By the way, It's irrelevant how much something weighs. A 1 kilo steel ball here on Earth will fall at the same rate as a 1000 kilo steel ball on Earth. If both balls dropped at the same time and from the same height, then they will both hit the ground at the same time.

Why?
BECAUSE THAT USELESS PIECE OF METAL IS NOT ABLE TO FLY.
WHO ARE YOU? I am serious here...what kind of useless nonsense can you be allowed to post?
OK....[deep breath....]
Well....as I said before, just to be PC, ANYONE can post his/her opinions, and that is understood. However, we would kindly ask that the posts be somewhat coherent. Please.
By the way...I used some Caps, and if I run afoul of the T&C, sorry...but I do try to refrain from using all Caps, unlike some posters who shall remain nameless.....
Kennedy said Americans had to go to the Moon to get supremacy above
Russians. But they were not able to develop that incredible technology
required to go there and faked all the story.
I also could say: I want two wings to fly.
But no one can give me them.
Your technology is poor. How is that you have hit a comet that runs fastest
in the deep universe but you haven't hit Saddam Palace with the first shot?
Haven't you got intelligent bombs?

are you serios, the lighter an object is the less speed it will have while falling, it's called kinetic energy, biger the mass more speed.
Try jumping with an extra 600 kilos weight on your back up and down and then do it with out it and see how far can you jump vericaly and in front of you, my 2 cents that you won't jump even a meeter.

This is really simple an stronaut weight on the moon was about 20 kilos .
A kid here on earth that has a weight of 20 kilos can not jump that way up and down.
You have argued that there is less gravity on the moon, I have already told you I already substracted the weight and calculated to the moon's gravity.
What I have said is that: 6 kilograms would act as 1 kilogram on the moon, that 1 kilogram on the moon would act as another object from earth that has 1 kilogram.
You have mentioned that acceleration is reduced , yes it's reduced from 6 kilograms to the behavior of how 1 kilogram in mass would act.
Take 2 rockets 1 50 kilos in weight and the other 10 kilos in weight
and give them the same propulsion sistem and see how far they go, I don't even know if the rocket that is 50 kilos in weight will even get of the ground.
Same with the astronauts they way they jumped up and down is unreal for 20 kilograms, you would argue that the weight of the astronauts is reduced due to gravity, but I already told you I substracted that and made them act like 20 kilograms.
SO what is your point soilent?
No offense intended, but to tell you the truth, I'm surprised you think a heavy object falls faster than a lighter one.
The concept that weight has nothing to do with the speed at which something falls is usually taught in basic science classes in school.
It has nothing to do with me being able to jump with 600 kilos on my back, and everything to do with the physics of falling objects.
Galileo (so the legend goes), and Giambattista Benedetti before him, each performed classic and legendary experiments that showed objects with different weights dropped from the same height will fall at the same speed.

109:42:42 Aldrin: Okay. I'm going to leave that one foot up there and both hands down to about the fourth rung up.
[Neil's photo AS11-40-5868 shows Buzz with one foot on the bottom rung and, as he says, his hands at the fourth rung.]

109:42:50 Armstrong: There you go.
109:42:53 Aldrin: Okay. Now I think I'll do the same (garbled) (Pause)
[Buzz tries to jump up to the bottom rung and doesn't quite make it on the first try.]
109:43:01 Armstrong: A little more. About another inch. (Pause)
[Buzz jumps up to the bottom rung.]
109:43:06 Armstrong: There, you've got it.
109:43:08 Aldrin: That's a good (last) step.

170:21:44 Young: We were gonna do a bunch of exercises that we had made up as the Lunar Olympics to show you what a guy could do on the Moon with a backpack on, but...
170:21:57 England: For a 380-pound guy, that's pretty good.
170:22:01 Young: They threw that out. Yeah, I jump flat-footed straight in the air, 300...
[In his book, Moonwalker, Duke said that, after John did a flat-footed jump, getting about four feet off the surface. "I decided to join in and made a big push off the moon, getting about four feet high. 'Wow!', I exclaimed. But as I straightened up, the weight of my backpack pulled me over backward. Now I was coming down on my back. I tried to correct myself but couldn't, and as my heart filled with fear I fell the four feet, hitting hard - right on my backpack. Panic! The thought that I'd die raced across my mind. It was the only time in our whole lunar stay that I had a real moment of panic and thought I had killed myself. The suit and backpack weren't designed to support a four-foot fall. Had the backpack broken or the suit split open, I would have lost my air. A rapid decompression, or as one friend calls it, a high-altitude hiss-out, and I would have been dead instantly. Fortunately, everything held together."]
170:22:08 Duke: About 4 feet. Wow!
170:22:14 Young: Charlie!
170:22:15 Duke: That ain't any fun, is it?
170:22:17 Young: That ain't very smart.
170:22:18 Duke: That ain't very smart. Well, I'm sorry about that.
170:22:23 Young: Right. Now we do have some work to do. (Pause)
Lunar Gaits
Armstrong, from the 1969 Technical Debrief - "I would say that balance (while walking) was not difficult; however, I did some fairly high jumps and found that there was a tendency to tip over backwards on a high jump. One time I came close to falling and decided that was enough of that."
...
On Apollo 16, Charlie Duke tried to jump as high as he possibly could and, as Neil almost did, tipped over backwards and landed on his PLSS. In his 1990 book, "Moonwalker", written with his wife Dotty, he said that, as he fell, he was genuinely afraid that he was about to die but, fortunately, neither his PLSS nor his suit was damaged and the only damage to himself was an acute case of embarrassment.

Going up.
Your view on acceleration in gravity is slowed down is invalid, only what go's up can have a decrese in speed, and because of that the astronauts jumping up on the moon can't preform what they did.
Going down.
Also the astronauts should come down like on earth, I don't think you understand me, it's the slow motion, there is no such thing, even in 0 gravity objects would move regular, they go down in slow motion, they should go down normaly, but they don't do they.

If you can't undesrstand that jumping up with more weight is harder then you are not very receptive.
In other words the astronauts movment should be like on earth, regarding weight to be more on spot, they can't go "up" the way they are doing it because gravity 1/6 would stop them and make them behave like a 20 kilogram object .
Weight does have a factor when going up, that you can be sure about, the more heavy you are the more dificult is to go up.
The best rebuttal to allegations of a "Moon Hoax," however, is common sense. Evidence that the Apollo program really happened is compelling: A dozen astronauts (laden with cameras) walked on the Moon between 1969 and 1972. Nine of them are still alive and can testify to their experience. They didn't return from the Moon empty-handed, either. Just as Columbus carried a few hundred natives back to Spain as evidence of his trip to the New World, Apollo astronauts brought 841 pounds of Moon rock home to Earth.
"Moon rocks are absolutely unique," says Dr. David McKay, Chief Scientist for Planetary Science and Exploration at NASA's Johnson Space Center (JSC). McKay is a member of the group that oversees the Lunar Sample Laboratory Facility at JSC where most of the Moon rocks are stored. "They differ from Earth rocks in many respects," he added.
"For example," explains Dr. Marc Norman, a lunar geologist at the University of Tasmania, "lunar samples have almost no water trapped in their crystal structure, and common substances such as clay minerals that are ubiquitous on Earth are totally absent in Moon rocks."
"We've found particles of fresh glass in Moon rocks that were produced by explosive volcanic activity and by meteorite impacts over 3 billion years ago," added Norman. "The presence of water on Earth rapidly breaks down such volcanic glass in only a few million years. These rocks must have come from the Moon!"
"Apollo moon rocks are peppered with tiny craters from meteoroid impacts," explains McKay. This could only happen to rocks from a planet with little or no atmosphere... like the Moon.
Meteoroids are nearly-microscopic specks of comet dust that fly through space at speeds often exceeding 50,000 mph -- ten times faster than a speeding bullet. They pack a considerable punch, but they're also extremely fragile. Meteoroids that strike Earth's atmosphere disintegrate in the rarefied air above our stratosphere. (Every now and then on a dark night you can see one -- they're called meteors.) But the Moon doesn't have an atmosphere to protect it. The tiny space bullets can plow directly into Moon rocks, forming miniature and unmistakable craters.
"There are plenty of museums, including the Smithsonian and others, where members of the public can touch and examine rocks from the Moon," says McKay. "You can see the little meteoroid craters for yourself."
Right: Nick-named "Big Muley," this 11.7 kg Moon rock was the largest returned to Earth by Apollo astronauts. One side of Big Muley was peppered with meteoroid "zap pits." Below right: A close-up view of 1 mm diameter zap pits shows tiny craters lined with black glass surrounded by a white halo of shocked rock.
Just as meteoroids constantly bombard the Moon so do cosmic rays, and they leave their fingerprints on Moon rocks, too. "There are isotopes in Moon rocks, isotopes we don't normally find on Earth, that were created by nuclear reactions with the highest-energy cosmic rays," says McKay. Earth is spared from such radiation by our protective atmosphere and magnetosphere.
Even if scientists wanted to make something like a Moon rock by, say, bombarding an Earth rock with high energy atomic nuclei, they couldn't. Earth's most powerful particle accelerators can't energize particles to match the most potent cosmic rays, which are themselves accelerated in supernova blastwaves and in the violent cores of galaxies.
Indeed, says McKay, faking a Moon rock well enough to hoodwink an international army of scientists might be more difficult than the Manhattan Project. "It would be easier to just go to the Moon and get one," he quipped.
And therein lies an original idea: Did NASA go to the Moon to collect props for a staged Moon landing? It's an interesting twist on the conspiracy theory that TV producers might consider for their next episode of the Moon Hoax.
"I have here in my office a 10-foot high stack of scientific books full of papers about the Apollo Moon rocks," added McKay. "Researchers in thousands of labs have examined Apollo Moon samples -- not a single paper challenges their origin! And these aren't all NASA employees, either. We've loaned samples to scientists in dozens of countries [who have no reason to cooperate in any hoax]."
Even Dr. Robert Park, Director of the Washington office of the American Physical Society and a noted critic of NASA's human space flight program, agrees with the space agency on this issue. "The body of physical evidence that humans did walk on the Moon is simply overwhelming."

Since no one can remake the particle hit it's clear the rock is from the moon, it also indicates that man could not come in direct contact with the rock, since it won't even come coser to our own particle generators that are high in radiation.

no, it indicates the rocks were on the moon for 3 billion years, and they took a lot of hits, while the apollo astronuats were there for a few days, and took a few less hits
