Zero Gravity at the Center of the Sun

[htert2020]

Basic laws of physics suggest that zero gravity must exist at the center of the sun. This is because gravitational force vectors would entirely cancel each other out at the center of any sphere of matter, excluding external gravitational forces, of course. For example, if a person was located at the center of the Earth, the gravitational force of an object in New York City would cancel out the gravitational force of an object in China of equivalent mass, as the two force vectors are in opposite directions. Extrapolating further, it can be said that for any piece of matter located anywhere within the sphere of Earth, a piece of matter of equivalent mass can be found at the opposite side of the Earth that cancels out the gravitational force vector caused by the first object, relative to the center of the Earth. So the person at the center of the Earth would feel no gravitational force from any piece of mass from anywhere on the planet. The same principle should apply to the sun, as the sun is supposedly, according to conventional theory, a sphere of gas. With a net gravitational force of zero at the center of the sun, there cannot possibly be thermonuclear fusion at the center. Nor can matter located near the outer edges of the sphere apply any pressure on the center, because the mechanical stress due to gravity would exist mostly on the outer edges of the sphere and such stress would steadily decrease to zero as one moves toward the center of the sphere. For example, if you pick any piece of matter located reasonably close to the center of the sphere, perhaps at 1/8 radius away from the center, that piece of matter cannot possibly "crush" the center with any significant strength due to gravity. That piece of matter would be pulled toward the center by matter located the other side of the sphere, yes, but it would also be pulled by the part of the sphere in the opposite direction, creating only a small net force toward the center.

How would conventional nuclear fusion theory address this concern? Has it already been addressed? I certainly can't find any error in my thinking above, unless someone can point it out for me. For now, I see it as something that can totally discredit conventional nuclear fusion theory, which impacts our understanding of all stars in the universe, including the supposed "black holes".

Apologies. I was a little unclear when I said, "So the person at the center of the Earth would feel no gravitational force from any piece of mass from anywhere on the planet." What I really meant to say was that the person at the center would experience no net gravitational force -- no net acceleration in any direction. This is what I mean by zero gravity. The person at the center of the Earth would be floating in space if a vacuum existed there.

I think the solution for mainstream science is while there is no net gravitational force at the center, all particles around the center are being pulled inward by the gravitational force they feel which causes a large pressure at the center, not gravity.

[earls]

I don't think many would disagree with you on the premise of almost zero gravity at the center of celestial bodies.

I offer two theories:

1. The crust is collapsing back towards the center because of the attraction from the other side. The collapsing crust compresses the innards of the body (attempting to expand from heat generated by the pressure). So it's a constant tug-of-war between the innards trying to get out and the outer shell trying to get in.

2. I'm much more inclined to accept the EU version (hence my presence here : ) of an electrical current creating an electromagnetic "z-pinch" in the center, thereby dismissing the need for gravitational compression altogether.

[junglelord]

I agree with earl 100%.
Total command of the better paradigm.
Simple and pricise.
The center is indeed a Z Pinch.
There is transmutation going on quite possibly with neutrinos
into electrons according to Meyl to further that paradigm.
But it is a paradigm.
The EU.

Will do. You are confusing lack of gravity with lack of pressure. Just because there's no gravity at the centre of the sun doesn't mean that there is no pressure.

To illustrate, let's assume you have three blocks of wood and four rubber bands that are the same length.
The blocks represent layers of the sun at different depths, the rubber bands will represent gravity.
You have the centre. Your rubber band is lying on the desk, all limp, no attraction.
You put a block on the desk and sling a second rubber band around it, so that it pulls the block down on the desk. It's not very tense (representing weak gravity), so it doesn't pull much, but it's already exerting some pressure.
Now, you put the second block on the first, and sling the third rubber band around it so it presses down on the block below it. The pressure exerted on the block below is higher because the rubber band is more tense (representing higher gravity).
You then put the third block on top of the second block, and sling the last rubber band around it so that the third block presses down on the second. That third rubber band is very tense, representing full gravity, and exerts a lot of pressure on the second block.

Now comes the important part: How much pressure is exerted on the desk, where the tension (gravity) is 0?
Simple. The pressure exerted by the first block being pushed down, PLUS the higher pressure of the second block pushing the first block down, PLUS the pressure of the third block pushing the second block down.

So we have a lot of pressure despite the gravity being zero. I hope that was clear enough, it was the best explanation I could come up with on short notice.

[faceoff]

Pressure is caused by any kind of force, so if the gravity is 0, there could not be pressure caused by force of gravity. Sorry, but I failed to see where is the 0 point in the example with the wooden blocs.
The fact is that a new theory of electro-magnetic universe is much more probable. It might open completely new way of understanding what is really connect universe all together. The gravity theory failed, and never will be able to explain it, simply because they will never find an extra matter that will fulfill gaps in calculations based upon this theory.
Than again some time ago, I tried to deal with phenomena of magnetism, and to my surprise everything I came up to, pointed that electro-magnetic fields are responsible for much more than previously thought.
Due to lack of time I didn't dealt with the problem for some time, but all the researches in a mean time confirmed mine findings.
It is quite close to the approach you applied to a problem of 0 gravity. Than again theory of gravity never will be proven 'cause it is not possible to create a system required for experiment which would prove it...
Think over the problem of vacuums, you might find it illuminating... absence is a powerful force!!!

The 0 point is on the desk.
You are making the mistake of thinking that the pressure has to be generated locally. The pressure is generated on the surface, where all of the mass of the sun pulls down. Think of it as a giant weight pushing down. No gravity at the centre only means that there's no attraction at the centre, it doesn't mean that already existing pressure from above goes away.

The fact is that a new theory of electro-magnetic universe is much more probable. It might open completely new way of understanding what is really connect universe all together. The gravity theory failed, and never will be able to explain it, simply because they will never find an extra matter that will fulfill gaps in calculations based upon this theory.

Irrelevant to the point we are discussing, as the pressure is easily explained with gravity alone.

Except we aren't dealing with absence here. The gravity exists at the surface and below, weakening as you get closer to the centre. The inward-pointed force (weight) of the upper layers presses down on the layers below. It propagates down through the matter.

[faceoff]

Well, JUNGLELORD, as well as I already wrote ( sorry for my english,it's not mine native language), absence is a powerful "force".
I haven't sow your comment when I reply in my previous letter. Remarkable notification about 3,6 and 9 done by NT, I'm quite surprised you quoted it.
I'm just wondering if you know what he referred to, mentioning those numbers. Anyway those numbers and relations among them, and reflection of those relations to different types of fields were primary into mine observations of phenomena of magnetism.
THEREFOR I would most kindly ask for explanation over your statement -Casting Out the Nines from PHI into Indigs reveals the Cosmic Harmonic Code.- I'm afraid I'm not familiar with acronym such as PHI and having a problem with understanding phrase " PHI into Indigs". Hopefully waiting for yours clarification...

faceoff just took the red pill.

An alternative way to think of it is, going back to block and rubber bands..., take three blocks sandwich style with a rubber band around all three. The rubber band represents gravity pressing inward on the outer blocks (ignore the force of the rubber band on the side, just the faces of the two outer blocks). The force is only acting on the outer two blocks, the inner one doesn't have a force acting on it but the force on the two outer blocks still presses on the inner block (put your finger in between to test )

I'm not saying your whole idea isn't valid, given a solid spherical shell and a central inward force it seems like the shell would hold up under the force and the inside of the shell could still be hollow...

[faceoff]

So, lets check some basic math: if there is a triangle a,b,c where a=3,b=4,c=5 angle opposite to (c) will be 90 degrees.
a^2+b^2=c^2, well not quite. Lets try something else, 3x3 + 4x4 = 5x5 if we replace 2x2 + 3x4 = 4x4, 1x1 + 2x4 = 3x3,
so it is a^2+bx4=c^2 (-3)x(-3) + (-2)x4 = (-1)x(-1), (-7)x(-7) + (-6)x4 = (-5)x(-5), from - indefinite,
to + indefinite.

Check it if you please. What this got to do with 0 gravity at the center of the Sun?
Nothing, probably. Still, you forgot the moment of inertia which allows projection of pressure into center of a sphere, any. Sun, planets, etc...
I've told you, try to apply that way of thinking on the center of the galaxy, I believe you will find much greater things...

JL. would it be too much to ask to direct Faceoff to the proper thread?

[moses]

Consider that the Earth is hollow. And consider the evidence that gravity is not
what is expected at the bottom of a deep mine. Now the expected gravity would
be the sum of all the gravity formed from mass below the measuring instrument
minus that from the mass above this instrument. Now when the Earth is hollow
there is a large amount of mass missing in the middle of the Earth, so that the
usual calculation of gravity would be in error. In fact, this means that a calculation
of what gravity would be with a certain depth of matter (crust), could be compared
with the actual measurement, and thus give an estimate of the thickness of the
surface of the Earth. If this agreed with the depth that seismic measurements
can be interpreted to give - then that is real evidence of a hollow Earth.

Thanks for all the replies. Your explanations are well appeciated.

As it turned out, the solution to the problem came in my REM sleep earlier today before I checked these replies on this blog. Yes, I agree, I didn't consider the importance of what pressure can do to the center of the sphere. At the center of the sphere, there would be zero gravity -- that is, an object at the center would experience a net gravitational force of zero and would feel weightless. But imagining that the sphere is actually made up entirely of billions of small basketballs, a basketball located at the surface would apply a huge downward force on the basketball immediately beneath it, causing it to want to accelerate toward the center of the sphere. In addition, that second basketball would experience another downward force due to its own gravitational attraction toward the center. This second downward force is similar to the first downward force, but just a tiny bit smaller, since it's located closer to the center of the sphere. The second basketball would then apply a cumulative force to a third basketball immediately beneath it, and so on, until the total cumulative force (due to pressure) on the center of the sphere is huge.

One manifestation of this principle is that water pressure is small near the surface of an ocean; the pressure is huge when you get to the bottom of the ocean. If a large cosmic sphere consists entirely of water, then water pressure should be huge at the center of the sphere.

The reason why I brought up this whole subject is that I thought it might have been an obvious hole in the conventional nuclear fusion theory of mainstream. Oh well.
