There's no dispute over the constancy of the speed of light when measured over a round trip. But what of its speed over a one-way trip?

If you had to pick one idea that is emblematic of 20th century physics, a good candidate would be the universal constancy of the speed of light. When Einstein put forward this notion in the special theory of relativity, it solved the long-standing mystery of why measurements did not show any variation in the speed of light with Earth's motion through space.
