Light moves at C and is invarient

I do not say this work is pro or con for an Aether If there is an Aether we probably can never detect it. If there is not an aether, so what? Light can still move through space.

What can turn a beam of light that is moving as fast as allowed. To turn would imply the light accelerates and that is not allowed. Eddingtons studies are questionable as he had something to gain by supporting Einstein.
