[Vo]:Dark matter may be an illusion caused by the quantum vacuum
http://www.physorg.com/news/2011-08-dark-illusion-quantum-vacuum.html (PhysOrg.com) -- One of the biggest unsolved problems in astrophysics is that galaxies and galaxy clusters rotate faster than expected, given the amount of existing baryonic (normal) matter. The fast orbits require a larger central mass than the nearby stars, dust, and other baryonic objects can provide, leading scientists to propose that every galaxy resides in a halo of (as yet undetectable) dark matter made of non-baryonic particles. As one of many scientists who have become somewhat skeptical of dark matter, CERN physicist Dragan Slavkov Hajdukovic has proposed that the illusion of dark matter may be caused by the gravitational polarization of the quantum vacuum. “The key message of my paper is that dark matter may not exist and that phenomena attributed to dark matter may be explained by the gravitational polarization of the quantum vacuum,” Hajdukovic told PhysOrg.com. “The future experiments and observations will reveal if my results are only (surprising) numerical coincidences or an embryo of a new scientific revolution.” Like his previous study featured on PhysOrg http://www.physorg.com/news/2011-07-big-quick-conversion-antimatter.html about a cyclic universe successively dominated by matter and antimatter, Hajdukovic’s paper on a dark matter alternative is also an attempt to understand cosmological phenomena without assuming the existence of unknown forms of matter and energy, or of unknown mechanisms for inflation and matter-antimatter asymmetry. In the case of the fast rotational curves of galaxies, he explains that there are currently two schools of understanding the phenomenon. “The first school invokes the existence of dark matter, while the second school invokes modification of our law of gravity,” he said. “I suggest a third way, without introducing dark matter and without modification of the law of gravity.” His ideas (like those in the previous paper) rest on the key hypothesis that matter and antimatter are gravitationally repulsive, which is due to the fact that particles and antiparticles have gravitational charge of opposite sign. (Though like matter, antimatter is gravitationally attractive with itself.) Currently, it is not known whether matter and antimatter are gravitationally repulsive, although a few experiments (most notably, the AEGIS experiment at CERN) are testing related concepts. “Concerning gravity, mainstream physics assumes that there is only one gravitational charge (identified with the inertial mass) while I have assumed that, as in the case of electromagnetic interactions, there are two gravitational charges: positive gravitational charge for matter and negative gravitational charge for antimatter,” Hajdukovic explained. end

This is the same hypothesis that the Brightsen model of the nucleus makes and proposes that there is dark matter bound in some nuclei.

-Original Message- From: Terry Blanton I suggest a third way, without introducing dark matter and without modification of the law of gravity ... the key hypothesis is that matter and antimatter are gravitationally repulsive, and there are two gravitational charges: positive gravitational charge for matter and negative gravitational charge for antimatter, - Hajdukovic Hmm... when you tie this in with Don Hotson and the Dirac epo field... with that field being identified more or less AS the quantum vacuum itself - then the conclusion is that positronium, either virtual or real, would demonstrates this hypothesis in a surprising way. The positron, being antimatter repels the electron gravitationally and at the same time attracts it electrostatically, so that there is a perfect balance! ... and this is the way the epo is held together. Since epos define zero point, then everything else builds on this dynamic structure (in the background). Since the mass of either component is identical in an absolute way (either a positive or negative) but neither is dominant, then the result is essentially a dense neutral background in which we are immersed. The background itself - although hidden - represents as much as 90% of all mass, and it is in a dynamic tension. This is Dirac's so-called sea of negative energy and in effect, Hajdukovic is simply redefining dark matter - and not really supplying a valid alternative. It still ALL goes back to epos. The opportunity, if there is one, which presents itself with this insight and more precise understanding of ZPE, is not obvious... except for this one point: Perhaps the easiest way to look for a way to harness ZPE is to look for anything which seems to change gravity ... which can include not only an anti-gravity effect but also the opposite - a super-gravity effect (putative weight gain). This may or may not be related to a kind of supergravity which is the basis of superstring theory. http://en.wikipedia.org/wiki/Supergravity However, there does seem to be one interesting cross-connection of all of this to experimental results. This will be the subject of another posting, as this one is getting a bit unwieldy. Hint: IRH (inverse Rydberg hydrogen) or fractional hydrogen (f/H) aka ... the Mills' hydrino, pycno or spillover hydrogen - all of these terms are descriptive of what is essentially a heavier form of hydrogen. Instead of a 'reduced orbital' we could be looking at an increased coupling to gravitons ... :) Jones

Terry sez: The positron, being antimatter repels the electron gravitationally and at the same time attracts it electrostatically, so that there is a perfect balance! Hmmm, what are the odds of that? Following up: Also, considering the fact that electrostatic forces are probably a on an order of a gazillion times stronger than equivalent gravitational forces. How is there a perfect balance? Strikes me more like a big asymmetry. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks

The dense neutral background must have effectively no inertia, otherwise stable orbits would soon collapse.

Re: [Vo]:Dark matter may be an illusion caused by the quantum vacuum
I know little about cosmology, but is it not the case that: If dark matter exists the universe is more likely to end in a cosmic crunch, relatively soon. If it does not exist the universe will end with heat death much farther into the future. Just curious about this . . . Freeman Dyson wrote an essay saying that with a large enough reserve of energy civilization might last indefinitely or perhaps he said infinitely long in a heat-death scenario. I do not understand what he had in mind. You have to run out eventually. - Jed

Freeman Dyson wrote an essay saying that with a large enough reserve of energy civilization might last indefinitely or perhaps he said infinitely long in a heat-death scenario. I do not understand what he had in mind. You have to run out eventually. Regarding some of these newly discovered forces like Dark Matter Energy. I think it gets even messier than that. First there are the four known forces we all love, listed here in order of diminishing strength: 1. Strong (nuclear forces) 2. Weak (beta-decay) 3. Electromagnetic forces 4. Gravity But in recent times we must now tack on two additional hypothetical forces that are presumably based on recent measurements painstakingly correlated from powerful telescopes like the Hubble. These two new forces are listed below in order of diminishing strength. 5. Dark Matter: a hypothetical force, that is attractive by nature in the gravitational sense. This force is supposed to help explain why galaxies spin faster than they should - presumably because there is a lot of unseen, undetectable dark matter milling about producing a lot more gravity than what is seen. - THE BIG CRUNCH. This is where some might wish to evoke a marvelous whimsical essay written by Carl Sagan. The essay is titled The Dragon in my Garage. Jed, since you are an atheist at heart, I think you might enjoy the following essay. It is from another kindred soul. See: http://www.godlessgeeks.com/LINKS/Dragon.htm And finally... 6 Dark Energy. We are told there also exists another hypothetical force called Dark Energy, which seems to be repulsive in the gravitational sense. Dark Energy is supposed to explain why most galaxies are not only flying apart from each other, but that the measured acceleration is increasing. - The BIG CHILL The really weird thing about forces 5 6 is the fact that both forces seems to depend (or manifest) depending on the distance between the physical material itself. In other words corresponding matter within a galaxy is close enough in distance to each other such that the dark matter attractive force is in full effect. However, corresponding matter as measured between the vast distances between galaxies seems to be far enough apart that the repulsive Dark Energy force now comes into effect. Do you understand now, Jed? If so, maybe you can x'plain it to me cuz I still don't get it. I lost track of that dragon long ago.

RE: [Vo]:Dark matter may be an illusion caused by the quantum vacuum
Steven, a logical error could be in assuming gravity and antigravity are perfectly symmetric in an inverse way, or that antigravity scales in a similar way as gravity all the way down. This may or may not be true, since the big (HUGE) hurdle to overcome first is to document that antimatter is anti-gravitational. There are few experts in this field and no definitive experiments. There are various theories beyond the Standard Model which include attempts to resolve the hierarchy problem, include deviations at very short distances - but no real experiment goes below micron level for gravity AFAIK... hard to build scales that small. Obviously, no evidence speaks to antigravity at close range either. There are a few superficial reasons to suggest why gravity should never be able to be unified with the strong force below picometer, but nothing I have seen is very convincing. You will find vocal advocates of the extreme unification hypothesis, but they are even less convincing (Lazar etc). Bottom line - it is an open issue, and at picometers distances there is nothing indisputable so far - which prohibits a perfect balance of antigravity and electrostatic attraction (which has the effect of stabilizing the epo field into a dense, neutral, static lattice in another dimension). This picture does have a kind of elegance, if it turns out to be accurate. In fact, since antigravity appears repulsive for normal matter - then we might expect antimatter to come with its own repulsive version of the strong force: at least it would be repulsive wrt normal matter. -Original Message- From: OrionWorks - considering the fact that electrostatic forces are probably a on an order of a gazillion times stronger than equivalent gravitational forces.
