Default The Ping-Pong Ball and The Sun / S D Rodrian

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...

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.


As the inverse square of the distance between the two centers of
mass.

[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.]


No. The sun is not a homogeneous body with depth, nor is the Earth,

Terrestrial gee increases with depth to 50% radius

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.


BULL****

[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.]


You are ignorant at best, and most likely stupid.

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).

Conclusions from the above
thought experiment:

There is either a huge cavity at the center
of the Sun,

[snip rest of crap]

Stupid confirmed. What of the weight of the overlying strata?
