..... these people love their pseudoscience.....not that, if the spin of the earth can't be measured, then it is simply not spinning.... but instead, if the spin of the earth can't be measured, then it's not even a concept, it's a meaningless data point.  And they think this with a straight face. 

If the earth was spinning, it would be very very easy to prove.  The reason they haven't proven it, is because it's simply not true, it can't be proven, if it were true, there would be plenty of evidence.  Like with flat earth, there's plenty of evidence to prove this is the case, but you gotta stop listening to the propaganda.
