do you know the rationale with banning? Potential danger to other riders? It's interesting to me that it would be banned. Kind of like the first guy that went over backwards on the high jump, it seems like a legit innovation.

Also, the first dog being a Jack Russell Terrorist made it look too easy.

Mine had a 4' standing high jump. Made it look like levitation. Every landing on the table was like a boss.

Redneck Olympics high jump

When I was in high school a classmate had a high jump fail and his left hand could very well have touched his left elbow.

In this case, it is. Lift a 1 kg(mass) on earth 2 metres and drop it. If will hit the earth with a force of 9.8 Newtons. (F=m x a) That's its weight though we tend to use the kg instead of Newtons to express weight. To lift that mass, you would have to exert 9.8 newtons of force.

On the moon where acceleration due to gravity is 1/6 that of earth, that 1 kg mass would only weigh about 1.8 (9.8/6) Newtons. So it would take correspondingly less force to lift it.

So our astronaut should be able to easily push himself upright in theory.

The real reason he can't do it probably has more to do with the design of the suit (top heavy, not very flexible) and the loosely packed surface composition of the moon. Like trying to right yourself while wearing an inflatable sumo outfit in a McDonald's ballpit.

The high jump answer... when a high jumper clears 7 feet he is really just lifting his centre of gravity about 3-4 feet. He just twists his body horizontal to get his legs and feet over.

On the moon then, he would only lift his CofG about 18-24 feet (plus say 3 feet for his legs). So his record jump would be less impressive than you might intuitively think.

I have a degree in physics. I'm guessing that English is maybe a 2nd language for you? Your explanation of mass and weight is a little confusing. With regards to our astronaut on the moon, it's the difference in weight that matters. He should be able to (approximately) lift six times the weight he could on earth.
(Sidebar: It's often been said that Olympics on the moon would be fantastic because a man who could high-jump 7 feet high on earth would be able to high-jump 42 feet high (7x6) on the moon. In fact, he would only be able to jump about half that. Do you know why? I'll leave that with you as a challenge.)

Insofar as faked moon landings, I'm 90 % sure we went to the moon. However, bear in mind that Americans didn't know their own government was spying extensively on them til last year. It's the old joke... "Just because your paranoid, doesn't mean they aren't watching you..."

Alternative 3 is an interesting study of conspiracy dynamics. I first heard of it 30 years ago. It started as an April Fools joke in Britain on a science news TV show. It was brilliant in it's conception...

Short version:
1. Global warming will lead to total collapse of earth's eco-systems in two centuries or less.
2. Global governments are co-operating to move the cream of earth's leaders, scientists, etc to bases that have been established for decades on the far side of the moon and on Mars. (Alternative 3. Alternative 1 was huge underground bunkers, Alternative 2 was huge geo-synchronous cities... both were deemed too impractical to carry out.)
3. Mars is actually very liveable. We landed there in the 60s, established bases, using flying saucer technology developed here on earth by scientists.
4. The general population is being kept ignorant of the impending disaster, our advanced technology, the true state of Mars, etc. Governments worldwide are co-operating at the highest levels to perpetuate the myth that our progress in space is a slow, laborious process. (Which explains why the Soviet Union did not expose the Apollo programs as fake...) They don't want to cause a panic while they advance their agenda.
5. They have even developed psychic assassins capable of killing with their minds via spontaneous human combustion.

Due to TV schedule changes it was shown at a later date convincing the general public there that it was the real deal. (You can actually see the original show on YouTube... you'll even recognize some of the 'real scientists' etc as British character actors if you're old enough.)

It's a long convoluted story but thanks to a couple of follow up books and the Internet which gave it new life it has now 'morphed' into this vast conspiracy that involves alien / government co-operation at the highest levels à la X-Files. (The original conspiracy did not involve aliens...)

Adding to the fun and mystery is that some real world events -- too complicated to explain here -- later played right into details of the conspiracy.

I always thought it would make for a brilliant Hollywood movie -- the original version, not the 'updated' version.

That's great. How high are they jumping?

It looks like they're doing a Liu Kang flying kick from Mortal Kombat. I've never seen someone do the high jump like that.

I learned recently from some commercial on TV that before someone decided to start jumping over it backwards in the Olympics, people used to do the high jump facing sideways as if kind of stepping forward over it.

I remember reading about Kittinger's big jump; he lost pressure in his suit to one of his hands, which painfully swelled-up during his ascent (obviously he didn't abort... badass).


Also, another pressure suit failure blacked him out on a lower (but still insanely high) jump, and he only survived because an automatic parachute opened.

(... oh, this is covered pretty well in his wikipedia entry. http://en.wikipedia.org/wiki/Joseph_Kittinger#Project_Excelsior )

Apparently on the descent where he was blacked out he started spinning, and built up to 22g's of force on his extremities! Thanks wikipedia!

LMFAHS
"Acronym for "Laughing My Fucking AssHole Shut" typically used in Internet postings to express a response of great hilarity. A more advanced, powerful term than its predecessors LMAO and LMFAO, it should be used with care to prevent injury.
I was LMFAHS when my proctologist attempted to perform my colonoscopy. "

Also, as a side note, the acronym was coined by our very own Lucky760
