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.”

I've been trying to keep up with new theories for over 30 years, with only a few years of majoring-curriculum college physics at a state university in the midwest under my belt as part of my BSEE. Physics is just a hobby, in other words. Being able to speed read and having the reading comprehension level and pace reflective of my 176 LSAT score helps.

I have thought for a while that the Earth's gravity must have been much less in the past, which accounts for the size of the dinosaurs. If it hadn't been, why aren't such large animals around now?

I have a concept of local universe creation where two membranes are twisted and wrapped together like a cloth being wrung out, then suddenly it rips everywhere and all these cosmic strings come flying out. I guess there are these so-called membranes normally spaced apart by quantum gravity, but the ordering is eventually compressed by surroundings. I suppose there's a system of re-priming for local cycles globally, one that involves an ultra-cold phase. With nonlinear gravity, heat death in this universe need not be a random distribution but could instead form ultra-cold superconducting sheets. No explanation is required, let alone a complicated one, for the existence of energy that has always been, in one form or another. Life is the most complex and nuanced thing going on anywhere inside, or supposedly outside, the global universe, in this way it is the cream of reality. Whether our creations will eventually eclipse us is the most intriguing question I can think of at the moment.

I'm smart enough to know that today elephants approach the limit for the size of land animals. The only way dinosaurs could have existed in the past is if gravity was less.

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.

I suppose red-shifting has something to do with interaction between electromagnetic quanta and gravity quanta which only shows up on an ultra-long scale corresponding to wavelengths of an ultra-low-mass gravitational quantum.

What I'd like to be able to do is show a transformation path between electromagnetic quanta and gravity quanta. It would seem to require nothing more than multiple amounts of both types of quanta configured in some way.

I've read that book, around 1972.

School always bored me, like I'd get into trouble in trig class for cracking jokes. Liked very few teachers in high school, got a lot of Bs and sometimes worse. Did best in my last two years of college, after changing majors from chem-e and changing schools, taking time off for full-time work, and then finally getting serious about it. Seems like it took me almost forever to graduate.

Yes, it most certainly is. I'm glad you like it. The tiny red galaxy with a little ring, at about 1 o'clock in the dark-ring region of Hoag's galaxy, is apparently manifesting an Einstein ring - you might notice there's a tri-corner pattern spanning and modulating the tiny ring's brightness. Not sure if the region its light passes through is an influence in the formation there, but it seems an unusual coincidence. Clear even-shaped Einstein rings usually have something much closer to them, something that's massive, usually very bright, and slightly off the visual axis. I mean I don't see what could be making the Einstein ring of the tiny galaxy behind Hoag's galaxy, except Hoag's galaxy itself. I believe quantum gravity should be weaker than Newtonian/Einsteinian gravity in the dark region, and that it includes a narrower circular region of gravitational repulsion, a galaxy-generated ring-shaped locus behaving as if it's an anti-gravity source, although more precisely, according to this scenario, it's a zero cross-over point of quantum gravity waves from the massive center. Gravity becomes much more Newtonian/Einsteinian again on each side of that region.

At lower resolution, Hoag's galaxy is reminiscent of the Sombrero galaxy in infra-red, turned sideways.

The forum software is buggy and inserting paragraph breaks like wild on each edit, BTW.

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.

I start with a steady-state universe assumption, because it neatly (and profoundly, I believe) avoids any creation-centered logical contradictions. A steady-state theory also has more freedom besides that it obviously has more time, it can encompass infinite energy, it easily includes multiverse theories, and it can be boundless or bounded. With infinite energy and infinite time a stable global cycle can have infinite absolute period, meaning it can be significantly aperiodic and infinitely non-repetitive while preserving all the benefits of stability and periodicity. Just from a steady-state assumption there is an incentive to question an all-recessionary red-shift assumption, but the steady-state universe assumption still does not preclude it. Most of the quantum gravity aspects I've suggested here do not require a quantum gravity red-shift, nonetheless a divergence between quantum gravity and classical- Einsteinian gravity is apparently the only thing capable of creating a significant distance-dependent red-shift that is nonrecessionary. I suppose galactic-intergalactic distributions have significantly evolved toward maximizing intergalactic quantum gravity zero-crossing zones, giving a red- shifting graviton-coupled quantum ripple to much of intergalactic space. As the local universe (meaning the observable universe) cools from its creationlike phase, the regularity of galactic spacing should increase, along with the intergalactic red-shifting effect. It all continues cooling and organizing into a more massive pattern of multi-cluster quantum gravity-spaced strata until nonlocal universe conditions rush in to re-wind the process. In turn, this universe has a universe re-cycling effect on the nonlocal universe. These different creationary heating phases of the parts are somewhat similar to rain patterns, except that it is not driven extra-globally but is eternal, with no beginning or end, which is the definition of a steady-state universe. Exactly how it all balances is, by this particular approach, at least partly due to a balance between gravity and anti-gravity phases of a quantum gravity wave.

Here's a line-up of some Einstein rings. If the smaller reddish (or much more distant) galaxy showing through Hoag's galaxy has an Einstein ring, it appears to be most similar to the one at the top left corner. I still can't figure out exactly what's going on there at the moment, so Hoag's galaxy may or may not have anything to do with the smaller galaxy ring behind it. The ring does appear to be the inverse of the ring I picked out of the group in a number ways, including brightness distribution and relative light-frequency, meaning it is perhaps redder, not bluer, than the center object the small ring frames (which is the lensing object), and brighter where the selected Einstein ring is darker, both of which makes it seem possibly influenced by anti-gravity instead of gravity. To me at the moment it looks like it could be called an anti- Einstein ring, which is a hilarious idea. Always a bonus. More specifically it seems it could be a lensing that is anti-gravity lensed, a combination of a normal gravity lens (concave?) with an inverse (convex?) gravity lens in front of it. The image of the smaller galaxy almost seems drawn into the ring like the magnetic flux threading through an air-core inductor.

Hoag's galaxy and its more-distant through-threaded neighbor galaxy image again, for comparison with the Einstein rings:

It may be the light-source being supposedly lensed there is just below and far behind the small galaxy, and the threading of both sources through Hoag's anti- lens has enhanced the rings.

Yes. It's not just from chaos if its matter and energy once went through a cooling phase where quantum gravity re-organized it before it was re-heated.

Haog's object apparently presents the first identified example of an achromatic-type doublet (1 concave + 1 convex) gravity lensing system.

I guess one could say it is an air-spaced doublet, since the two lensing galaxies involved are far apart.

Seems I am the first nobody to identify this.

I don't doubt that we have very much to discover about physical laws. Very much indeed.

Personally I think we are due for a major breakthrough in physics and cosmology.

No, I haven't. Does it mention quantum gravity? I tend to think light and matter are basically eventually decomposable into gravitons, in some sense. How one goes from supposedly spin-2 particles (gravitons) to spin-1 particles (photons) is what I was thinking I should understand. Not sure if gravity can be carried outside of photons if the lowest possible photon energies (frequencies) are considered, but supposedly it can. Could a pair of photons be a graviton? I don't know. A photon (gamma ray) can be transformed into an electron-positron pair, usually quickly self-annihilating. If there are multiples of such electron-positron pairs nearby, a pair may not end up being quickly annihilated inside the bunch. From light thus one gets stable particles, and they have mass, supposedly a source of gravitons. That, I guess, closes the simplest photon-graviton transformation loop.

A sufficient amount of separated anti-matter could run for a while in its own loop, the same way as matter does, I suppose. Maybe that is responsible for accumulations of so- called "dark matter." I could envision the supposed re- organizational effect of quantum gravity is to stratify anti-matter and matter on cosmological scales mostly separately but still intermixedly, towards forming a sort of ultra-long standing wave. By my way of looking at it, all this scenario requires a preceding phase of massive non-local (cosmologically- speaking) (re)compression forces if significant amount of matter and anti- matter are to separately (re)accumulate.

I should've written "from outside the observable universe" rather than "non- local" there. I'm trying to keep my comments here close to cosmological ideas and non-locality in quantum physics is mostly a separate subject. I do like to shift my focus around, though, so maybe I can add something on some other thread. The link mentions holographic theories in physics, and there is a holographic theory relating black holes and information in string theory, IIRC. Holographic storage, annealing (with quantum gravity, an annealing process could occur on a cosmic scale) and neural nets are all related topics, perhaps interestingly enough.

The structure, dynamics and evolution of stars is a complex field I know practically nothing about.

I may be wrong about the lensing capability of Hoag's galaxy, but I'm relatively sure that it is framing an Einstein ring in the open portion, and I may have the basic quantum gravity aspect of Hoag's galaxy correct.

The idea of a quantum gravity redshift is also a bit less sure than the basic idea of quantum gravity undergoing phase-reversals, which I think is being used elsewhere, though I have not seen it applied to explain any galaxy's appearance.

Einstein rings are usually bluer than the lensing object, although I have seen some other distant Einstein rings from Hubble that are red. The Einstein ring image held within the opening in Hoag's galaxy appears to be quite large and well defined for as red as it is. That is why I get the impression that Hoag's galaxy is gravity-lensing the Einstein ring system in a unique way.
