There May Be A Fifth Force of Nature, Study Suggests (space.com)

According to a paper published in the journal Physical Review Letters, physicists at the University of California, Irvine, may have discovered a previously unknown subatomic particle that's evidence of a fifth fundamental force of nature. Space.com reports: "[Professor of physics and astronomy Jonathan Feng] and his colleagues analyzed data gathered recently by experimental nuclear physicists at the Hungarian Academy of Sciences, who were trying to find 'dark photons' -- hypothetical indicators of mysterious dark matter. Dark matter is thought to make up about 85 percent of all matter in the universe, but it neither absorbs nor emits light, so it's impossible to detect directly. 'The experimentalists weren't able to claim that it was a new force,' Feng said. 'They simply saw an excess of events that indicated a new particle, but it was not clear to them whether it was a matter particle or a force-carrying particle.' The new work by Feng and his team suggests that the Hungarians found not a 'dark photon' but rather a 'protophobic X boson' -- a strange particle whose existence could indicate a fifth force of nature. The known electromagnetic force acts on protons and electrons, but this newfound particle apparently interacts only with protons and neutrons, and then only at very short distances, researchers said. The potential fifth force may be linked to the electromagnetic and strong and weak nuclear forces, as 'manifestations of one grander, more fundamental force,' Feng said. It's also possible that the universe of 'normal' matter and forces has a parallel 'dark' sector, with its own matter and forces, Feng added. 'It's possible that these two sectors talk to each other and interact with one another through somewhat veiled but fundamental interactions,' Feng said. 'This dark-sector force may manifest itself as this protophobic force we're seeing as a result of the Hungarian experiment. In a broader sense, it fits in with our original research to understand the nature of dark matter.'"

Locke2005 writes: I've always speculated that there might be forces of nature that we never observed because they were on a much larger or smaller scale than we could detect easily. But now Jonathan Feng, a professor of physics and astronomy at the University of California, Irvine, is suggesting there may actually be a fifth force. Of course, this might vanish just like the Higgs Boson evidence did. Can anybody explain better what it was they detected, and why it is being interpreted as evidence of a previously unknown force?

      Further, we know what the "fifth force" is: we call it Dark Energy.

      Once upon a time Feynman gave a lecture explaining how we knew there wasn't a fifth force, because a very precise experiment had been done to measure the attraction between two objects, and it was exactly what we expected from gravity. No mystery left to explain.

      Well, two ways that can be wrong, and it looks like he might have been wrong in both ways: a force which was simply to weak to measure by any earthbound experiment, or a force which simply doesn't affects the objects measured (wooden spheres IIRC). The former is dark energy - it's so weak at human scale, or even at the scale of our galaxy, that you'd never see it. As for the latter: we still don't really know how dark matter works, and maybe it has its own forces (some oddball ones have been proposed).

      Asserting that we "know" that dark energy is a fifth force, in the same sense as the other four forces in the Standard Model, is claiming more than we actually know at this point. Maybe it is, but there are no good theories at this point that make it one, and it could be something quite different from the particle/force models physicists have been working with.

And you'd have to explain at some point why e.g. the Coulomb interaction doesn't demonstrate it as a direct augmentation of Coulomb interactions and meso-scale deviation from 1/r^2 form with its much greater (and hence easier to observe) interaction strength.

      Standing waves in EM fields (where we can easily observe them in e.g. lasers, Fabry-Perot interferometers, etc) require reflectors at both sides of a cavity. They arise out of solutions to a wave equation with specified boundary conditions on surface(s) bounding a volume. We do not USUALLY observe them as steady state phenomena between individual pairs of particles or objects, in part because the objects would scatter an incoming wave, not reflect it back in the direction that would (eventually, after a retarded time) be the location of the source. The scattering results in incoherence. It is very difficult to see how a linear wave theory could give rise to an effectively nonlinear resonant alteration of gravity with large numbers of incoherent sources in any of the usual models of dispersion or resonant interaction, let alone one that has the right properties to explain the observations.

      So, if you are a math/physics/field theory uber-geek (I'm not, I'm just a humble ordinary physicist and this is over my pay grade:-) you could always give it a try and try to build some sort of model of your hypothesis, after doing enough research that you can establish how to even start, but as I said, my intuition based on a fairly detailed knowledge of ordinary EM waves is that -- probably not worth the time. One MIGHT argue that a dense galactic center (or a black hole at the center) could form a kind of effective "boundary" for such a wave, but the increasingly dispersed stars and other matter surrounding the galaxy do not seem to be good candidates for a second boundary.

      If you want an idea that seems MORE likely to be fruitful, imagine that the black hole is radiating quantized gravity waves in all directions, and that those outgoing waves, as they pass physical matter, stimulate the coherent emission of more gravity waves in the one-pass phenomenon (observed and actually exploited in E&M) known as "coherence brightening". We actually observe coherence brightening in astrophysics, IIRC, when light from a distant source passes through excited stardust (that is, for example, ionized by nearby stars.

      But this still doesn't quite work for me -- for one thing what "excites" stars so that they can add energy to a gravitational wave (which has to carry energy, after all)? Why doesn't the surrounding matter act more like a dielectric and SCREEN the gravitational field, if anything? It's hard to know how to even begin to build a theory of gravity per se that could explain the galactic rotational anomaly, and I think many very competent people have tried and continue to try.

The best that can be said for or against fifth force theories in physics is that there is little sound evidence to support any specific one of them. At the same time, there is AMPLE evidence that our knowledge of physics is incomplete, and there are large scale, clearly visible phenomena (like the galactic rotational anomaly and other cosmological observations) that strongly suggest that there is indeed SOME sort of additional force or interaction present beyond the four we know of, as we cannot (so far) see any way to explain what we see within the confines of those theories.

      Is it a "fifth force"? Is it "dark matter" and/or "dark energy"? Well, if it is the latter, it IS a fifth force, at least, unless somebody manages to come up with a particle outside of the existing elementary particle zoo that doesn't couple to any of the forces but e.g. gravity itself. However, physical particles usually couple to the physical forces in some way so a completely new particle is not unlikely to be associated with a completely new force.

      The point is that I don't BELIEVE in such a thing -- few physicists do -- in the absence of evidence to support such a belief. I think the theory of magnetic monopoles is absolutely lovely -- they would fill a tremendous gap in our knowledge of physics, they would symmetrize Maxwell's Equations in a way they are begging to be symmetrized in, they would explain the quantization of charge -- but I, like most physicists, will only BELIEVE in monopoles when somebody reproducibly puts salt on the metaphorical tail of not one, but a steady stream of monopole observations. Ditto the Higgs particle. Ditto "trans-luminal neutrinos". Experimental evidence talks, theoretical bullshit walks -- or more reasonably, waits in the wings as a plausible hypotheses not yet supported until experiments are performed that increase the probability that they are correct (incorrectly stated as "confirm" them, just as a lack of evidence or negative evidence doesn't necessarily "refute" them).

      I don't quite get your point about the Bible, either. Yes, the Bible is bullshit, with pretty much ever line of its supernaturalism refuted by ordinary common sense and all of the evidence worthy of the name we've ever collected. (To provide an interesting metaphor -- suppose all four gospels reported Jesus as saying "I have seen the magnetic monopole in my water turned into wine." Would any reasonable person then conclude that monopoles are proven to exist beyond any reasonable doubt based on a single, 2000 year old observation of them reported as hearsay by individuals who were not there and who reported nothing of the experimental method used, the error bars, the controls against fraud perpetrated just so one could get tenure... bearing in mind that turning H_2O lacking carbon and nitrogen into a complex of ETOH and lots of flavorings and particulate matter made up of proteins and hydrocarbons is even more ludicrous than observing a monopole without any visible apparatus or method) Quite a lot of its supposed history is unsupported by actual archeological evidence -- it is more in the category of "legend" shading over into "myth" than it is "history". But belief in the absurd in the context of the Bible is in no way comparable to the process of formulating hypotheses and searching for corroboratory evidence in cutting edge physics. Even theorists who propose the theories usually know better than to "believe" in them -- they do the work in the hope that experiments will be done (guided by their work, perhaps) that validate their hypotheses or correct them and give them new insight.

This is a concrete statement, and if you disagree, feel free to actually post your way of proceeding. It wasn't argument, as I'm neither asserting that there is or isn't a fifth force, dark matter, monopoles, a useful standing wave theory of gravitational waves, or for that matter a meaningful "time theology" whatever that might be -- I'm just pointing out that using the terms in their usual sense it isn't easy to see how to explain the galactic data using standing gravitational waves, or even to see how (necessarily monochromatic and coherent) standing gravitational waves could come about.

      The place where physicists DO argue is at conferences and workshops, usually where they disagree about some aspect or another of mathematics or experiment in an area of physics that is not yet resolved into probable/accepted provisional truth. I've been in the middle of one of those and it wasn't pretty. How CAN one explain things like conditional convergence of series to somebody that already ought to know it? But in the end, the mathematics and sound reason usually win, because (unlike time theology) there is actually a unique answer and we have an objective method for homing in on it.

      Probably not actually. To get a good standing wave you need something that will reflect gravity waves well, and there really isn't anything that will do that.

      An alternative might be boundary conditions for a closed universe, but with inflation there really isn't time for a gravity wave to have crossed the entire universe. Before the time of inflation it might be barely possible. That would be something that people would be looking for in the cosmic microwave background data.

What the relevant quantised parameters are for understanding gravity waves remains a topic of serious study - it's the whole research direction of "quantum gravity". I just searched ARXIV for "quantum gravity" and got 600 total hits for the last year. Not a subject I'm going to try to get up to speed on without someone paying me a decent salary - that's understanding 3 papers a day for a year, just to be a year out of date. And they're all assuming that gravity is quantised, even if arguing about how it is quantised, or the consequences.

      Given what we know about the quantisation of the fields of the electroweak force and the strong force, it would be most surprising if the gravity field were not quantised. However, given the extreme weakness of the gravity field (I can overcome the gravity of 10^23 grammes of the Earth with the electroweak power of a couple of kg of leg muscle!! That's a factor of about 10^20 ; and the strong force is similarly stronger.), the technological hurdles to measuring that quantisation are significant.

      Not an argument from me, this is really the point I was making. Gravity waves we observe are the moral equivalent of the classical EM waves emitted by a radio. Sure, somewhere in there there are photons, but they are in a state or mixed state that utterly obscures their quantum nature (and there I actually did a fair bit of work upon a time and have a PR paper on nonlinear quantum optics in the master equation/langevin approach).

      So, without trying to unify quantum field theory -- which is what coming up with the right theory of gravitation is all about -- that somehow also is consistent with general relativity, the original question I responded to was whether or not "standing gravitational waves" were responsible for the alteration of ordinary 1/r^2 gravitation OR the excess mass creating ordinary 1/r^2 gravitation. All I then did was point out that it seems unlikely, even without a detailed theory, on the grounds of similar phenomena in the EM field where the "weak" component is more or less irrelevant to the opposition of super-weak gravity -- a point I make every three or four months to a new crop of introductory physics students btw. It takes an entire planet to pull us down with our weight. It takes the combination of electrostatic force and the Pauli exclusion principle to oppose that weight with a thin skin of structured charged particles (where nuclear and electroweak are important on the inside of atoms, but the actual force managing the repulsion is all fermionic electrons).

      That doesn't make it impossible. The EM force is modified at short range by (quantum) virtual pair production and the polarization of the vacuum. One can imagine, at least that the vacuum is polarizable in some way to gravitation, although it is a bit difficult given that we are only aware of a single "pole". At least some phenomena in EM also alter measurably when one makes bound states out of things, creating bands of states instead of "ideal" sharp lines -- I'm not sure how that would apply to gravitation as gravitational bound states are the moral equivalent of purely classical EM orbits but without the strong radiation of energy that was predicted by Maxwell and that was part of the downfall of Newtonian mechanics. Sure, the moon presumably radiates away gravitational energy every time it orbits the earth, but the effect is so miniscule that it is overwhelmed by tidal coupling that drives the moon AWAY from the earth every year by a few cm, the exact opposite of a radiation spiral.

    New chemical Element Discovered
    by William DeBuvitz

    The heaviest element known to science was recently discovered by investigators at a major U.S. research university. The element, tentatively named administratium, has no protons or electrons and thus has an atomic number of 0. However, it does have one neutron, 125 assistant neutrons, 75 vice neutrons and 111 assistant vice neutrons, which gives it an atomic mass of 312. These 312 particles are held together by a force that involves the continuous exchange of meson-like particles called morons.

    Since it has no electrons, administratium is inert. However, it can be detected chemically as it impedes every reaction it comes in contact with. According to the discoverers, a minute amount of administratium causes one reaction to take over four days to complete when it would have normally occurred in less than a second.

    Administratium has a normal half-life of approximately three years, at which time it does not decay, but instead undergoes a reorganization in which assistant neutrons, vice neutrons and assistant vice neutrons exchange places. Some studies have shown that the atomic mass actually increases after each reorganization.

    Research at other laboratories indicates that administratium occurs naturally in the atmosphere. It tends to concentrate at certain points such as government agencies, large corporations, and universities. It can usually be found in the newest, best appointed, and best maintained buildings.

    Scientists point out that administratium is known to be toxic at any level of concentration and can easily destroy any productive reaction where it is allowed to accumulate. Attempts are being made to determine how administratium can be controlled to prevent irreversible damage, but results to date are not promising.

    I'm not sure what you're getting at with ''random" as a causal factor

    My suggestion, in brief, is that for any case in which one can attribute causality to "random" (or "probability distribution"), one can equally ascribe it to "God". "Random" cannot be broken down into constituent scientific causal factors--that would be a self-contradiction. A deterministic random. It is, in that sense, wholly outside of scientific method, and an "appeal to random" has no more or less scientific validity than an "appeal to God". This includes such things as the origin of the universe, individually improbable macro-scale QM effects (otherwise termable "miracles"), and other counterintuitive phenomena we observe, such as quantum entanglement.

    Occam's beliefs are relevant in that he correctly applied his Razor, which contrary to common incorrect restatement, does not make any claims to determine the likelihood of a particular model's correctness, or exclude his own theistic model.

    All else being absolutely equal between two competing models, Occam's Razor specifies that the simpler model be used -for the purposes of conceptual economy-. The simpler model is used because it is simpler. That implies greater ease of further use in analysis, again, all else being completely equal.

    It speaks to a model's straightforward use, not its preferability as representing fact. Were that the case, scientific progress would come to a halt, because in the great majority of cases (i.e. Newtonian physics), the simpler model is simply the inaccurate one.

    "Presumptive path" would be a separate heuristic from what Occam's Razor addresses, and I suggest care in not conflating the two such that one's argument is equivocating from "useful" to "true".

    Breaking news: Due to concerns of racism, fourteen top research universities in the United States and Europe have banned the term "Dark Matter" stating that "it denigrates minorities as it equates darkness with being unobserved and unnoticed while at the same time making up most of the universe. The current discourse serves only to entrench White Supremacy and White Privilege, it has to be stopped." They have recommended that scientists instead use the term "Matter of Darkness" and that the scientific literature stop preferring so called "ordinary matter" over "Matter of Darkness".

    They also recommend that instead of forcing matter into 'baryonic' and 'non-baryonic', which they allege are social constructs, that matter be allowed to form it's own identity free from the Cis white heterosexual orthodoxy.

    "This move isn't anti-science in any way", writes prominent Feminist scholar and advocate Anita Sarkeesian, "this is about equality for all matter, not just Matter of Darkness. Why is one form of matter preferred over another, if not because of the patriarchy?"

    Despite the reservations held by those in the scientific community, the universities are standing firm and have stated their intentions to withhold funding for researchers who refuse to abide by the new guidelines.

    Meanwhile Twitter has been abuzz with hashtags both promoting the move such as #NonBaryonicLeptonsMatter and #YesAllWIMPS.
