writes Sun's massive magnetic field that reaches well beyond the orbit of Pluto! The Sun has a paltry magnetic field, are you thinking of the Solar Wind? If the fields of Earth and Jupiter were both approximately represented by bar magnets at the planet's centre, then Jupiter's magnet would be about 20,000 times stronger. Its strength is irrelevant, because the Sun's field is defined by the heliopause, which is somewhere beyond the orbit of Pluto - no probe has yet got that far. I think Bill's right on this one. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

There are certainly other mechanisms that generate magnetism, such as the geo-dynamo within the Earth. An on the sun, those great looping prominences are clearly spinning 'flux tubes' generated deep within the sun. With the sun so robust magnetically, it's not surprizing its field should reach 'way out thar, i would think. Anything that'll impart a spin component to a spatial flow will produce magnetism, not just the strong force within atomic nuclei. oc nightbat Hello oc and Painius, thought you might like this link about reference to renormalization group flow, spin, quantum class magnetism, and universality classes. See:http://en.wikipedia.org/wiki/Renormalization_group Hope this helps in your discussion. the nightbat That stuff is *way* over my head, nightbat. Are you able to sort of translate it? I have no idea what it all means. And Bill, in my imagination, i do not see the strong force as the "cause" of magnetism. While other things may cause magnetism, i see the strong nuclear force as the "source" of magnetic force. The difference is like the source of a river, which is quite different from what causes the river to flow. And i have a problem with gravity also being sourced by the strong force in addition to magnetism... You said... Yet what is magnetism if not the spatial inflow into the _poles_ of the proton into the seat of the strong nuclear force within? Seems sorta like a no brainer. Magnetism's 'sign', i.e., its 'N' and 'S' polarity, is determined by spin direction of the inflow. and then you went on to say... 'Local' gravity, the kind we're familiar with, is the collective 'influence at a distance' of the the strong force, minus the spin component of magnetism. Thus gravity is monopolar. I cannot see this because i do not understand how both gravity and magnetism can be sourced from the same nuclear force without there being some noticeable effect. Magnetism appears to be unaffected by gravity and vice versa. You are saying that when there is no spin component, you have local gravity. And when a spin component is introduced, then you have *both* gravity and magnetism sourced by the same nuclear force... the strong force. Then why don't they affect each other dramatically on a macro-level? This is one reason why i can more easily imagine gravity as being sourced by the Weak Nuclear Force. happy days and... starry starry nights! -- Delight in yourself... for you are the stuff of stars!

... IIRC, some while back you questioned why some materials are magnetic and others not. Under the spinning flow model, apparently the atomic structure of most matter is 'transparent' to the spin component, rendering it nonmagnetic, while magnetic material is 'opaque' to the spin component. Zinni'll have a field day with that oneg if he hasn't already used his 'Plonker'. oc Not quite sure what you mean by "transparent" and "opaque" here, Bill, but i've always felt that some atoms are just more easily spun than others. And some are very resistant to any spin and "lining up" that would manifest itself as magnetism on the larger scale. As for Zinni, John has never particularly struck me as much of a wussie. He'll argue the mainstream until he's blue in the face, and i respect his healthy skepticism. But he doesn't strike me as being so afraid of a poster as to plonk him or her. The only thing people like John are afraid of is missing something. They may ignor a poster, or at the very least ignor responding to him, but plonk him? probably not. -- Sittin' on the porch stair holdin' your love, A wonderin' how lucky you are, A huggin' anda kissin' anda lookin' up above-- There went a Shootin' Star!

I did try to find out.
I knew Jupiter has a massive magnetic field and dangerous radiation fields many times more lethal than our own Van Allen belts. But the Internet only provided conflicting values. Most of the suns energy is in other areas. The strength of Jupiter's radio output was a complete surprise when it was first discovered. Because an object can get closer to the origin (inverse square law and all) I considered Jupiter's output stronger to the suns in so far as where one could be in relation to the centre of it all. Jupiter's radiation can kill an errant astronaut within a few minutes of exposure. Regards Robert "Painius" wrote in message ... "Robert McCurdy" wrote... in message ... Painius wrote...

From Painius:
..i have a problem with gravity also being sourced by the strong force in addition to magnetism... Well Paine, once you can comfortably visualize both gravity and magnetism as being flows of the spatial medium into mass, what is the ultimate destination of the flow? Is it not into the seat of what is called the 'strong force'? The term "force" as used here is a psuedoism in the same sense as 'centrifugal force'. The only true force involved is what Wolter called the 'supra-cosmic overpressure'(SCO) driving the flow. The SCO is the true source, driving into the flow sump, or drain, the seat of the 'strong force'. Thus gravity and magnetism are not "attractions" but pressure-driven flows. Odysseus mentioned electron spin as 'causing magnetism'. While electron spin aligns equatorially to the proton's polar axis, it does not "source" or "cause" magnetism, as in the old adage "correlation does not prove causation". Then why don't they (gravity and magnetism) affect each other dramatically on a macro-level? What about a maglev train? This is one reason why i can more easily imagine gravity as being sourced by the Weak Nuclear Force. Well, since the weak force operates in the subnuclear domain and does not participate in spatial flows 'out here', perhaps it could be regarded as a subset of the "strong force". But then, if space is pure void and 'nothing', none of the above applies. BTW, i wasn't insinuating Zinni is a wuss. He had complained of being bored by reading this stuff, so in suggesting he use his plonker, i was trying to spare him the discomfort of being bored. oc |

Well Paine, once you can comfortably visualize both gravity and magnetism as being flows of the spatial medium into mass, what is the ultimate destination of the flow? Is it not into the seat of what is called the 'strong force'? Yes, this is what i'm challenging. I say that gravity and magnetism are isolated enough in the macro level to be sourced separately. The term "force" as used here is a psuedoism in the same sense as 'centrifugal force'. The only true force involved is what Wolter called the 'supra-cosmic overpressure'(SCO) driving the flow. The SCO is the true source, driving into the flow sump, or drain, the seat of the 'strong force'. Thus gravity and magnetism are not "attractions" but pressure-driven flows. Truthfully, this SCO goes well beyond my ken. Even if Wolter is correct, gravity and magnetism would interact more, would, say, behave in the same manner as electricity and magnetism, if they were both sourced by the strong nuclear effect. Odysseus mentioned electron spin as 'causing magnetism'. While electron spin aligns equatorially to the proton's polar axis, it does not "source" or "cause" magnetism, as in the old adage "correlation does not prove causation". And yet there is a strong enough correlation to give a lot of weight to what Odysseus says. I agree that electron spin is a factor in magnetism. And he mentions "ferromagnetism." This indicates that there is more than one form of magnetism, and that there may be several ways that electron/nucleus spins may affect the macro-level force. It may even be possible that, say, diamagnetism is sourced by the WNF. Then why don't they (gravity and magnetism) affect each other dramatically on a macro-level? What about a maglev train? Naahhht! This is little more amazing than an airplane, Bill. The Japanese use superconductivity which adds to the fascination, and the US is cautiously looking into room-temp superconductive models, but in the end, it's aerodynamics helped by massive magnetic attractions and repulsions that provide the antigravity effect. It's the same thing with the Dutch frogs, and probably so even with the controversial "anti-gravity machine" of Dr. Eugene Podkletnov. Bottom line is that none of this indicates an interaction between magnetism and gravity. At least not the kind we see between magnetism and electricity, where you "can't have one without the other." Gravity and magnetism are isolated and appear to be sourced by isolated forces or "effects." This is one reason why i can more easily imagine gravity as being sourced by the Weak Nuclear Force. Well, since the weak force operates in the subnuclear domain and does not participate in spatial flows 'out here', perhaps it could be regarded as a subset of the "strong force". Good possibility of this, yes, however, we apparently disagree in the same manner as you disagree with the mainstream... Mainstream: Neither the SNF nor the WNF have any effect beyond the boundaries of the nucleus. Bill and Wolter: The SNF *does* have an effect beyond the nucleus that manifests itself in the macro realm as magnetism *and* as gravity. The WNF has *no* effect beyond the nucleus. Paine: Both the SNF *and* the WNF have an effect beyond the confines of the nucleus. The SNF manifests itself as magnetism, and the WNF, additively with the WNF's of other atoms, "reaches out" and appears to us as... gravity. But then, if space is pure void and 'nothing', none of the above applies. BTW, i wasn't insinuating Zinni is a wuss. He had complained of being bored by reading this stuff, so in suggesting he use his plonker, i was trying to spare him the discomfort of being bored. oc He was just tryin' to **** you off, you ol' coot!

However, i respect your skepticism and agree that electron spin plays a major role in magnetism. Since science is still only scratching the surface of quantum magnetism, gravity, etc., hopefully you will accept that, at this point, almost anything is still possible? Science presently teaches that there are four fundamental or universal "forces" in nature. In order of strongest to weakest they are... Strong Nuclear Force = 1 Electromagnetism = 0.001 Weak Nuclear Force = 0.0000000000000001 Gravity = 0.00000000000000000000000000000000000000001 ....and the figures represent *calculated* relative strengths. ("calculated" as opposed to "measured") What if Bill is right? Suppose there is really only *one* universal force, and that the above "forces" are only manifestations or "effects" of this one universal force? This might explain why our greatest minds have yet to unify these so-called forces? Maybe the one universal force is something we haven't yet observed?
