You got a star from me for that youtube link. If people still wanna waste their time on the tether incident, I guess it's their problem. The rest of us can concentrate on more important things now

'fly' to a spot near the tether and remain at a .5 sec stand still and THEN shoot from a standstill in space and launch in the opposite direction....as the EC stated.. in a delta-V direction...

notice the trajectory. now imagine a particle following it exactly - it appears to move in one direction, slow down, and make a complete U-turn.
now imagine yourself positioned *exactly* in line with the direction of its motion. it will appear to move, slow down, come to a complete stop for a moment, and reverse its course 180 degrees exactly.

BingoThanks for noticing that. Seems some people do still think

Also the "earth gravity pulling them down" has one other SERIOUS flaw...
TIME
There is no way that the gravity of the Earth would effect a small particle (as claimed) in such a short observable time frame. If that was true then there would be no problem with orbiting debris as it all would fall down in a matter of minutes (the time span of the observed movement in the clip)
As we all know this is not the case as even heavier objects stay in orbit a very long time, especially at the height of the Shuttle orbit.
To even suggest that the Earth's gravity is pulling these in a parabolic trajectory back to earth is ludicrous. Glad someone sees through the attempted obfuscation.
And as you say the effect would be EQUAL on all the objects, not be random in several directions

the force of gravity is effecting *everything* in the earth's gravitational field, at ALL times (there is no wait and then hey gravity grabbed me). both the satellite and the shuttle were previously in orbit with the earth, which means their trajectory and velocity exactly match the earth's curvature, so the earth pulls them "down" at the same rate the earth is "falling away" as they shoot into space.
see spaceplace.nasa.gov...
anything that breaks off of the shuttle or satellite shares its momentum. as there is no atmosphere in the earth's orbit, there are no forces slowing it down so it moves alongside the shuttle / satellite, with slightly different directions resulting from the forces that broke it off of the object it was a part of. SLOWLY, these little bits of difference in trajectory decay or change their orbits until they are so far away they can no longer be seen, or they fall into the atmosphere. they also collide with each other and the shuttle, drastically changing their direction of movement.
here's an experiment that should demonstrate momentum very simply and effectively.
grab a small ball, such as a baseball. hold it in your hand facing downwards and jump, and while you are rising into the air let go (but do not put any force into this, just "drop" it). it should move with you perfectly, staying in contact with your palm until your feet hit the ground and it continues along its path to the ground.
now do the same with an *extremely* soft nudge away from you. notice how it still follows your exact up and down motion, but it also drifts off to the side while falling.

OK, but can you demonstrate that gravity could account for that degree of movement in that time frame on any object, regardless of size?

OK, thanks for going to that effort. However, what accounts for that force appearing to suddenly kick in on these "objects" (whatever they are). The force of gravity would be operating on them all the time, right? So why do they appear to move in one direction and then suddenly, abruptly change direction? And why do only some do so and not others? Why do we not see a general drift on all "objects" in frame, all in the same direction, constantly, in accord with a constant force?
