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...

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.

  [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.]

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, 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.

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!

 These are two self-excluding viewpoints:

One of them can be correct while the other
one is not. But both of them cannot be
correct at the same time: Either gravity exists
AND the center of the Sun (of every star) is
hollow. Or fusion DOES indeed take place
at the center of the stars because the center
of every star is its region of maximun
pressure--and therefore the effect of
gravity is "somehow" negated/voided
inside the stars.                               *

* Of course, once The Great Thinkers
(who once thought the world was flat,
that the universe revolved around the
Earth, that Dark Matter and Dark Energy
explained the observable deficiencies
of gravity, that the entire universe
erupted from a magic bean, and that
it was constructed of vibrating strings
tuned into existence by unimaginably
tiny mathematicians)... once The Great
Thinkers think on this self-contradiction
awhile I'm sure they will be able to
come up with any number of their usual
outrageously reality-denying/logic-
twisting solutions to this puzzle.

... when they could just visit:
http://physics.sdrodrian.com

And WHY have none of them even
thought about this self-contradiction
(when it's so impertinently obvious)...?

Well, because we teach our so-called
Great Thinkers to learn by rote: "2times3
is33...2times4is104...4times5is55..."
and so on. And we not only require
that they do not challenge the validity
of what we are "teaching them" but
we actually demand that they accept it
all as The Indisputable Truth Eternal:

Can you imagine what would happen
if when the Great Professor is mumbling
"7times3is859..." to his class a student
were to get up and exclaim: "Professor,
you, sir, are an ignorant baboon: 7 X 3
is 21." Now: What grade do you believe
such a mere student would get? And
what student does not understand this?

By the way: The dramatization above is
an exaggeration for purposes of illustration
only. [This disclaimer is always required
when addressing former students of all
such universities, I'm sorry to say. SDR]

Ah! O well ...

Meanwhile, understand this: Newton
had no idea whatsoever what made the Sun
(or any star) burn the way they did/do/does:

It was not until around Einstein's time that
astrophysicists would at last able to put together
a cohesive theory of how the Sun is able to
ignite and sustain a self-perpetuating fusion
furnace--and all the data says that this is only
possible at the most central portion of the core:
there just isn't enough pressure outside it to
bring matter close enough together to produce
the required sustained fusion. Look it up.

The problem, of course, is that all the theories
of gravity produce NOT the greatest pressure
at the Sun's (and any other star's) core but a
great big hollow (or, at the least, a horrific
decrease of the gravitational "concentration
of matter" required to "push it/bring it together"
close enough for fusion to occur!!!!!!!!!!!!!!!

Newton never gave this a thought (it never
troubled him in the least that his theories of
gravity said that the Sun could not possibly
be working--turned ON--) for the simple
reason that he did not KNOW that the Sun
worked by means of nuclear FUSION and
that the only way nuclear fusion can be
produced inside the Sun is if the greatest
(not the least, but the highest) possible
pressures are concentrated at the Sun's core.

Had he known this, it would have blown
his mind--until he went on the Internet, of
course, and visited:

http://physics.sdrodrian.com

learning there, from Mister Rodrian, the
correct way in which the universe works.

It would not have changed his theories of
motion/gravity. It would simply have made
them actual. Hoorah!

Newton "conveniently" leaves out the
matter of "pressures" at that center, just
as exactly what gravity might be was
something he knew was beyond his field
of knowledge:

If you propose that there is ANY pressure
at all at the Sun's center, then you will
need to explain where such pressure
comes from... considering that the "left
inner wall surface" [of my proposed
hollow at the Sun's center] is under MORE
gravitational pull from the left wall than
from the right wall (on the other side of
that hollow): There may be as much mass
in the right wall as in the left wall, yes,
but the mass of the left wall is obviously
closer to the "left inner wall surface."

You may stuff as much mass as you
like at the Sun's center--just explain
the mechanism which does the "stuffing."

For what's the use of merely noting one
has spotted a phenomenon--without also
attempting to explain it, when explaining
phenomena is the highest aim of science.

  NOTE: Einstein's mind was of a clever
  but lazy nature, thereby (the moronic
  mathematical fudge factor so-called
  "cosmological constant"). You have
  to understand that relativity only
  describes gravity in the way it is seen
  to work; Einstein too never goes so far
  as to even try to explain by what means
  it might be working. And so it remains.
  [The so-called "graviton" is merely a
  theoretical proposal ... it is a physical
  impossibility, but it's the only thing
  they have--It is in Einstein's mind that
  it is a physical impossibility because it
  would require instantaneous action
  at impossible distances, a problem
  which itself drove Einstein to come up
  with gravity as a strictly geometrical
  description instead of a "real" (physical)
  solution as might be provided by a
  possible graviton. Like Newton, Einstein
  recognized that explaining what gravity
  actually was... was quite beyond his field
  of knowledge.]

Today we can see the problems of lacking
a real/actual understanding of what gravity
actually is when everywhere we look gravity
seems to misbehave; The galaxies do not
behave as if they were perfectly observing
the laws of gravity (acording to which they
should all be flying apart). Not to mention
the problem of the Sun & the Ping-Pong ball.

Actually no: I imagined that, according to
Newton, once it reached the exact center
of the Sun it struck an identical ping-pong
ball coming at it with the same force (where
they both magically combined into a single
bigger ping-pong ball). I'm used to dealing
with these questions: When I told my little
nephew the story of Pinocchio he seemed
much more interested in knowing WHY the
toy-maker had made him with a bellows-
mechanism for talking; How did he know
Pinocchio was going to be doing any talking!

Gee, I wonder why--

Any particular reason why not?

You seem to know this. And yet it eludes you
that my post is all about challenging you to tell me
where that "high enough" pressure is coming from!

Another Pinocchio explanation required.

You also missed the fact that the highest
gravitational pull "down" is NOT at the
surface of a sphere but a little bit up from
it (since at the surface part of that pull
will be defrayed from the sphere's sides).

Yes it is, if I so command it: This being a
thought experiment of mine, I can make of it
anything I wish. Even a giraffe. Live with it.

Read my post again: It's about this ping-pong
ball slowly making its way there. Albeit, I
don't recall saying it started having sex once
it got there: You made that part up.

I made it up: Now it exists! That was easy.

Not if my magic is strong enough. And
I have VERY nice thoughts--My magic is
therefore unstoppable! [Frankly, I don't
believe you've quite grasped the concept
of "magic."]

I take it you have spent a lot of time
plunging magic ping-pong balls into your
sink then: May I suggest a girl-friend.
She'll smack you up the side of yer head:
Fix'ya right up.

All right now, I knew this is where I'd
eventually end up: Listen up! Once there
was a toy maker named Geppetto ...
