There can be no perfect balances of forces. Lets go with gravity
and angular motion of the solar system. With great luck objects are
captured and find a mutual gravity point and revolve around each other.
Earth Sun,and Earth Moon . We think are in perfect balance. Not so.
There was a spacetime when the Moon was only 25,000 miles away. Now that
is 10 times closer than it is today. What that tells me is the energy
of angular motion is slightly stronger than gravity. That lots of stuff
was much closer to each other,and the solar system had more density. Now
with lesser density stuff is moving away from each other at a faster
rate.(Gravity weakens with distance) Lets take this idea all
the way out to our 10th planet. It is 3 times further from the Sun than
Pluto and it circles the Sun. However when we can take very accurate
distance we will find over time it is moving away from the Sun at a very
noticeable rate. What is my post telling? Its that structures in
orbit are making their orbits larger as I type. Solar systems are losing
density,and growing larger. Galaxies the same thing. The universe the
same thing. The Macro world is growing in size,and loosing density.
This begs the question. Is the micro world doing relatively the same
thing? Bert

Say, Beert, could it just be that the moon, over the past 4B years, acting
as Earth's vacuum cleaner, has accumulated a whole lot of space debris, thus
adding to its overall mass and increasing its centrifugal escape force to
the point where it recedes at 2.7 cm (or is it inches?) annually. You say
"what about the Earth"?? Well, most of the debris entering the Earth's
gravitational grasp will eventually burn up, upon entry of the atmosphere,
greatly reducing the amount of mass actually making it to the surface.

On the other hand, Mars at one time had 4 moons, two of which have already
spiraled into the planet and one of the two remaining ones is due to follow
in a few million years, a blink of the eye, in geological terms.

The latest calculations indicate that Mercury is on a slow drift towards the
Sun. However, the movement is so minute, that it'll never get there.
Rather, the Sun will reach it first, when it starts expanding outwards on
its way to Red Giant status, in about 5 - 6 B years hence.
