The Ping-Pong Ball and The Sun.

[A mind experiment--Therefore, if
you do not have a mind, forget it.]

Imagine a magical ping-pong ball
which is only affected by gravity.
That is its only quality. (Therefore
it can travel inside the Sun without
being destroyed.) Now...

OK Got it.

This ping-pong ball is approaching
the surface of the Sun. As it does so
the pull of the Sun's gravity gradually
increases on the ping-pong ball.

[When it is at the Sun's surface,
the pull of the Sun's gravity on
the ping-pong ball will be at its
maximum.]

The instant the ping-pong ball plunges
past the surface of the Sun, the pull of
the Sun's gravity on the ping-pong ball
will begin to decrease.

OK

[This is because as the ping-pong ball
travels closer and closer to the center
of the Sun: the mass pulling on the
ping-pong ball is decreasing, all the time
that there will be a growing amount of
Sun-mass behind it pulling back on it.]

OK

Once the ping-pong ball reaches the center
of the Sun it will achieve gravity equilibrium
and lie forever suspended there (at the exact
center of a great hollow).

Assuming no momentum effects then yes but were the heck did the big hollow
come from???

Conclusions from the above
thought experiment:

There is either a huge cavity at the center
of the Sun, or certainly a cavernous region
therein where there isn't as much Sun-
matter as there must be surrounding it.
According to the current laws of gravity.

Not a conclusion at all. You have a complete non-sequitur there. Nothing you
said leads to a hollow. What holds the hollow in place? what prevents the
sun's mass from collapsing into the void given that every particle that has
mass will attract every other particle with mass until they reach an
equilibium?
