Hey guys, I'm new here but I've been reading all this stuff and still haven't seen anyone address a concern I have always had with the whole subject. So it may sound niave of me to ask but I'm gonna throw it out there and hope one of you "experts" will chime in and give me a definitive answer to my query.......IF we did actually go to the moon and the flag was put there, then WHY does the video of it show the flag moving as if wind current is moving it around? I was always under the impression that there is no wind or atmosphere for that matter on the moon, so how could the flag move the way it does in the video????
I'll thank you in advance for any clarity that may occur.

EarthSongs,
I think you'll get an abundance of answers and referrals to the many, many times this very old issue was discussed in the past.
Perhaps a summary of the situation will suffice to explain. That, combined with some due diligence on your part, searching within these two massive threads we've had for any and all information you might want (in detail) on the subject:
Essentially,
The flag moves only because it is being moved...by the men setting it up.
That is the sole reason why a flag moves. Because it's being moved. There's nothing magic about vacuum that prohibits an object being put in motion from moving. The men take a step and they move. They twist the flag pole, and the flag sways, not because of wind, but because they move it. Gravity helps too.
That's it. Simple physics. No mystery to it alt all!
Hope it helps you some!
Another question to ask yourself is this:
As you watch the Apollo 11 EVA video...or any Apollo TV coverage....you'll see long sections where the flag is visible (especially on Apollo 11 where it was in the single static camera field the whole time).
You'll also note that no matter what happens, that flag never, ever moves..save where you see the men touching it during set up.
It never moves for simple reasons:
there nothing there to move it. No one, no matter how close they pass to the flag, move it unless they touch it.
For hours, we all watched that flag sit there unmoving.
It was on the Moon, in a vacuum.
