning
of

http://www.fourmilab.ch/etexts/einstein/specrel/www/
� 3. Theory of the Transformation of Co-ordinates and Times from a
Stationary System to another System in Uniform Motion of Translation
Relatively to the Former

There c+v and c-v VALIDLY follow from Einstein's 1905 false light
postulate (c'=c) so logically (but not physically) the equations are
correct, although Einstein presents them in an incomprehensible way.
If one wishes to replace the false light postulate with the true
equation c'=c+v given by Newton's emission theory of light, then
everywhere in Einstein's equations c+v becomes c and c-v also becomes
c and one obtains

tau = t, instead of Einstein's equation tau = a(t - (v/(c^2 - v^2))x')

You are only looking at the math, you will not see the simplistic beauty
of c+v until you study Algol and Mira.

Why did Einstein say
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,
the "time" each way is the same?
