I've not admitted "perfect parabola", but only that the "dust rises to the height of the boot's bottom"..
Right then, we're done. Time up = time down.
My claim is that forces acted on this dust along the path -- such as an "adhesion effect" where it remained "stuck together" and also "stuck in the boot tread initially".. And the wake of a wide boot does provide a low-pressure zone that causes the air to move with it -- thus also eliminates some air resistance.
A whole lot of irrelevant bollocks. The nice little (didn't say perfect!) parabola is in independent flight. All physicists see this. If you don't, you aren't one. Besides, what physicist can't understand why it happens!
And then these forces stopped, and what did the sand do next??
The magic suction cup, the hyper-inflated pressure variation, the "effect of adhesion" which is certainly not a propelling force! It is an attractive force between molecules. In a rising clump of dust, it attracts molecules to those above and it attracts those above to those below.
Absolutely no way does any competent physicist suggest adhesion is a propelling force.
Answer: It Fell WAY FASTER than the astronaut's center of mass. Thus, a sign of fakery.
Is this what it boils down to? You are now acting like a troll. Ignoring virtually everything being addressed and repeating the lie.
and you say:
A great big lie - I haven't said that.
Even though it was close, moving upwards, and with no air to dissipate it - it dissiapated to invisible
Air doesn't dissipate it, kinetic energy in a chaotic process does that
you thought it was traveling in a parabola
It's proven and admitted. The parabola, independent flight rises to boot height in perfect synch. That tiny little parabola has got you by the gonads and as an HB you are scared to admit it.
So we disagree.
Your disagreement on the irrefutable means nothing.
I'd be glad to get a Physicist in here to weigh in. Without that -- WE ARE DONE with this point. Time to move on. This horse is long-dead.
Oh we are NOT done on this at all. You keep playing the HB coward. Besides you claimed to BE a physics expert - with your rude jibes.
All by itself, the little parabola in perfect sync - irrefutably - rises to level with Young's boots. Time up = time down. Your deceptive thread label about it falling too fast - disproven.
1. I provided you with 2 examples of this occurring on the beach - it has simply dispersed and hard to see against a same colour background.
2. You continue to ignore that there is a clear shadow moving away from Young in front of him.
3. You continue to ignore the slight but clear ground discolouration.
Then all this:
You also seem to be doing everything in your power to avoid the other points also:
Gene Cernan Bunny Hops
1. There is a nice parabolic arc of dust level with his boot. Time up = Time down.
2. Disipation is irrelevant grey on grey on poor grainy video.
3. We clearly see 3 impact areas on the ground for each of the last 3 jumps.
Dust Sideways kick
1. The height of this wave is just plain wrong for a little boot flick.
2. The distance requires >7m per second force with a sideways kick? That's ridiculous.
3. No dust suspension, no matter what you claim.
4. Adjusted for gravity without the unsubstantiated, unproven selective magic speed video, the astronauts look extremely unnatural.
