Fotini Markopoulou-Kalamara: "Quantum Gravity", FQXi Azores Conference 2009

CERN might as well be watching supercooled hydrogen giving gravity the liquid digit. Would supercooled antihydrogen do the same. Does this mean gravity is entropic? Are protons entropic because they don't decay in the woods? I patiently await the answers to all these burning questions.

[CACBCCCU]

National Geographic is now on the bandwagon with "hot perkin' coffee gravity dipoles in a cold vacuum flask" antimatter physics. Are these people aware that even the Casimir force practically disappears when it gets cold enough. One hopes not.

[CACBCCCU]

It'd be simple in many ways, I suppose, if all antimatter falls up, but if it's assumed all positive charge is based on an antimatter part of the charged particle, then the unbound positron would be the only particle capable of falling up. I've tried to address the whole "interstellar emptiness is chock-full-o'-mass-dipoles" theory before, how hot surface physics ever reached so far out into the emptiness of space I can only guess. Casimir backscatter? Might as well call them Higgs dipoles.

[CACBCCCU]

Looks like black holes are losing out to fuzzballs or whatever they're calling them these days. With a spinning fuzzball there is the possiblility of huge magnetic fields, considering electron/proton mass difference implies the protons end up concentrating along the fuzzball's spin equator. I've dissected entropic gravity under the video "Gravity Doesn't Exist." Something like a Hoag's Object ring can't be cast thermodynamically, magnetically, or with GR, however, as they all lack gravitons.

[CACBCCCU]

Not sure how an open-space virtual dipole dielectric effect fits SR, seems the virtual pair is virtually static. For masses in the same frame a question arises what frame is the controlling virtual dipole medium in. Seems there could be induction/relaxation time and the effect would be frame-velocity-dependent. There seems no issue with SR frames when applying a corner-reflected exchange tendency, but it's still complex, as quantum exchanges nonetheless can bunch up, much like flux lines can do.

[CACBCCCU]

The gravitational dipole-space concept seems to cover a dark-matter aspect of gravity that I've often equated to a surface-tension-like effect or an influx-redirected corner-reflector type of action in gravitational flux exchanges, which conceivably in my mind might relate well to a tight borromean ring model of quark position potentials, the upshot being that low energy systems of masses tend to largely hold onto their gravitostatic quanta. I've covered that elsewhere maybe too much already.

[CACBCCCU]

I notice a physicist from CERN is saying the Tully-Fisher relation derives from gravitational repulsion between matter and antimatter. There's a bias to edge-on galaxies in velocity width. Anyway, the idea that gravitational dipoles are generated by virtual pairs has a lot of merit at high energies, but in wide-open spaces it seems more a possible related infinitesimal effect rather than a cause of dark-matterish behavior. I think it's in the right direction, but it needs a push from gravitons.

[CACBCCCU]

For NGC 4710 compared to other galaxies, being seen almost on the spin plane seems to amplify the diffuse glowing halo effect. I get the impression the arrow-shaped tip on the right end could be a product of lensing and rotation of the galaxy. It's as if gravity gathers some of the axially-aimed light and re-distributes it along the spin plane, where the galactic spin rate adds a certain amount of light imbalance between the left and right edges..

[CACBCCCU]

Seems one issue is that I'm suggesting gravitational flat-space crossover potential gradients where others believe steep gravitational negative-potential gradients would suffice. Perhaps it is bias on my part. Complicating things is that the crossover seems like a good locus to associate with a glowing hot vacuum representing annihilation events if one presumes, e.g., positrons have negative mass, an assumption that seems justified by the notion that it perfectly mimics a time-reversed electron.

[CACBCCCU]

NGC 4710 is an example showing the previously-mentioned quadrupolar "X" pattern crossing the core. It seems to be somewhat like a gravitational lensing "caustic."

[CACBCCCU]

Beyond what I wrote earlier, galaxies also often seem to show a quadrupolar diffuse lensing effect centered on the core, sometimes making a core appear boxy when seen edge-on, maybe making a central "X" pattern or part of a "/" line. There is a certain diffuse redirected-light brightness to it with a very saddle-like quadrupolar aspect. Not sure if GR covers the existence of the effect as core-(mass)-centered, as it does not allow off-galactic-spin-plane regions with negative-mass character.

[CACBCCCU]

Thanks for the video. I wish someone knew how to post-process the audio with a time-domain equalizer, it's on the boomy side. Maybe if I listen to it several times...

[CACBCCCU]

A gradient reflectivity of absolute negative gravity lensing open space is something I think is shown fairly often in galactic structure, like a core-enveloping graduated brightness region that cannot be resolved to any stellar structure.

[CACBCCCU]

Negative lensing space in GR is always like a hyperbolic saddle or a radial set of saddles, depending on the number of space-defining objects one's massless viewpoint is centered within. If there is such a thing as negative mass there would be a new type of negative lensing space without saddle-points. Such a space would transform distant convergent light paths, deflecting them divergently. I suppose the outside effect seems much like seeing a concentric series of partially-reflecting surfaces.

[CACBCCCU]

Seems like some issues with the quantization of GR could be resolved in the same way SR was able to simply quantize EM if GR was regeneralized to cover opposite gravitational charges. With EM the wave-medium gets replaced by media-less photons that can express magnetism's steady-state attraction or repulsion, forming flux-lines. If these "virtual" (i.e. invisible) photons of steady-state magnetism have an h-nu frequency it's apparently practically indistinguishable from zero-frequency.

[CACBCCCU]

Seems time always goes in the direction of gravity being seen as an attractive force, and the only way there could be any confusion about that is if there exists negative mass repelling positive mass, i.e. in gravity, charge opposites repel and likes attract, in which case gravity seems in one sense like an ultra-low-energy cutoff of EM but it operates orthogonally. Though complex numbers cover the EM field, quaternions seem necessary to cover both types of charge-relation in EM and G together.
