False.

In classical physics, we'd expect that the relative speed of the tangential speed of Earth rotating into the Sun as the source of light with speed C would be W = C + V. And on the other side, as the spin is away from the Sunny side, we'd expect that W = C - V. But that did not happen when Michelson and Morley did their famous and ground breaking aether experiments.

What they found instead was W = C + V = C and W = C - V = C. This is important, the speed of light stayed at C no matter where the sunlight was coming from relative to their observations. How could this be?

And that's what Einstein set out to explain with his special theory of relativity. The bottom line here is that space and time adjust to keep the speed of light at C no matter what. That is space and time are the variables, while the speed of light is the constant. Who would have thought?
 
winds than when traveling in? Albert Michelson found that light waves travel slower perpendicular to the ether winds than when traveling in the same direction as the ether wind.

True or false?
