Answer: false
Explanation:
Hi, The Michelson-Morley experiment was designed to measure the extra time it took a light beam to travel "there-and-back" against the ether wind, compared to a light beam travelling "sideways across" the ether wind.
The experiment failed, there was no variation, and years later Einstein explained that there is no ether. Light is a special sort of wave which requires no medium to carry it.
