Yes, I understand that Wang's experiment can measure linear velocity. But so what? You can measure linear velocity with a car's speedometer. Mine says 0 right now, shouldn't it say 1000 miles/hour? Wang's experiment only finds the relative velocity of the TX/RX with respect to the pulleys. The China-Japan experiment is rigid. It may be moving through space, but the transmitter/receiver are fixed relative to China and Japan.

But we did not detect it. What does this mean?


This means you put the wrong numbers into the equation.
