Physicists Discover "Violation of a Fundamental Symmetry of the Universe"
i09.com ^ | November 3, 2010 | Staff

Posted on 11/04/2010 12:31:54 PM PDT by lbryce

Today physicists announced that they may have found the key to explaining dark matter in the universe. It all has to do with the potential discovery of a "sterile neutrino."

According to a release about the new study:
Neutrinos are neutral elementary particles born in the radioactive decay of other particles. The known "flavors" of neutrinos are the neutral counterparts of electrons and their heavier cousins, muons and taus. Regardless of a neutrino's original flavor, the particles constantly flip from one type to another in a phenomenon called "neutrino flavor oscillation."

An electron neutrino might become a muon neutrino, and then later an electron neutrino again. Scientists previously believed three flavors of neutrino exist. In this Mini Booster Neutrino Experiment, dubbed MiniBooNE, researchers detected more oscillations than would be possible if there were only three flavors.

"These results imply that there are either new particles or forces we had not previously imagined," said Byron Roe, professor emeritus in the Department of Physics, and an author of a paper on the results newly published online in Physical Review Letters.

"The simplest explanation involves adding new neutrino-like particles, or sterile neutrinos, which do not have the normal weak interactions."

The three known types of neutrino interact with matter primarily through the weak nuclear force, which makes them difficult to detect. It is hypothesized that this fourth flavor would not interact through the weak force, making it even harder to find.

The existence of sterile neutrinos could help explain the composition of the universe, said William Louis, a scientist at Los Alamos National Laboratory who was a doctoral student of Roe's at U-M and is involved in the MiniBooNE experiment.

From the article;
That's right - we've either discovered a new particle, a new force, or the universe is fundamentally flawed. And we may be a few steps closer to understanding all the matter we haven't yet discovered, and have therefore labeled "dark."

If there's a fourth flavor of neutrino that doesn't interact through the weak force, then ALL RELIGIONS ARE WRONG.

You have to define "symmetry of the universe". "Symmetry" implies "perfect symmetry" which implies for every action, there is an equal and opposite reaction. But that can only be to attempt to "maintain symmetry" so symmetry can never be.

Just some wild thoughts from my wild mind.

This would be better understood by the general populace if they referred to it as the "John F. Kerry oscillation".

If they don't figure this out, the universe could collapse on itself in twenty billion years. This crisis calls out for a new stimulus program in 2011.

Please note they have “discovered” no such assymetry, nor have they discovered the “sterile neutrino” which they hypothesize might exist. This is a possible explanation, they know practically zip.

It's not sloppy work if God does it ~ Einstein used to say God doesn't play dice with the universe.

Of course Einstein was wrong ~ God does play dice with the universe, particularly when He throws them where He can't see them.

But, we digress. They've found something they think they might could understand someday so they've proposed a theory ~ yet another neutrino. Maybe it's a buttino, and it's hot, and cold, at the same time!

That’s what ‘theories’ and ‘hypotheses’ are supposed to be for - to test against reality, to be proven, changed, or scrapped as the data indicate...

NOT to be defended with doctored data, so they can be used to justify policies which will bankrupt nations.....

There are plenty of asymmetries in Physics: for instance - there’s an asymmetry that causes there to be more matter than antimatter.

Asymmetries are not signs of sloppy work: they’re merely what they are: asymmetries .

Your house, your body, your dog, your planet, the night sky - all of these are either subtly or obviously asymmetric, and yet all of them are good. The subatomic world is equally asymmetric - and it works beautifully.

God is an perfectionist, and makes all things better than we can know.

"Symmetry" implies "perfect symmetry" which implies for every action, there is an equal and opposite reaction. But that can only be to attempt to "maintain symmetry" so symmetry can never be.

If the universe existed in perfect symmetry, we'd have a universe full of gamma rays and nothing else. It's the asymmetry that gave rise to matter.

And for what it's worth, I always considered "dark matter" to be the astrophysicists' equivalent of "dragons" on old world maps. Might as well say "The Force Formerly Known As Prince".

Strange indeed. A quick check shows neutrinos to be both massless and yet travel at the speed of light. At the same time, they must have mass in order to oscillate their flavor. Neutrino flux also affects the decay rate of isotopes - the half life used for carbon dating for instance. That blows up that technique for dating past events. Bottom line, the more they know, the less they know about it.

Special department of unobservable phenomenon kudos here.

The article actually says:
And we may be a few steps closer to understanding all the matter we haven't yet discovered, and have therefore labeled "dark."
Actually, it's called "dark" matter because it does not interact with electromagnetic fields (like light). Our preception of the universe is primarily through electromagnetic radiation or the effects of electronic interactions (touch) and, ultimately, sound. (Sound is only explainable in terms of electronic properties of matter.) Neutrinos were originally "discovered" in the negative: to account for the missing mass/energy and momentum in subatomic particle interactions. "Dark" matter was never any more mysterious than positing particles that behaved in some ways like neutrinos, but weren't like neutrinos, at least like the ones we know about. (Dark matter was "discovered" in an attempt to account for gravitational effects not explainable by the observed mass in the universe, i.e., discovered in the negative.)
