YOu didn't read my comment and missed the meaning entirely. Read this:

Either gawd doesn't exist, or if creation is a deliberate conscious effort, then it is the creation of a sadistic evil beast.

With an infinite choice of ideas, why would a creator choose the food chain, predation, devouring of prey, and endless torture as a good ideal.

Only because it causes the most drama and entertainment in the worst form of sadistic voyeurism. If a gawd exists, it is pure evil and must be destroyed.

Hello baptist.

Please,if you comment on a SCIENCE video,dont go off topic with your debate about how all mighty the gods are.THIS IS GODDAMN SCIENCE! No need to talk about how science is "unnessary" if you believe in god.Science is all about investigating,testing,analyzin­g,hypothesize,and report.Now leave with your non-science bullcrap.

Why do we all have to complain about religion every time we touch something controversial? Can't we just leave each other alone?

A Hubble picture of a gravity-lensed pair of accretion-disk images is in the news. I noticed one image of the quasar seems exactly twice as far from the center of the lensing-galaxy as the other. Seems to fit with the 2nd and 3rd minima of a galaxy-scaled steady-state quantum gravity wave like the one I suppose forms Hoag's ring. On the other hand, maybe there are just a lot of misleading coincidences/illusions way out there I'm prone to falling for.

[CACBCCCU]

Main thing I left out about galactic bars with different sizes, which I think is quite relevant to dark matter by the way, is that it seems to me that galactic systems can gradually lose their core-based gravitational coherence over time, doing so more quickly when not in an isolated region. Rather than having an abrupt effect on the length of a galactic bar, it seems loss of core gravitational coherence can gradually reduce the size of the barred region as the outer ring collapses.

[CACBCCCU]

Also back in the news is observation of a miniscule graduation in the fine structure constant in different galaxies. Don't know what to think of it, except the same metals are apparently still there and recognizable regardless, so maybe the same organic chemistry is still there and it seems to suggest a miniscule variation in free-space electric permittivity. Anyway I suppose it doesn't change the apparent length of a galactic bar significantly.

[CACBCCCU]

The gist of the paper "Galaxy Zoo: bar lengths in local disc galaxies" seems to be that bars have different lengths. Relating a stellar type to a particular broad region showing spectra associated with that type, though resolution to a single stellar object is impossible within that region, is apparently SOP, and I don't suppose lensing models are infallible, so questions remain. I don't always suppose proton E/G force ratio is the same for all galaxy cores, either, but it'd be nice if true.

[CACBCCCU]

Just saw an article about a new paper "Galaxy Zoo: bar lengths in local disc galaxies" and I'm not sure what to make of it at the moment. The article does not explain whether the lengths are taken as absolutes or as relative to the size of the galaxy, the paper isn't free. Maybe a relevant thought to mention here is that lensing effects can be confusing, they can change the shape and size of stellar groups and probably don't always get recognized for what they are.

[CACBCCCU]

NGC 5701 is one of my favorites, though it seems to be breaking up. I wouldn't be surprised if the outer ring was rotating in the opposite direction of the bar, which seems possible if graviton spins are biased to one direction instead of having the unbiased spins apparently shown with Hoag's Object.

So, anyway, dark matter misses another Nobel, and it's no deep mystery why that's fine with me.

[CACBCCCU]

Galaxy Zoo Forum has a picture thread on Hoag type galaxies. I suppose it's possible to see successive phases of graviton rotation at successive distances from the galactic core. Ring galaxies seen from an angle typically show what looks to me like a sideways gravity-lensed inner opalescent spherical effect where the first sideways phase of core gravitons peaks (~15kly radius) and the opalescent region is brightly-bound inside a dark region of reverse phase core gravitons (~30kly radius).

dude... ow my head

[CACBCCCU]

The "g-wave" quantum gravity wave-cycle I'm going on about here eventually led to reding Dirac's large numbers hypothesis in protonic version, matching the 10^36 difference between proton size and Hoag's galactic ring size, and from there to anti-matter concepts. The cycle is not one oscillating over time at any point in space, but an impartable potential oscillating in direction as quanta propagate, thus surrounding a fixed source with fixed concentric positive and negative gravity regions.

[CACBCCCU]

Believing I've seen, most evidently via Hoag's Object, the effect that a sufficient number of coherent (co-sourced) gravitons can provide, in the form of what seems to me to be a highly-stable fixed-size core+ring galactic configuration, I developed a quantum gravity based on a spin 1 graviton, plus a way by which gravitons tend to pair-off for a spin 2 effect. In the model an ultraslow spin 1 sinusoidal field applies to all gravitons, while matter matches and directs influxes toward outfluxes.

[CACBCCCU]

I tend to think of spirals as pre-rings or destabilized rings that may or may not be able to regain a ring configuration. So, in contrast to Hoag's object where a galactic-plane radial section favoring antimatter via a ~60Kly core-based steady-state g-flux cycle is dark enough to imply there's not any pure antimatter associated, it not that there's appreciable antimatter in the MW's spin-plane to eliminate a dark ring, it's that a bright ring structure doesn't have an opportunity for stability.

[CACBCCCU]

I tend to think of a photon as an object that always carries a particular number of largely co-moving gravitons that are practically always half of a set of path-sharing opposite-direction graviton twins, but a photon is not picky about replacing some gravitons as the photon prefers to be compact as possible which it does by gravitating towards larger co-moving graviton-densities. So, is seems it matters, with light-paths actually seen, that light from stars is positive-mass-originated light.

[CACBCCCU]

Question I've had is what exactly does it mean to say a massless boson is its own antiparticle? Seems the answer can also explain why any massless boson should intrinsically express its energy in a cycling of the field it propagates, why this cycling effect is fundamentally related to the energy it carries: for example with photons E = h times cycle-frequency and every phase in the cycle has an antiphase 180 deg apart and mutually anti-phased photons absorbed together destructively interfere.

[CACBCCCU]

I'm not comfortable with the idea of antimatter having a light-repelling negative mass, because photons are supposed to be their own antiparticles. On the other hand it seems to fit with the idea of antiparticles behaving like normal particles in a time-reversed way. Other than comological-scale lensing, interactions between light and matter generally are apparently not very gravity-dependent anyway, as QED works with matter and antimatter particles and doesn't involve gravity.

[CACBCCCU]

My suggestions to replace all dark matter and at least most dark energy effects are two simple counteractive-capable quantum-based corrections to gravity on the galactic scale, one correction is core-distance-dependent bi-polarly size-regulational, while the other is binding-energy related and positively size-regulational and also appears to be relevant on the high-energy small scale too. Seems to me one simple correction isn't enough here, but corrections should be simple and minimal in number.

[CACBCCCU]

There is so much dark matter effect going on that it might seem I'm saying the core has no gravitons to offer paths diverging from the spin-plane. The core can spin and spin has equatorial extrema, but that is probably not enough. What I've chosen to do is say the evenness of the 1/r^2 flux density rule is easy to emulate, especially the slower the relevant masses, with uneven flux densities, like light emission favored toward light sources, think between two cooling hot coals, but with gravity.

[CACBCCCU]

I wrote before about galaxies seeming to confine their gravitons. It's not an absolute thing, but if free-space propagating gravitons have a 60K light-year wave-cycle in their impartable effect, then a typically-sized galaxy like the milky way or Hoag's object is of nearly perfect size to do the trick on galactic-core-originated gravitons, and Andromeda is nicely-sized to do the confinement-cycle trick twice going from core to perimeter.

[CACBCCCU]

The phase-cancellation noted below is, I guess, possible with charged matter-antimatter pairs, and it also seems to effectively create a binding energy region for the pair. As a pair of spinning charges, with increasing distance from the pair, distance from each half of the pair becomes practically the same, and maybe Heisenberg's uncertainty starts to look like a confinement-assisting process as much as the opposite.

Sorry, "becoming."

[CACBCCCU]

This is becomeing the place where I put up my latest thoughts arising from the idea that gravity is fundamentally quantum and an intrinsic wavecycle of the relevant quanta is an observable in Hoag's Object and as the bottleneck shown in this video. I guess "negative mass" has issues that "negative gravity space" might not, in terms of being light-repulsive. Seems light from antimatter could exert negative light-pressure in that it could phase-cancel light from matter at the same distance.

[CACBCCCU]

Maybe I'm way off here, but it seems to me the strong force could have some basis in a gravitomagnetic binding energy on a spinning neutral matter/antimatter pair, where the zero net mass of the pair effectively confines spin energy radiation. At the moment it also seems that it's this static (but circulating) binding energy, happening in a statically-confined region within a background of a positive mass field, that is giving the effective positive mass energy to the net-zero-mass pair.

[CACBCCCU]

I meant to write that gravitons, as I suppose them, have a natural 180-degree phase shift going from a "+m" mass through ~30K ly to a "-m" mass, as ~60K ly is the full 360-degree wave-cycle noted below. Much longer cycles are possible, I suppose, 60K ly seems to be at least a lower-bound.

GR people dismiss negative mass possibility, but no definitive non-inertial (gravitational) mass result for antimatter presently exists, afaik, and I keep up with the physics news on such things daily.

[CACBCCCU]

People who claim it's been shown that positrons are attracted to the Earth are apparently basing this on a newly-discovered orbit of positrons around the planet, as if EM/G for electrons/positrons isn't 10^42 and as if positrons are the only charged particles not trapped in orbit primarily by magnetic field, and as if they've already done surveys to make sure nothing leaks away. What GR does to people is make all of this stuff pass over their heads. Whether that's positive, I don't know.

[CACBCCCU]

Suppose E^2=(m^2)c^4 is a valid starting point, meaning +m and -m are both solutions, thus gravitational mass and inertial mass need not agree in sign. Suppose bosons are their antiparticles by 180 deg phase shift separation on absorbtion, as the fields cancel. Suppose gravitons have the same 180 deg phase shift going from the +m mass through ~60K ly to the -m mass.

[CACBCCCU]

There's something about gravitons that eventually becomes apparent after considering the ~60K ly wave-cycle exemplified by the span between ring and core of Hoag's Object, and that is the galaxy seems to confine its gravitons to intragalactic paths, an effect much like surface tension at the ring perimeter. I suppose galaxies with a massive compact core are variations on Hoag's object theme, ellipticals lack the coherence such a core gives toward raising the wave pattern, it gets swamped out.
