A flash of light occurs in the middle of a vacuum on the surface of the Earth. The aether entrained by the Earth is at rest with respect to the Earth. You are in the vacuum moving towards the flash of light. You are moving with a relativistic velocity relative to the Earth. The light wave the flash makes reaches you. The light wave the flash makes has traveled at c with respect to the aether to reach you and the light wave the flash makes has traveled at 'c + your relativistic velocity relative to the Earth' relative to your relativistic velocity relative to the Earth. Factoring you in is the closing velocity with respect to the light. The fact remains the flash traveled at c with respect to the aether.

Since light in a vacuum moves at c relative to everything, it doesn't matter whether your aether exists or not. It moves at c relative to you, relative to me, relative to pink flying elephants and relative to the aether. So, let's do the math. My relativistic velocity is v, the light flash moves relative to "the aether" at c. So what is my velocity relative to the light as I approach it? Let's plug it into u = (v + w)/(1+ vw/c^2). v=v, w=c. u = (v+c)/(1+ vc/c^2) which is (v+c)/(1+v/c). Multiply by 1 in the form of c/c and we get c(v+c)/c(1+v/c) = c(v+c)/(c+v) = c. So, I measure the incoming light as moving at c, consistent with experiments, as well as what I said earlier (that light moves at c relative to everything). |
