hmmm I had not been aware of the null hypothesis. What do you mean by "friction"? In Experiment 1 I show that these gyro rising experiments are only possible with as little base friction as possible. And in Experiments 5, 6, and 7, I perform these tests on an ice block and they rise while also behaving massless: https://mes.fm/experiments-playlist

I'm also not aware of Quantized Inertia. But my gyro experiments prove that "inertia" itself as a distinct property of mass does not exist; as gyros precess with no angular momentum (see Experiment 4) or centripetal/centrifugal force; and hence no inertia.

I'm not big on theory but in #AntiGravity Part 6 I allude to a possible explanation and which has to do with (true) magnetism and the virtually unknown concept of "counterspace".

Also check out Experiment 9 for one of the most amazing demonstrations ever done...
