Anything you have said, I've addressed with logic about how things SHOULD perform in freefall.
Except, as has already been explained, your ideas about how things 'should' behave in freefall are oversimplified and wrong. You've had physicists and others tell you this, but still you won't get it, will you?
And OK, a few seconds of video hardly makes a convincing rebuttal, since none of thiose astronauts were doing anything at all resembling the kind of thing the guy on Shenzhou 7 was doing.
I still await your pointing to the exact time in the Shenzhou 7 vide where the taikonaut's legs move suspcioously, as requested some time ago.
