[After saying gravity doesn't exist in vacuums, and someone points out the moon has gravity]
There is air on the moon.

Air on the moon? Really? Well, then, too bad you didn't happen to mention that to the NASA scientists who spent all that time working on perfecting the spacesuits for the astronauts who went there. That would have saved them an awful lot of trouble.
>>Why even bother pointing out that the moon has gravity? Hasn't this guy ever heard of, I don't know, THE SUN?<<
Wow - anybody care to tell him every single subatomic particle has a gravitational force, it's just so incredibly insignificant you need trillions of trillions of trillions of them to notice a collective force.
Before judging the site, read it. The site is dedicated to debunking christianity and god by simpling looking at common sense. Because of the successful nature in which it points out flaws in religion it has begun to attract more and more fundies.http://www.whydoesgodhateamputees.com/god1.htm
It seems WITNESS has made a few errors including 'on' for 'in' and, and this is especially egregious, mispelling 'my head' as 'the moon'. And people say there's nothing wrong wih education these days.
Bodhitharta, please tell me you're not serious. The few gas molecules that happen to drift near the moon's surface in no way constitute anything contiguous enough to constitute an atmosphere, breathable or otherwise.
The moon is not a vacuum. Gravity on the moon is 1/6th of the earths gravity.

>>Yes, there is enough gravity on the moon to have some atmosphere.<<
American Geophysical Union
>>An intensive effort is underway to determine the composition of the Moon's tenuous atmosphere. Although conventional wisdom says the Moon is devoid of atmosphere, and in layman's terms this may be close enough to the truth, the space just above the lunar surface is not a total vacuum.<<
So, in other words, you're playing semantics. The moon's atmosphere is so minimal that it hardly merits the term. It's certainly insufficient for us to survive (for one, the composition is apparently entirely different than on Earth) without a space-suit.
Well, technically, in a vacuum there is no gravity, because there is nothing in said vacuum to attract to other things in the vacuum. The reason why things in a vacuum(technically this makes it not a vacuum any more, as it is no longer devoid of matter) fall is because they are being acted upon by earth's gravity. However, the presence of air is definitly NOT a prerequisite to the existence of gravity. Things fall to the moon because the moon is included in the system, making it not a vacuum. Also, all definitions of "air" I can find, define it as the air on earth or specifically:

<<air
First of all, I dispute the definition of vacuum which WITNESS THE REAL uses. Every definition of vacuum I've seen involves a pressure of less than 1 atmosphere, but only a handful say anything about a vacuum necessarily being devoid of any matter.

If you define the word "air" in the human sense as in what we breathe, there is no air on the moon (wrong gases in the wrong proportions and densities). If you define the word "atmosphere" in its literal sense as a gaseous spherical layer around a celestial body, yes, the moon has an atmosphere, however nebulous. We just can't breathe it. Accepting that the moon does have an atmosphere, we then accept that there are molecules for gravity to act upon. As David D.G. correctly pointed out, in a hard vacuum, there is indeed gravity, there's just nothing for the gravity to act upon. Another problem now arises: Ask Schrödinger,,, if we place anything in the vacuum to measure it, it is no longer a vacuum and hence the measurement is meaningless.
No.
Gravity doesn't exist away from MASS.
Mass generates gravity. Gravity attracts mass. Matter has mass. "Air" is matter, therefore air has mass. Ergo, "air" goes where the gravity is. Gravity attracts air.
This is why Earth has air. The moon ALSO has an atmosphere, because it has SOME gravity, but it's billions of times thinner than Earth's.
Your explanation is analogous to claiming that the waving of trees generates wind.
You know, I think that given WITNESS THE REAL's tendency to completely redefine words, I wouldn't be surprised to discover that his/her handle means (in ordinary English) UNSEE THE IMAGINARY or DON'T LOOK AT FANTASY or ALIENS CHEESE KITTENS THERMODYNAMICS.
