Can someone give explanations or posssible debunk some of them?

Im absolutely floored right now by some of the videos. Most of them I have seen before, but some were just mind boggling at how the objects changed direction.
How can people be so ignorant and believe we are the only beings in the universe? I guess seeing really is believing these days. Too bad if one landed on some of these peoples lawns it still wouldnt change a thing.

You pose some really good arguments about thruster firing and such, but I have seen plenty of videos of thruster firings. Some of the clips in these videos are exactly that. But some are very, very intriguing. Usually when the thrusters fire it tends to move all the particles in the field of view. When you have a field of view with ninety nine percent stationary objects and then something comes zooming past while banging a ninety degree right turn right in front of you, it makes you wonder.

Thanks for the kind words.
You do highlight some of the visual phenomena which is really really eerie -- unearthly, in fact. The lack of uniform response by all particles to a thruster firing can only be understood in terms of depth -- the three dimensionality of the scene, a feature that is masked because without air there is no 'masking haze' effect as distance increases. Add to this that really close-in particles are often shielded by shuttle structure from the thruster effluent pulse. This is NOT an easy idea to get ground-trained eye/brain processors to handle -- it wasn't for me, and I later got lots of practice before it became "Obvious 2.0".

Now, denouncing ignorance is also a dangerous gimmick if you yourself show signs of it, so please also show some caution here. Normal motion of nearby shuttle particles includes frequence course changes in response to documented thruster firings.

Space junk, space debris, space waste — call it what you want, but just as junk and waste cause problems
here on Earth, in space spent booster stages, nuts and bolts from ISS construction, various accidental discards
such as spacesuit gloves and cameras, and fragments from exploded spacecraft could turn into a serious problem for
the future of spaceflight if actions to mitigate the threat are not taken now.
The European Space Operations Centre has put together some startling images highlighting this issue.
Above is a depiction of the trackable objects in orbit around Earth in low Earth orbit (LEO–the fuzzy cloud around Earth),
geostationary Earth orbit (GEO — farther out, approximately 35,786 km (22,240 miles) above Earth) and all points in between.
In 1961, the first explosion tripled the amount of trackable space debris. In the past decade, most operators have started employing on-board passive measures to eliminate latent sources of energy related to batteries, fuel tanks, propulsion systems and pyrotechnics. But this alone is insufficient. At present rates, in 20 or 30 years, collisions would exceed explosions as a source of new debris.
