 It is obvious that if it moves from left to right, transversely, or from right to left, the speed of light will be the same.
 Let's say that I have not measured it yet, that I just know that it is very fast, so I cannot say precisely what it is.
 But AT LEAST, can I suppose that it would be very surprising if it moved faster in one direction or another. Which would be an absurdity in a concept of refutation of absolute or privileged referent.
 If I can measure this transverse speed from A to B (i.e. without possible Doppler effect that could distort my measurement) I will find Vo=3.10^8m/s.
 And then, it's true, if I practice in the other direction, I will still find
Vo=3.10^8m/s.
 It is equal in both directions, and it is logical that it should be.
 I will now turn my device AB by 90°, and I will place myself this time, in a position perpendicular to what I was previously, and again, I will calculate the transverse speed of light from A to B.
 Bingo!
  From A to B, or from B to A, I will note Vo=3.10^8m/s
 Tears of joy will then slowly flow down my pink cheek:
I have just proven something invariant.
 Except that I am an idiot who has not understood anything at all, and who has not noticed the enormous bias that I have just described here.
 

What are you babbling about?
It is thoroughly experimentally verified that the speed of light
is isotropic, constant and invariant.
The number c = 299792458 m/s follows from the definition of the units.
Only an ignorant moron would claim:
"the speed of light depends on the position of the observer."
