heres a question i have for those who think the moon cannot have an atmosphere (or that its not possible)
if the moon has enough gravity to collect millions of tons of rocks, why would it not have enough gravity to collect a little bit of gas ?

according to the alleged moon gravity and atmosphere; Since my vert. on earth is 27 inches, If i were on the moon, I would have a more than a 52.38 inch vert. jump. That means if i jumped strait up and did not bend my legs; there would be more than 4 and a half feet between my heels and the ground. The astronauts aren't getting anywhere close to this in the videos. They're actually not even close to half as high.
Either the videos are fake, the suites are in excess of 300 lbs, the astronauts are in extremely poor shape, OR the data we've been given in regards to the moons atmosphere and gravity is inaccurate.

However, with that said, Newtons law of gravity is tremendously accurate, more than enough to calculate the moon's gravitational pull, more than 99.9% correct in fact. Certainly good enough to calculate a neutral point.

It's just a pointless waste of time to try to "debate" anybody in a thread like this. It's overrun by people who have never cracked a physics book or had a physics class, but rather get their education and information from a lot of dubious sources, science fiction, and fuzzy-headed crackpots who also have a poor understanding of basic, commonly-accepted physics.
And then we have to get into the whole mess of how there's a huge conspiracy among the scientific community to maintain the status quo, and how the real truth is only known to a courageous handful of visionaries (crackpots) who are denied a fair hearing.
What a snooze festival. The best thing to do is just try to be amused and if the crap flows a little too heavily, bail out and go do something else. I've never seen it do any good at all to keep beating one's head against the brick wall of ignorance and stupidity.

Wow, you seem to have a god like perception to know everyones qualification. Why not share your greater knowledge so we can all be enlightened, or was your comment made as you state, out of "ignorance and stupidity" ?

Discuss the topic.
Thank you.

It's easy to tell if the Moon has an atmosphere - just watch it occlude a star.
(Unless you're John Lear who, on my pointing this out to him, proceeded to claim only the 'dark side' of the Moon has an atmosphere! )
"The Moon seems to have a tenuous atmosphere of moving dust particles," Stubbs explains. "We use the word 'fountain' to evoke the idea of a drinking fountain: the arc of water coming out of the spout looks static, but we know the water molecules are in motion." In the same way, individual bits of moondust are constantly leaping up from and falling back to the Moon's surface, giving rise to a "dust atmosphere" that looks static but is composed of dust particles in constant motion.
Astronauts need to know, because in the years ahead NASA plans to send people back to the Moon, and deep dark craters are places where they might find pockets of frozen water--a crucial resource for any colony. Will they also encounter swarms of electric dust?
