Physics laws flawed E-mail to a Friend Monday, 10 December 2007 Swinburne University A Swinburne astrophysicist has leapt another hurdle in the path to proving that our fundamental theories of physics are not what they seem. Dr Michael Murphy is part of a team that has, over recent years, uncovered surprising and controversial evidence suggesting the laws of physics may have been changing through cosmic time. In this latest move, Murphy has debunked a study which claimed to disprove his findings. Murphy’s research into the laws of Nature goes back eight years, and concerns our understanding of electromagnetism, the force of nature that determines the sounds we hear, the light we see, and how atoms are held together to form solids. Through the study of electromagnetism in galaxies ten billion light years away, he has challenged the fundamental assumption that the strength of electromagnetism has been constant through time. “Back in 2001 we published evidence showing a small change in the fine structure constant, the number that physicists use to characterise the strength of electromagnetism,” Murphy said. “Even though the change that we think we see in the data is quite small, about five parts in a million, it would be enough to demonstrate that our current understanding must in fact be wrong. It’s an important discovery if correct. It suggests to physicists that there’s an underlying set of theories we’re yet to broach and understand.” Physicists have been chasing results like these for a number of years, but since 1999, Murphy and his co-researchers have been ahead of the pack. They’ve published a series of observations from the Keck Telescope in Hawaii as further evidence of a varying fine structure constant. But, a few years ago, another research team claimed that data from a different telescope contradicted Murphy’s observations. However, he’s been able to prove that the contradictory work itself was flawed. “We’ve shown that the way the data was analysed was faulty,” he said. “Their procedures were faulty so the numbers that came out are meaningless. Our paper points this out. When you replicate their analysis and fix their problems, you get a very very different answer indeed.” Murphy has a ‘comment’ about this latest work in this week's issue of the journal Physical Review Letters. It’s the most difficult journal for physicists to get published in, and is the one they turn to for important results in their field. This latest step is not the end of the road though in convincing scientists across the world that they need to rethink their ideas about electromagnetism. Even though this study also produced results that agree with his initial Keck findings, Murphy said there’s still work to be done. “There are some problems that need addressing,” he said. “It’s quite a surprising result and one that probably many people need a lot more convincing on. It will take some time, but we’re doing that job.”

Either electromagnetism is stronger in the past (and farther away) or the recession-dominated red-shift assumption is wrong, if I understand this correctly. So, it's a pretty dull dilemma to me.
If you use nonlinear gravity, such as the inverse-square law multiplied by a sinusoidal factor, or some such thing, I suppose the spatial energy distribution of the universe can evolve into increased complexity or, preferably, cycle within a similar periodically self-organizing path. A crudely similar process can be produced with cellular automata rules. I guess the spatial sinusoidal frequency or frequencies of quantum gravity would be most simply governed by a light-like gravity quanta mode of infinitesimal mass, and thus ultra-long wavelength, combined directly with the inverse-square rule, which of course naturally arises from the space-filling fall-off of quanta flux density with distance from the source.
Here's Hoag's galaxy:
beautiful
I've decided it's impossible to add anything more to that post, as the site- server software is apparently automatically multiplying all the paragraph breaks with each edit. Anyway, I might be the first nobody to come up with this oddball quantum gravity interpretation of the galaxy shapes seen here. I am going to name the zero-crossover region "the nobody zone." Can't wait for those internet nobody residuals to start pouring in.
Thank you for posting those. I don't see how anyone could believe it's all just from chaos.
The quantum gravity phases of Hoag's ring apparently reinforce those of Hoag's center by the distance between the two, seems to me. I can imagine glusters and intercluster space evolving to be filled with similar ripples despite no mass around to experience them. Yet if it's possible to build a Cherenkov microwave amplifier, then it seems it's possible to oscillate light using gravity, splitting it up into microwaves and thus reddening the light in the process.
I wish I understood that ;)
I don't think he expects anyone here to understand it. If you throw in enough scientific mumbo-jumbo into each sentence one has to conclude that one is either far above everyone else in intellect and knowledge, or else is a very adept bs artist (much like the typical politician that answers questions with a series of half-sentences and non-sequitors, so as to make the mind glaze over in a stupor, having forgotten the original question). Guess which of the two possibilities here I'm concluding is most likely?

Just curious, you see any of that in what I've written? Which sentence is the worst?
The way I figure it, if light and gravity particles are interrelatable, and knowing the brightness of an object has practically no effect on its mass, if light is to carry gravity, it would have to do it using an an extremely low frequency of light, meaning the effect would have an extremely long wavelength. If that wavelength is added once each cycle (once per period) of the effect on a light wave, it does not appear to explain the red-shift, to my disappointment. I haven't completely thown out the accelerating expansionary universe that the velocity-assumption red-shift indicates, or the supposed changes in electromagnetism over time, or the changes in time itself, that it seems to demand, though.
When I say I believe quantum gravity oscillates, I do not mean the force of gravity from a mass would have to oscillate if one stands still next to the mass or moves short distances around the mass. Instead, the supposed effect apparently only comes into play on a scale that is about half the distance between the middle of Hoag's ring and the center of Hoag's galaxy. That is a scale of kiloparsecs. I hedge everything with disclaimers because it's science, not politics.
Note: Where I say light I mean electromagnetic energy particles.
To put it very simply, if the graviton exists and has an extremely miniscule mass, then its de Broglie wavelength is extremely long. Also, if quantum gravity is to be combined with Einstein's cosmological constant, a reversed gravity phase must exist. Maybe the weak force's confining effect could have a similar quantum explanation operating at the de Broglie wavelength of nucleons.
