What Happened on the Moon Debunked - Part 7

Continuing Disk 1 of 2

Minute 118-120 We now move on to what I can only describe as a laughable contention from the film. This is where they suggest that a 10mph electric Lunar Rover should somehow produce huge "rooster tails" on Earth, because the footage we see on Apollo shows them and according to the film maker they aren't high enough!

The whole concept ignores the fundamental reason behind them being made in the first place, 1/6th gravity. On the Moon an object will have 1/6th the weight but the same mass. Now the Lunar Rover still needs to accelerate that mass to overcome inertia, but it has 1/6th the traction as on Earth. The actual mechanism involved to eject material from behind a vehicle also relies on the wheel spin speed. Whilst the wheel is in contact with the ground, there is less chance of the wheel obtaining enough speed to eject surface material, as there is when it rises (free of friction to accelerate). This is why most of the arcs are produced when it comes down after a bump in the terrain. The 1/6th gravity contributes quite significantly to the bouncing effect of the rover.

I have made a video debunking this section of the film:-

Minute 120-122 Percy starts the most famous clip from this film by making an incorrect statement. He says "astronauts moving in slow motion is another hallmark of the Apollo footage". This gives the viewer the idea that something has been slowed down.

Gravitational acceleration on the Moon will cause all objects to rise higher and for longer when even the slightest vertical movement is made. Together with less traction to move the 350lbs of mass, a restrictive suit has less traction to stop or change direction.

A short extract from a study explains this:-
http://www.ncbi.nlm.nih.gov/pubmed/9076966

"We investigated the effect of reduced gravity on the human walk-run gait transition speed and interpreted the results using an inverted-pendulum mechanical model.
We simulated reduced gravity using an apparatus that applied a nearly constant upward force at the center of mass, and the subjects walked and ran on a motorized treadmill. In the inverted pendulum model for walking, gravity provides the centripetal force needed to keep the pendulum in contact with the ground. The ratio of the centripetal and gravitational forces (mv2/L)/(mg) reduces to the dimensionless Froude number (v2/gL). Applying this model to a walking human, m is body mass, v is forward velocity, L is leg length and g is gravity. In normal gravity, humans and other bipeds with different leg lengths all choose to switch from a walk to a run at different absolute speeds but at approximately the same Froude number (0.5). We found that, at lower levels of gravity, the walk-run transition occurred at progressively slower absolute speeds but at approximately the same Froude number. This supports the hypothesis that the walk-run transition is triggered by the dynamics of an inverted-pendulum system."


We are told that astronauts never jump as high as they should do in 1/6th gravity, and later we are told they are on wires! Go figure that one out.

We are then treated to one of the worst examples of modern "special effects" by showing a man falling through some sort of wormhole suspended on wires. Bunkum.

I have already addressed some of this section:-

http://debunking-a-moron.blogspot.com/2011/06/gravity-and-motion-and-apollo-moon.html

Here is a video I made showing the sheer deception used by David Percy. The video shows how Percy has taken a small clip, deliberately avoided the sections either side of it, and made erroneous claims as to the motion sped up by 200% reflects Earth gravity.

Now, the obvious lens flare from Apollo 14 that is alleged to be a wire, and the "ping" on Apollo 17! The Apollo 14 clip is a very over exposed piece of footage. Everything about the shot shows this clearly. The "ping" occurs exactly where the radio antenna sits, and the secondary reflection is not vertical. It is the most obvious case of a lens flare you could get. Quite why they would need to use wires on Apollo 14 in the first place makes no sense. There is not an awful lot of activity from what I can recall.

The Apollo 17 clip is an internal reflection probably made during the copying process. It has no such anomaly on the original footage. The "ping" is in the shape of the reflection seen a split second before, from the radio antenna.

The section where he deals with the astronaut unable to jump high on the Moon, is a complete strawman argument. Here it is explained:-

http://www.youtube.com/watch?v=jxAz5OIzQsU

Percy continues by suggesting a "floaty effect" and a "dangly effect" of the John Young jump, then asks us to compare it with the Apollo gravity testing rig. I cannot fathom how somebody could suggest that a purpose built rig with sideways, vertical and forward stabilizers very clearly visible, could be compares to the mechanical motion from using thin wires. It is a ludicrous suggestion. Forwards and lateral mechanical motion would dimply be jerky and unresponsive due to the wire taking 5/6th (or whatever figure is claimed by hoax believers!) weight off of the astronauts.





















Percy shows a small clip from Apollo 16, where one astronaut helps the other astronaut up by pushing his hand. Since the astronaut weighs 60lbs, the idea that somebody could not do this is absurd. This is a fairly simple thing to do on Earth, where people are far heavier. Bunkum.

A video showing the Apollo 17 astronauts trying to jump up high and falling over (obscured a bit by the Lunar rover):-

Minute 122-124 Percy pads the film out here by waffling about how the film could have been altered to vary the speed. Since his theory about double speed is shot to pieces by watching any number of clips at double speed, this is just a means to reaffirm in the casual viewer, that his "analysis" was correct. He shows the John Young clip at double speed and tells us it looks like it was on Earth. No, it does not. His fall to the surface is still too slow for Earth gravity.

Here it is at correct Earth freefall speed, with absurd motion:-

Minute 124-127 We are now shown the hammer and feather experiment on the Moon, where the idea is suggested that it is very easy to fake. Then David Percy gives us firstly his "ahaa!" moment by showing the clip of "From the Earth to the Moon" where there is an edit! Followed by a doctored experiment of his own on Earth.

Here is a video showing more deception by him:-

http://www.youtube.com/watch?v=AXVMnA1Xp5Y

1. The Apollo experiment corresponds to Lunar gravity.
2. The Earth experiment does not correspond to Earth gravity!
3. The Earth hammer hits the fround first.
4. The feather on the Earth experiment is weighted and bounces!
5. The hand holding the feather on Earth is lower.
6. The Earth feather drops predominantly vertically.
7. The slowed down Earth footage does not correspond to Lunar gravity.
8. Footage of "From the Earth to the Moon" has an edit in their depiction.
9. The speeded up Apollo footage, at 200% and 150% does not equate to Earth gravity.
10. The speeded up clip looks bizarre and does not show normal motion.

Gravity and Motion and the Apollo Moon landings

Finding cherry picked motion differences between the first Apollo motion and a later Apollo mission is not a valid comparison, since there are fundamental differences between what the astronauts are doing, and why.

The Apollo 11 clip used, is where Buzz Aldrin is performing mobility tests on the Lunar surface. He is not attempting to do anything other than test how to move about on the Lunar surface. The camera used has a 10 frame per second rate, has fewer horizontal lines, and is black and white. On a first mission to the Moon, one would expect, by any stretch of the imagination, that the astronauts would be moving with a lot more care than later missions.

Comparing it to the last mission of Apollo, belies the fact that during the other missions, they were able to verify the safety and efficacy of the equipment and suits, were a bit more sure with their footing and were a little more adventurous as a result.

The clip used by most hoax believers(HBs) is the one that shows that very mobility test where Buzz Aldrin gently runs towards the camera. Sped up 200% the clip resembles Earth motion. I cannot deny that fact, though to a trained eye, his steps fall just a shade too slowly to the surface for Lunar gravity.
Now, here is a video that refutes the idea that speeded up footage of 200% was used on all missions (this claim was made by David Percy). The video includes a clip from Apollo 11, where Aldrin retrieves the Solar wind experiment and moves with absurd speed and body motion.

http://www.youtube.com/watch?v=JBICR4PTLfc

Now, since that video was placed on youtube, Cosmored has made allegations that it was incorrectly sped up and that subterfuge was used. This, despite refusing to verify the allegation by doing it himself.

I took it upon myself to do just that.

Here is the clip in question, normal speed 30.72 seconds:-

http://www.youtube.com/watch?v=njdQ0Y1Yyo8

Here is the clip in question, double speed 15.36 seconds:-
http://www.youtube.com/watch?v=Z1HvJ0WXkuo

That one clip makes a mockery of the doubled up speed contention.

I now present a series of videos to refute the ignorant contention that 150% motion was used with wires. Special invisble wires of course.

Video 1
http://www.youtube.com/watch?v=sq6yYQYoX_A

In this video, I show 3 objects being thrown. I determine the time from apex to surface and calculate the gravitational acceleration as equating to that of the Moon. I then calculate the necessary gravitational acceleration corresponding to speeding the clips up 150% and show that the gravitational accelerationis completely untenable for the heights and times relating to the 3 objects.

Question: Were inanimate objects on wires?
These objects do not correspond to Earth gravity when using your 150% theory!!


Video 2
http://www.youtube.com/watch?v=BKpZM0gqugs

Using this clip (watch?v=kibAjb6qjtQ) showing normal speed, I demonstrate the motion of a dust wave as being fully consistent with Lunar gravity. I show how a very accurate time was taken, and an equally accurate height. I demonstrate that the rise to apex time for your 150% theory is completely wrong. I further demonstrate that the distance the dust wave moves, has a truly preposterous initial velocity for Earth gravity from a sideways flick of the boot. I finally show the footage at speed that would make the rise to apex equate to Earth gravity (245%), that is ludicrous motion.

Question: Was the dust on wires?
The dust wave does not equate to Earth gravity when sped up 150%. A dust wave could not be kicked like that with a casual flick of the boot.


Video 3

http://www.youtube.com/watch?v=gD_O4pNnCQM

In this video I demonstrate Gene Cernan bunny hopping on the Moon, and take one of his jumps to show Lunar gravity. I slowed down the film to gain an accurate time. The result of the equation to change this to 150% is untenable.
Question:  Are you suggesting that Cernan, a few hundred yards away from the camera was indoors and wearing a wire?
Question:] Do you think a man on Earth could bunny hop those distances, travelling down a hill, with no arm movement to increase distance between jumps?


Video 4

http://www.youtube.com/watch?v=xSuvW0FRd-U

The idea that 150% was used for later missions is contradicting the theory of David Percy. You rely on him for that clip, yet disagree with him.

This video shows Cernan's "Hippity Hoppity" jumping sequence. Once again demonstrating consistency with Lunar motion. His natural forward motion is not impeded as his centre of gravity changes, indicating a complete absence of support. The video then shows that not only is David Percy's theory completely wrong, and to a trained eye, visually so....it also shows that a 150% theory is also wrong.

Question: If you maintain that non-visible wires were used, please account for an absence of retrograde motion always caused by them.

Question: How could anything track and match the distance he covered with a perfectly vertical wire?

John Young's jump has been exhaustively analysed. David Percy on the one hand says wire supports were used, then makes the observation that they never jump high enough!

David Percy is a deceptive businessman, and I have made a video showing a blatant example of this in video 5.


Video 5

http://www.youtube.com/watch?v=vawJhSnFcQ0

The video shows how Percy has taken a small clip, deliberately avoided the sections either side of it, and made erroneous claims as to the motion sped up 200% reflects Earth gravity.

Now, the obvious lens flare from Apollo 14 that is alleged to be a wire, and the "ping" on Apollo 17!
The Apollo 14 clip is a very over exposed piece of footage. Everything about the shot shows this clearly. The "ping" occurs exactly where the radio antenna sits, and the secondary reflection is not vertical. It is the most obvious case of a lens flare you could get. Quite why they would need to use wires on Apollo 14 in the fist place makes no sense. There is not an awful lot of activity from what I can recall.
The Apollo 17 clip is an internal reflection probably made during the copying process. It has no such anomaly on the original footage. The "ping" is in the shape of the reflection seen a split second before, from the radio antenna.


That is conclusive as proof could be, of the consistency of Lunar gravity, and the untenable position of speeded up footage.
