[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.
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?

You're going to have to cite here.
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:
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!

Cite? That somebody didn't prove something, and its not true?
If you really don't believe that the acceleration due to gravity can increase as you move closer to the centre of the sphere, and what I say is wrong, I can easily produce a counter example.
OTOH, many other posters have also pointed this out, and I believe that one even provided a link which shows the value of g actually increases for a period of time as you go further underground on the earth, which shows the earth itself is a counter-example to the assertion that the force of gravity always decreases as you go close to the centre.
The underlying reason is that as you descend, there is a smaller amount of mass in the sphere "underneath" you, but you are closer to the centre so by 1/r^2 the force is greater. Which one of these dominates depends upon the mass distribution by depth. As many (most) objects have increasing density with depth, its quite plausible that many or most of these objects have the characteristic that the maximum gravity is not on the surface, but "underground".

No. You're going to have to cite on how my "magical ping-pong ball which is only affected by gravity" behaves otherwise than how I described it does in my post. Please do.
You, and other posters, obviously do not believe in magic. And for your benefit I then provided a way for my "magical ping-pong ball which is only affected by gravity" to stop at the center of the Sun's Great Hollow:

As I have already told you, the ping-pong ball will oscillate about the sun's centre.

Of course "surface of the sun" is not such a clear concept, things change gradually.

The Sun-mass behind it is effectively canceled. If we assume the Sun rotational symmetric, we can simply ignore the complete shell outside the current position of the ping pong ball.

By inertia, it would travel on. But at least there would be no accelaration at the center. In fact the ping pong ball has gained more and more speed on its way to the center (though at a slower and slower rate).

Erm, no. The first conclusion is that particles move faster and faster the deeper inside the sun they are (just like the ping pong ball was fastest at the center of the sun). Since the particles don't just stubbornly move towards the center (that would look like the sun becoming a black hole), we conclude that the temperature gets higher and higher the deeper we go, and is highest at the center.

The existence of gravity does not imply that the center is hollow (far from that).

It is precidsely the effect of gravity that causes high pressure and high temperature in the center. Your thought experiment shows that the temperature is high, and there must be pressure to "keep out" all those ping pong balls falling towards the center

It depends on whether he can prove 7 X 3 = 21 on the basis of the axioms. Let me tell you, 7 x 3 = 21 *can* be proved on the basis of the usual axioms. Thus that student should be applauded

Admittedly, Kelvin calculated how long the sun could burn if it where made of coal. But that is unrelated to the question of gravitational pressure singulariteis at the center.

Since there is no hollow at the center, Newton's argument is still valid for rotational symmetric aggregations of gas under gravitationl and thermal equilibrium (thus it at least holds without correction for energy released in fusion if there is none, e.g. for a giant gas planet - thes have high pressure as well in the center).

There is no exceptionally high density at the center, the density is fairly smooth, at least there is no singularity.

Obviously the ping-pong ball overwhelmed the fragile minds of many of the posters here (I only used it as strictly a focusing device, but far far too many poor souls here were simply dumbfounded by a ping-pong ball inside the Sun and wrecked their brains over how it was reacting in there). And this in spite of my warning then that if they didn't have a mind they ought not try to work their way through my [sic.] "mind" experiment. Forget the ping-pong ball guys: I only chose it, instead of a golf ball, say, because it (too) most ironically is hollow. Now, consider, instead:
Superman and The Sun Experiment.
[A thought experiment--further simplified now for those who just cannot get past the ping-pong ball of the original experiment.]
NOTE: This is happening in an universe in which gravity behaves as everybody thinks it does (Newton, Einstein, & you):
And, why Superman? Because not only is Superman immune to gravity, while still able to feel it (we've often seen him just floating about in many of his movies but we've never seen him floating away every time he closes his eyes)... but he is also actually strengthened by the rays of our yellow Sun--Therefore he actually becomes most superest of all INSIDE the Sun!
The problem, of course was: getting a hold of him. Luckily I knew where Lois Lane worked and gave her a ring, in exchange for which she quickly agreed to help me meet him (Superman--By the way, his name is Super Man not "Joey Superman" or other, it's just that he's not uppity and never insists he be called MISTER Man): I very quickly explained the nature of my experiment to Super Man, and he agreed to undertake to travel to the center of the Sun for the sake of those poor souls who would never grasp the meaning/purpose of this thought experiment because they had been struck dumb by the only thing they were able to see from that instant onwards, namely the bouncing ping- pong ball.
--Your announcer is Mr. Maxwell Smart:
BEGIN THOUGHT EXPERIMENT
Now: Imagine Superman approaching the surface of the Sun.
As he does so he feels the pull of the Sun's gravity gradually increasing.
[When he is at the Sun's surface, or pretty near it, Superman will feel the pull of the Sun's gravity to be at its maximum.]
The instant Superman plunges past the surface of the Sun, he will feel the pull of the Sun's gravity begin to decrease. And it will continue to decrease as he flies towards the Sun's center.
[This is because as Superman travels closer and closer to the center of the Sun: the amount of Sun mass pulling on him is decreasing, all the time that there will be a growing amount of Sun- mass behind him pulling back on his super body. We can set aside the Sun mass to the sides, but we must still subtract it from the "pulling" mass.]
Once Superman reaches the center of the Sun he will feel either no gravity there (or very little if any); and, if he so wishes, he can lie there forever just floating about impervious to all INCLUDING gravity (at the exact center of a great hollow which the laws of gravity tell us will be found thereabouts because most of the matter at the center of the Sun will have been "pulled" away from its center [there may remain a single hydrogen atom at the exact gravitational center of this hollow... but certainly during 5 billion years of "pulling" most other atoms will have been pulled aside because they could NOT also be at the exact gravitational center unless they were one system, of course. If there is a perfect hollow it is because its "left inner wall surface" 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 of The Great Hollow as in the left wall of The Great Hollow, yes, but the mass of the left wall of The Great Hollow is obviously closer to the "left inner wall surface" [to quote a certain Mr. Rodrian].
Or Superman can, as he did, leave the inside of the Sun to report on his findings. I am sure that many posters here would have wanted me to ask Superman why he wears his yellowing underwear on the outside of his pants and neat-o stuff like that--but he suddenly had to fly off, as he saw that Lois, in reaching for an aspirin, had swallowed a suicide pill she was doing a story on instead and died. Now Superman would have to travel back in time a couple of hours to save her... yet again! [Thank you Mister Smart.]
END THOUGHT EXPERIMENT
Now, what are the implications of this thought experiment? [Hint: They have nothing whatever to do with Superman, and, nor with Lois Lane either.]
1. From the size of the Sun brainiacs've calculated that the only place in it where there's enough gravitational pressure to produce fusion is in a relatively compact central core. Most of the Sun is just plasma so loosely flying about that it's hard for enough matter to be brought close enough for atoms & stuff like that to smash together in order to sustain a fusion chain-reaction.
2. The only method brainiacs know of to produce the required pressures is if gravity is trying to push all the mass of the Sun into its very core.
3. And yet, as illustrated by Superman's voyage, the very laws of gravity tell us that once you start getting closer and closer to such a central core, the gravitational pressure should steadily decrease rather than increase: a very substantial mass of the Sun ought to be moving away from its central core.
Now, most posters here will probably wish to know if I asked Super Man for his autograph or something like that. But, not for those posters but, for those persons with a mind, some very deeply fundamental questions about reality will now have to be addressed:
1. Is the Sun the result of gravity, as we have heretofore understood gravity?
2. Obviously there exists the required pressure at the Sun's core for fusion to occur, or the Sun would not be ON.
3. How does that pressure come to be, if the laws of gravity as we understand them tell us it ought not exist there!
This is certainly a self-contradiction the existence of which is telling us something very profound about the nature of how we understand reality (apparently we are misunderstanding it somewhere/somehow).
CONTINUANCE:
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 maximum 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.
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?

Fred: The entire universe just changed and you missed it because you were too busy watching a ping-pong ball oscillating!

Your mistake is obvious. Yes, the gravity at the center of the Sun is weak, so the matter in the center of the Sun doesn't *add* very much to the pressure there.
But that doesn't in any way change the pressure placed on the center of the Sun by the mass in the regions of the Sun further out, where the gravity is pulling it in.
Pressure is transmitted by the characteristics of the fluid material of which the Sun is made. The transmission of pressure has nothing to do with gravity.
If I take a 100 pound iron weight and put it on top of a piece of plastic foam, will it make sense for me to say, "oh, well, the foam is a very light substance, so there isn't much gravity on it, so there won't be pressure there"? No. The foam won't add much to the pressure from the iron weight, but that doesn't diminish the pressure applied by the iron weight.

Please STOP RIGHT THERE: don't repeat the nonsense you wrote (which I paraphrased perhaps with too much sarcasm), Follow the consequences of gravity acting on Superman as he approaches the center of the Sun (NOT in reality BUT as the laws of gravity would have it be):
The Sun is not solid but a plasma ball. This means it can expand (or contract) as much as it needs to in order to accommodate behaving as the laws of gravity say it ought to behave:
This means that every particle in it is free to move to its region of the greatest gravitational field strength from its region of lowest gravitational field strength (even in its core, which may be 10 times denser than lead, but is still a plasma).
Are you suggesting that every one such particle will move to the area of the least gravitational field strength from the area of the highest gravitational field strength? That's the whole point of this series of posts right there.
There is no question that the Sun works exactly as we all believe it does and that the highest pressure exists at its core (I just told you how much pressure there is there producing a density 10 times greater than that of lead).
The question to consider is NOT how the SUN actually behaves, but how would a plasma ball like the Sun behave were it indeed obeying the classically delineated laws of gravity (that say the strength of gravity acting on a body descending to its center decreases. Do you understand now?
I guess it's true: no one understands sarcasm.
A solid ball may convey pressures from one point to others, but a plasma ball like the Sun would (were it only under the design of gravity alone) eventually describe in space the field(s) of gravity acting upon it ... exactly like iron filings describe the fields of a magnet acting on them.
And then you would have to "see" its mass (the equivalent of the magnet's iron filings) describing a "more massive" shell around a "less massive" center.
We don't see that (in fact, it is a physical impossibility because then the Sun would not be ON).

I see nothing wrong with the statement "while he is getting closer to the center of the Sun his distance from the center of the Sun decreases!" If you think it wrong, you seem to think that while he is getting closer to the center of the Sun his distance from the center of the Sun increases or at least stays the same - weird.

There is only little difference between "in reality" and "as [Newton's] laws of gravity would have it be".

You should also add the laws of thermodynamics. Or treat the plasma as ideal gas without interaction between particles, i.e each is travelling on a smooth curve around the center (the curve would be elliptic if the mass were all concentrated at the center, but , alas, the sun looks more complicated than a point-mass, so these curves look more complicated).

... and away from there again - while "falling down" the particle acquires kinetic energy and hence will plunge out again. Typically it will have transversal movement in the first place, hence not "hit" the centre exactly but rather whirl around it to be slingshot out again to higher levels.

"Exactly" like that. Of course not absolutely exactly since the laws of physics we know are always only approximations (e.g. general relativity may add a bit correction to Newton (and is still only a better approximation), non-linear effects should be considered, electromagnetics, asymmetry, external influences exist, equilibrium is not attained and of course the plasma is not an ideal gas - in fact, if there really were no interactions between hydrogen nuclei, there would be no fusion!). But the model still good enough to predict high density and high pressure and high temperature at the core.

Eventually. That is, when the particles have come to a "rest" (aka. the plasma has cooled down). And yes, in that case the particles would settle down in the center where gravity pulls them to. However, in that case the particle are so close together that we may no longer approximate them as points. We need quantum physics here, but what we get is a neutron star. If you insist on looking at "gravity alone", you just have to look at a very massive star that will overcome the nuclear forces and then the mass will indeed fall completely to the center and create a black hole.

Unfortunately he's thinking of the Sun sphere more like a vessel in his hand here on earth [instead of a free-floating ball of gas/plasma out in space] wherein the more water he pours into his vessel the more it weighs (whereas the whole entire Sun doesn't really weigh anything whatever at all [pouring "more" into it doesn't really make it "weigh" more]: the Sun's "weights" are all relativistically spread about/inside its space... much like "a pound of stuff" only weighs a pound on the surface of the earth... and if it is out "in space" it weighs nothing whatever at all--you know, much like the Sun itself).
This monkey, unlike the other poster, may be able to stand upright, but he's still a poor ole monkey, pure & simple...

Yes! --That-- happens to be my point:
The ongoing fusion reaction proves that in the Sun sphere Gravity could NOT be working as it OUGHT TO BE working:
There is NO MECHANISM in a gas/plasma ball (large enough for 1,300,000 Earths to fit in it) for the outer shell mass to transmit enough cumulative pressures to the core ... since gravity is actually declining the closer one gets to the core:
There are too many earth-masses around every earth-mass at, say, 1/4 of the way to the core pulling out towards the surface for it to "press" all its mass towards the core: In the end, once you start getting to 98/100th of the way to the core those earth- masses are pressing more against core- wards than core-wise [or, negative gravity --at the core itself there should be no gravity pressure at all]. Not being ONE SOLID BALL the earth-masses in the Sun have no way to add their gravitational pressure towards the core. SINCE they are obviously not falling towards the center like Newton apples but existing in place. Or:
Imagine not an earth-mass but one given atom "existing" inside the Sun sphere: ANYWHERE YOU PLACE IT it will always "feel" less and less "pull" towards the center the closer to the center you put it. THE SUM RESULT being:
The Sun is undergoing the pressure it's undergoing at its core NOT because of "gravitational pressures" but due to some other mechanism--And that mechanism... a velocity pressing towards center(s) ever since the beginning of time, is explained here:
> So, how thick is the shell or > gaseous outer wall of our sun?
If the universe operated as described by classical laws of gravity (e.g. via your mythical graviton) then probably the Sun would look like a big frozen planet (along with every other star). The "shell" might simply descend in density to a least dense center, that's all.
Fortunately the universe doesn't look inside the craniums of men to learn how it's permitted to work (or not):
Eventually men LEARN the Earth isn't flat. That the universe does not revolve around their itty bitty planet. And that the reason why gravitational anomalies suffuse the universe everywhere they look is NOT because "God likes lo create complex puzzles with wandering planets, and gravitational forces that don't act on the parts of a mass just on the whole of it" BUT because they have yet to fully grasp (understand) exactly how perfectly simple the workings of the universe really are.
You will have to shut your mind to the bunk more primitive monkeys than you have come up with throughout theis ascent from more primitive ages... to our howling day. But it can be done (by most monkeys, if not all).

You're not thinking straight:
I do not claim that the universe works in any way differently from how we know it works.
I do know that if gravity were producing "the effects of gravity," then the universe could NOT work the way we know it works (from the way gravity should work if it were to work according to its own laws).
ERGO my scenario of a "less dense core" for the Sun... if the universe worked according to the laws of gavity.
The Sun does not actually have a less dense core BECAUSE (see Newton's laws of motion) since the beginning of the universe everything in it has been accelerating towards ITS CENTER(s).
NOTE: Not towards "a" center because the sum total of its matter IS its center. THERE is no other matter in the universe than matter---I know this simplicity is hard for monkeys to grasp. And I have great sympathy for you, believe me. But eventually you will all understand it; just as you now understand that the math that proved Ptolemy's earh-centered notion didn't really prove anything except perhaps the over-cleverness of us monkeys.
In affect, the universe is acting like THE MOTHER OF ALL BLACK HOLES with every "bit of matter in it" being its "point of infinite density" (the very obviously misnamed "singularity").
EVERYTHING about us is telling us this is the case, but we are not yet prepared (as a monkey society) to see it (only I can see it--others may see it as well, or perhaps blurrily, sooner or later).
THAT is why denser (the more mass, given the same space) stuff "moves" toward center with "greater weight" (more impetus) than less massive matter (and why nearly mass- less particles like the photon seen to shoot about AT AN ALMOST INCREDIBLY CONSTANT SPEED regardless of where in the universe they are). And without knowing each other.
And why, the photon, after it slows down while passing through a denser medium suddenly re-speeds up after it hits a less dense medium, and WITHOUT having to fire any after-burners!
It's all explained from several different angles at:

You're thinking of a bowling ball there, friend:
[The Sun is not a bowling ball: If it were, we'd know where the pressure was coming from--But since the Sun is a ball of gas/plasma, it should perfectly "describes" the impression of gravity upon its matter ... exactly like the magnetic fields of a magnet's poles "describe" themselves on iron filings spread out on a sheet of paper under which you move said magnet. Do the experiment yourself. Remember: There is NO WAY for one of the Sun's "filings" (or: atomic particle) to "push" another anywhere: They should all travel towards where they are "pulled" by gravity. ERGO: If the Sun were indeed being "shaped" by gravity, there would be no/little pressure towards the core to carry out any fusion reaction. That is a physical fact which nothing in your philosophy can dispute. THERE IS fusion going on at the Sun's core, otherwise it'd be a big ole bowling ball.] Therefore, Tommy
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.

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 future: 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

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).

gravity pulls towards the centre of the sun. ergo the particles will go there and then pass through and head out the other side until turned around by gravity or mybe they hit something or interact electrically ...

nah it's part stupidity, part bullshit and part ignorance, it's just the ratio which is yet to be determined,

Rather than a cavity, the region is one of zero gravity!

The pressure assures that nucleii are closest to one anotther there. Fusion could be self-regulating... If it gets too hot, the core expands, moderation occurs and the fusion slows, etc. No thermostat required.

The vacuum concept is the one that does not occur, per se. In its place is the Zero gravity field, which allows for mixing with no gradients interfereing, an intersting cauldron.

My recollection og vraity theoryin bodies is as you say maximum at the durface and dcreases linearly into the core center
Very long winded. I never got to any core punch line.
Back to cores. We have a similar dilemma with the core of our earth. We feel pretty ceertai n that there is a lot of iron down there, but the distribution of that, and ligher, and havier substances is still undtetermined by our collective scientific society. Trouble is that if we (they) know very little about it, then Mim's the word, and nothing gets done.
Continuing on that thought experiment, It seems that gradients and stratification is for the mid and upper levels, but not for the lower levels toward the center. So all heavy atoms are down there, mixed in a soup. Radon gas is the only tracer from those environs besides heat and magma (the light stuff) This indicates residual decaay. Originally, I was of the opinion tha there is a farly large dose of heavier atoms that are still on their decay curve from original earth coalescence. This seems seems unhandy from the standpoint that because of the mesured age of the earth (hundreds of millions of years), it's incredible that any decay tails at all are still meaningful. But it is a long way from a nuclear exposion to just some melted iron. Has anyone made the calculation? The only other option is that there are daisy chain reactions in play; where "This" begets "That", and now "That" has a new lease on life. Hmmmmmmmmmmmm
