One of the most entertaining accounts of this I know of is Fritz
Lieber's novel "The Wanderer", where the situation is complicated by the
appearance of an Earth-mass body near the Moon prompting one character
to exclaim "At last, a really challenging example of the three-body
problem"

Ah never mind. Never mind the drivel,

You're one post away from my kill file, and I'm being generous. You're
just another troll with a fake hotmail address posting via Google. Or a
complete idiot. Or both.

I want to know how the moon can drag a particle up from the earth
considering the masses and distances involved.

Gravity. Works over infinite distance, though it obeys an inverse square
law (tides obey an inverse cube law).

And why if it works on
volumes with very little gravity of their own, it doesn't have the same
effect on more imposing particulate.

Could you translate that into standard English?


Besides which, if the three body problem is in a constant state of flux
as one planet invokes movement on another, how does the distant planet
affect subdivisions of the other.

And another thing: If the moon can raise water on the earth, why can't
the earth raise sand on the moon? IIRC a crystal of silicon dioxide or
whatever sand is, is some 3 times more dense than water but the moon's
gravity is 1/6th.
I would have thought that on the theory most here are defending
(without the benefit of a schoolboy's primer may I add) the moon would
have tidal mountains and hills.


That's an odd way of putting it, but it does. If you took the trouble to
learn anything at all about the subject, you would find that the Moon's
shape is permanently deformed from a spherical shape. Look at
http://www.astronomycafe.net/qadir/q277.html for instance. Because the
Earth has 81 times the mass of the Moon it has not yet stopped rotating
relative to the Moon, so the bulge moves round the planet.
