(...) Let's do the math. Assume light travels at a constant velocity c in the ether. Suppose the apparatus is moving through the stationary ether with velocity v. In the direction of motion, the time for the light to reach the mirror and come back is T=L/(c-v)+L/(c+v). In the direction perpendicular to the motion, the time to reach the mirror and come back is calculated by solving (cT)^2=L^2+(vT)^2, so T=(L^2/(c^2-v^2))^(1/2). The experimental results did not match this calculation. Instead T was the same for both directions (T=2L/c )." >
Maybe you are not so good in math, Pentcho, but on the very next line, which you left out, we have:
"The conclusion of the Michelson-Morley experiment was that the speed of light was a constant c in any inertial frame."
