However, current theory says that the center
of the Sun (of every star) is the place where
the greatest amount of pressure exists. In
fact: It is at the center of every star that the
fusion that keeps a star "going" is taking
place--exactly because this is the region of
the highest amount of gravitational pressures!

Yes. This may well be due to the sun being made, not of magic ping-pong
balls, but of normal matter which, unlike said magic ping-pong balls,
are affected by forces other than gravity.

You are however, correct in surmising that gravitational forces in the
center of stars are negligible.

Or any other spherical body, for that matter. For a hollow
sphere, the gravition is zero anywhere within the hollow.
