Nothing from NASA says the moon is hollow.  Get over it.

The moon would have a horrid time staying in a consistent orbit around

the

earth and sun if it was hollow.

It would also have a horrid time exerting the very precisely calculated
gravity that it has; you know, the one that creates tides and stops
moon-walking astronauts tumbling away towards Alpha Centauri?

I can't believe people would entertain this gobbledeegook.

And I can't believe that you do not understand physics, where if a moon
is applying a force on the earth and dragging the tides, as the moon

rotates,

then an equal force should be applied to the moon, making it spin on its
planetary axis. But it does not, and hence, no magnetosphere. And hence
you are full of beans.

Earthling.

What the hell was that?
Sounded a helluva lot like common sense flying out the window and smashing
against the pavement.  Yep, there it is, all the way down there on the
sidewalk next to logic and reason.

Planetary Physics 101:
Magnetospheres have NOTHING (I repeat NOTHING) to do with Gravity.
Absolutely not one thing.  They are two completely and utterly different
concepts.  That's like comparing an ocean to an atmosphere.
Gravity is the force exerted by all mass on all other mass.
A Magnetosphere is a protective magnetic shield formed around a large planet
(and only ones with a large metallic core, such as Earth), which both
contains electrically charged upper-atmospheric particles, and repels
dangerous ions that stream out from the sun in the form of Solar Wind.
Go to a dandy little site called www.google.com and enter "magnetosphere"
and check out the top three sites.  You may want to do that before replying.

The Moon DOES rotate.  It rotates at precisely 1 revolution on its axis per
orbit of the earth; hence we always see the same side.  If it didn't rotate
at all, then observers on earth would see a constantly changing side of the
moon, and there would be no concept called the "dark side" of the moon.  Not
a hard concept to grasp.  I think they teach that in grade 2 or 3 now.

And finally, the moon's rotation has absolutely nothing to do with tides,
it's the moon's GRAVITY that drags the tides.  If the moon was spinning at
18rpm the tides would be no different than they are now.  Of course the moon
would explode, and we'd all be made extinct as the pieces came crashing back
to earth, and then we'd have no moon and no tides at all, but that's not the
point.

If the moon were hollow then a LOOOOONG time ago someone would have
calculated that based on it's diameter and its gravity it had a density of
something like styrofoam.  And that would have raised some very serious
questions long before today.

Hope that helped.
