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:-

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:-

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.

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:-

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.
