Supersymmetry? --"Standard Model of the Universe Fails to Explain Dark Matter or Dark Energy"

The Standard Model is the mainstream theory of all the fundamental particles that make up matter, and the forces that govern them. But the model has weaknesses: it doesn't explain dark matter or dark energy, which jointly make up 95 percent of the universe. Nor is it compatible with Einstein's theory of general relativity the force of gravity as we know it does not seem to work at the subatomic quantum scale.

However, in a new blow for the futuristic "supersymmetry" theory of the universe's basic anatomy, experts reported fresh evidence Monday of subatomic activity consistent with the mainstream Standard Model of particle physics. New data from ultra high-speed proton collisions at Europe's Large Hadron Collider (LHC) showed an exotic particle dubbed the "beauty quark" behaves as predicted by the Standard Model, said a paper in the journal Nature Physics.

Previous attempts at measuring the beauty quark's rare transformation into a so-called "up quark" had yielded conflicting results. That prompted scientists to propose an explanation beyond the Standard Model possibly supersymmetry.

But the latest observations were "entirely consistent with the Standard Model and removes the need for this hypothesis" of an alternative theory, Guy Wilkinson, leader of LHC's "beauty experiment" told AFP. "It would of course have been very exciting if we could show that there was something wrong with the Standard Model I cannot deny that would have been sensational," he said.

Supersymmetry, SUSY for short, is one of the alternatives proposed for explaining these inconsistencies, postulating the existence of a heavier "sibling" for every particle in the universe. This may also explain dark matter and dark energy. But no proof of supersymmetric twins has been found at the LHC, which has observed all the particles postulated by the Standard Model including the long-sought Higgs boson, which confers mass to matter.

Supersymmetry predicts the existence of at least five types of Higgs boson, but only one, believed to be the Standard Model Higgs, has so far been found.

Wilkinson said "It is very difficult to kill supersymmetry: it is a many-headed monster." But "if nothing is seen in the next couple of years, supersymmetry would be in a much harder situation. The number of true believers would drop."

Quarks are the most basic particles, building blocks of protons and neutrons, which in turn are found in atoms.

There are six types of quarks the most common are the "up" and "down" quarks, while the others are called "charm", "strange", "beauty" and "top."

The beauty quark, heavier than up and down quarks, can shift shape, and usually takes the form of a charm quark when it does.

Much more rarely, it morphs into an up quark. Wilkinson's team have now measured for the first time how often that happens.

"We are delighted because it is the sort of measurement nobody thought was possible at the LHC," he said. It had been thought that an even more powerful machine would be needed.

The revamped LHC, a facility of the European Organisation for Nuclear Research (CERN), was restarted in April after a two-year revamp to boost its power from eight to 13, potentially 14, teraelectronvolts (TeV).

"If you expect Earth-shattering news from the new run, it's a bit early," CERN director-general Rolf Heuer told journalists in Vienna Monday at a conference of the European Physical Society.

"The main harvest will come in the years to come, so you have to stay tuned."

So far, the new run at 13 TeV has re-detected all the Standard Model particles except for the Higgs boson, but Heuer insisted: "We are sure that it is there."

So Quark's bar is still in business?
Sorry - just could not resist. :)

Our Universe is a larger version of a galactic polar jet.

"The universe was born spinning and continues to do so around a preferred axis"

Our Universe spins around a preferred axis because it is a larger version of a galactic polar jet.

'Mysterious Cosmic 'Dark Flow' Tracked Deeper into Universe'

"The clusters appear to be moving along a line extending from our solar system toward Centaurus/Hydra, but the direction of this motion is less certain. Evidence indicates that the clusters are headed outward along this path, away from Earth, but the team cannot yet rule out the opposite flow. "We detect motion along this axis, but right now our data cannot state as strongly as we'd like whether the clusters are coming or going," Kashlinsky said."

The clusters are headed along this path because our Universe is a larger version of a polar jet.

It's not the Big Bang; it's the Big Ongoing.

The mass which fills 'empty' space is beginning to be referred to as the 'dark mass' in order to distinguish it from the baggage associated with dark matter.

"That is, all that we are certain about [is] the dark mass, not dark matter, let alone to say about the dark 'particle'."

Dark energy is dark mass continuously emitted into the Universal jet.

The Milky Way moves through and displaces the dark mass.

The Milky Way's halo is the state of displacement of the dark mass.

The Milky Way moves through and curves spacetime.

The Milky Way's halo is curved spacetime.

The state of displacement of the dark mass is curved spacetime.

So once again the LHC upholds the standard model of particle physics rather than overturning it as was hoped by the WIMPy crowd, so maybe it's time to examine an alternative baryonic model of dark matter. (How ironic to have to call an ideology relying entirely on the standard model of particle physics an alternative model.)

(Assuming an absence of non-baryonic dark matter) if 4/5 of the baryons had condensed into gravitationally-bound proto-spiral-galaxies during the epoch of Big Bang nucleosynthesis (BBN) (promoted by isothermal gravitational collapse mediated by endothermic helium fission), then the intergalactic photon-to-baryon ratio and the intergalactic baryon density of the universe could be as measured and calculated with 80% of the nucleons sequestered into proto-spiral-galaxies. Then the sequestered baryons merely extended the duration of the epoch of BBN during proto-spiral-galaxy 'BBN rebound'.

Ditto for baryon acoustic oscillations (BAO) if 4/5 of the baryons had been sequestered into gradationally-bound proto-spiral-galaxies.

Then imagine that the epoch of reionization was the condensation of the hydrogen and helium continuum into gravitationally-bound (Bok) globules, promoted by isothermal gravitational collapse mediated by endothermic molecular hydrogen dissociation and hydrogen ionization.

Then in the intervening 13 billion years, (Bok) globules cooled to become the coldest objects in the universe, with their luminous stellar metallicity frozen (sequestered) into icy chondrules, leaving the remaining molecular hydrogen and helium at circa 10 Kelvins virtually invisible.

Sticky (Bok) globules cluster into gravitationally-bound dark matter (DM) 'globule clusters' on highly-inclined halo orbits, but the DM globule clusters on the shallowest halo orbits are exposed to high doses of stellar radiation which sublimes icy chondrules, rendering them opaque. And (high molecular weight) gaseous stellar metallicity lowers the speed of sound through the globule, promoting Jeans instability. So dark matter globule clusters on the shallowest halo orbits decloak to become 'giant molecular clouds' on their way to becoming star clusters.

Thus there never was a 'cuspy halo problem' if DM globule clusters simply convert to stars and hot gas in regions of high stellar concentrations like globular clusters (which have no dark matter) and galactic bulges (which have far less dark matter than the 'cuspy' concentrations predicted by WIMPy models).

here is the truth...proof of previously undiscovered magnetic field properties which scale from galactic,solar sys,planet/moon (magnetic fields),chemical/molecular bonds,atomic particles....and so on...A true unified field....I welcome an expert opinion.
