Michelson-Morley 2

Verify by calculation that the result of the Michelson-Morley experiment places an upper
limit on Earth’s speed relative to the ether of about 5 km/s.

Because M-M found that N must be less than or equal to 0.01, then his places a maximum velocity limit on this calculation:
Showing the limit mathematically by solving for v with the given information:
The numeric calculation for the above formula is 4.91 km/s

Because the Earth rotates at approximately a rate of 30 km/s, and because the velocity above is much smaller, our calculations imply that the "ether" does not exist. Meaning, there is no preferred reference frame.
