Skip to comments.Physicists Discover "Violation of a Fundamental Symmetry of the Universe"
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.

I Knew that! 8)
This discovery is unto something as it would account for the whole damn Obama phenomena.
Just some wild thoughts from my wild mind.
Boy, you can say what you want about “Geeks”, but they must be smoking some wierd stuff. And to think I started out as a Physics major in the late 50s. Things were so simple then.
Neutrino’s have been made “Nacho Cheesier”?
I’m waiting for the article that says that all matter has a shelf life and we have reached it.
This would be better understood by the general populace if they referred to it as the "John F. Kerry oscillation".
So they they are saying either there is something they do not understand, or God does sloppy work.
I pick the former.
Will it someday be discovered that we never really existed?
What will we do on that day?
It must be time for the scientists to request more federal grant money. “We can’t allow this question to remain unresolved!”
That Nobel prize is supposed to me mine!!!!
Mine!!! Mine!!! Mine!!!
***and have therefore labeled “dark.” ****
Jessie and Al is gonna get you sucka!
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.
That’s quite a bit much to ponder, contemplate that we don’t really even exist. :-)
The Law of Mass Conservation states that”
“mass can neither be created nor destroyed”
(All matter exists... somewhere.)
New discovery: The Universe will come to an end in 5-4-3-2...
neutrino? Isn’t that a wild rodent in Florida? Or a Italian cookie, a figaro neutrino?
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!
I thought we were done with Helen Thomas threads.
I see a screen name but I see no evidence of you...
You must have missed the thread re; scientists
(used loosely) who posited that one day - time will cease.
They failed to state unequivocally which day that would be:
Monday, Tuesday or Wednesday.
I hope that was satire. lol.
Every new discovery seems to throw their old theories out the window. lol.
"What do you get if you multiply six by nine"?
"Six by nine. Forty two."
"That's it. That's all there is."
"I always thought something was fundamentally wrong with the universe."
You are obviously a student of the ‘string cheese’ theory;)
Things were so simple then.
Yep, and the pay was a lot less. I wonder how much these guys make. Anyway, I liked the simple life.
how does one know it’s a new flavor if one can’t taste it?
” Every new discovery seems to throw their old theories out the window. lol. “
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.....
It isn't really a violation of anything until Congress says it is............give them time and they probably will.
Yeah; It’s like the scientists who’ve claimed to have invented a device that stops time but haven’t decided on the duration in which to test it out.
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.
Ow, my head hurts.
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".
Special department of unobservable phenomenon kudos here.
So glad to have made your day.
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.)
No, mesons are now on par with the neutrino.
They are now parmesons..............
By its “oscillations” (no stripper jokes, please).
What will we do on that day?
Since we wouldn't exist, by definition, nothing.
May the Schwartz be with you.
2 x 2 = 5 for extremely large values of 2
Funny thing after I read this I remember thinking the same thing the other day and pondering on whether I should publish it or not. I finally opted to go get a banana split instead. Obviously I made the right decision!!!
