Thank God! I hate it when my conclusions
are flawed because of very complex reasons.

What you have done
is a rhetorical sleight-of-hand which,
like a good magician, gets us
looking in one direction while the action
is taking place in the other.

See: This is why there should be a law
against those TV programs that reveal how
the tricks of magicians like me are done.

You get everyone looking only at gravity
and missing the other forces at work.

That's in the other forces' work contract.

What you say about gravity is true: it is
greatest on the surface and
will cancel out -- be effectively zero -- in
the center. Pressure, otoh,
will be least on the surface and greatest
in the center.

You're thinking of a bowling ball there, friend:

Trust me: The Sun (and every other heavenly body)
is being shaped/worked by "something" other than
your laws of gravity. Go read all about it at:

The answer is PAINFULLY simple: It HAD to be,
otherwise IT COULDN'T BE--Even Einstein knew
this, when he said that "God does not play dice."
("Physicists have suggested that the laws and
constants of physics are too good - as if the
universe were set up to favour life's evolution.
It is as though there were, say, half a dozen dials
representing the major constants of physics. Each
of the dials could in principle be tuned to any of
a wide range of values. Almost all of these knob-
twiddlings would yield a universe in which life
would be impossible. Some universes would fizzle
out within the first picosecond. Others would
contain no elements heavier than hydrogen and
helium. In yet others, matter would never condense
into stars (and you need stars in order to forge
the elements of chemistry and hence life). You
can estimate the very low odds against the six
knobs all just happening to be correctly tuned,
and conclude that a divine knob-twiddler must have
been at work" IF you do not understand that the
sequence is not one of six disparate/unrelated
knobs but one of one leading INEVITABLY to
the next. In other words: The explanation to
Existence is always 1,2,3,4,5,6 ... inevitably.

If any other sequece is proposed the proposal is
as wrong as proposing your nephew created the
universe: No proof of that can ever be right. And
regardless how elegant the math may be.





How is that? Because the pressure is not
the result of gravity acting
directly on the ping-pong ball. It is the
result of gravity acting on
everything else.
At the surface, and at all points under the
surface until it gets to the
center, gravity is pulling the ball towards
the center. In fact, gravity
is pulling all the hydrogen (yes, helium
and other elements too -- but
vastly more hydrogen) toward the center.
Once at the center, gravity is
no longer effecting the ping-pong ball,
but it is still effecting the
trillions of trillions of trillions of tons
of hydrogen, all being
pulled, and generating pressure, toward
the center -- directly at the
hapless ping-pong ball. This exerts, as
could well be imagined, a good
deal of pressure on said ping-pong ball.

Read the theory of solar system creation:
All your atoms are experiencing a swirling,
NOT a rush towards center (you know, like
the orbiting planets, which are just merely
agglomerations of atoms).

The pressure towards center can NOT be
the result of gravity for an universe of
reasons (no pun intended).

For the reason why everything is always
moving towards center, go thou read it at:

You know, when the Ptolemy System was
drawn up... it all fit together perfectly. The
math was mavelus! Except, of course, that
a few "stars" (planets, actually, like Venus)
would suddenly seem to come to a dead stop,
and then go back the way they'd come!!!

But that was just a few planets--Why scrap
a beautiful system like Ptolemy's just for a few
lousy planets that refused to obey its laws?

Well, because it told you the system was rotten.

Well the system of Gravity we have today to
explain the way the universe works doesn't
just have a few wandering planets, it has
scientists losing their sanity and proposing
science fiction solutions at almost EVERY turn:

Time-travel (Yes: they're now quite SERIOUSLY
blaming the failure at CERN on "the notion that
the troubled collider is being sabotaged by its
own futu A pair of otherwise distinguished
physicists have suggested that the hypothesized
Higgs boson, which physicists hope to produce
with the collider, might be so abhorrent to nature
that its creation would ripple backward through
time and stop the collider before it could make
one, like a time traveler who goes back in time
to kill his grandfather.")... and a myriad other
idiotic physical impossibilities like "dark energy."

And yet these idiots refuse to accept that their
extire system is rotten. Believe Einstein on this
one: The solution is not 1, 483, 43, 9, 1999, 2
but 1, 2, 3, 4, 5, 6

Inevitability is ALWAYS the correct solution.





You can even perform a real-world experiment
to observe this principle,
using a real ping-pong ball and a swimming
pool. At the surface, there
is no pressure on the ball -- it floats there
quite happily. But cup
your hand over it and push it to the bottom
of the deep end. By the time
you get to the bottom of the pool, the ball
should be thoroughly
crushed. By gravity? No, the amount of
gravity pulling on the ball will
not have changed significantly from the top
of the pool to the bottom.
It was all that water on top of the ball
that generated the pressure. --Tomm Catt

I already tried this experiment on the SUN
itself, and burnt my hand--I suggest you try
thought experiments (if you're crazy enough
they'll all work out).

Your perfectly spherical sun and pingity-pongity ball remind me of a
joke I heard today.

A man buys a racing dog but soon discovers that the dog is slow. He
hires a vet to help him with the dog. The vet tells him "This dog is
just slow, there's nothing I can do."

Undaunted, the man tells the vet to "Hit the road!" and hires a
geneticist. The geneticist tells him "This dog is slow. I can help
you breed a faster dog but it will take many generations."

Not willing to wait that long, the man tells the geneticist to "Beat
it!" and travels to the nearest university to hire a physicist. Now,
the dog doesn't like to travel so the man brings with him videos of
the dog, several hours worth. He and the physicist watch the videos
intently. After the videos are finished, the man asks the physicist
"can you help me and my dog?"

The physicist scratches his beard thoughtfully, turns to the man, and
says ...... "Assume the dog is a sphere. ..."
