Retest of neutrino speed suggests Einstein was right, after all

Six months after physicists shocked the world by announcing they'd found particles seemingly traveling faster than light, the growing scientific consensus seems to be that the results were flawed. Neutrinos are the vampires of physics. Researchers at the ICARUS project in Italy have recreated an independent version of the original Switzerland-based experiment, called OPERA, and found that their particles traveled at a respectable, sub-light speed.

Though the results don't automatically disprove OPERA's findings, they add to most scientists' sense that the shocking finding was an anomaly "The evidence is beginning to point towards the OPERA result being an artifact of the measurement," Sergio Bertolucci, research director at the CERN physics laboratory that houses OPERA, said in a statement.In September, baffled physicists from the OPERA collaboration announced that they'd sent beams of particles called neutrinos from CERN, in Geneva, to a detector buried underground 454 miles (730 kilometers) away in Gran Sasso, Italy, and found that they arrived 60 billionths of a second sooner than light would have.

Such a finding is incredible, because the speed of light was thought to be a cosmic speed limit imposed by Einstein's special theory of relativity. The OPERA scientists were as surprised as anyone, and invited other researchers to scrutinize their results and recreate their experiment to help prove or disprove their findings.

Now ICARUS has, and the results suggest neutrinos might be more mundane than they briefly seemed.

"The ICARUS experiment has provided an important cross-check of the anomalous result reports from OPERA last year," said Carlo Rubbia, spokesperson for the ICARUS experiment. "ICARUS measures the neutrino's velocity to be no faster than the speed of light. These are difficult and sensitive measurements to make and they underline the importance of the scientific process."

Darnit.

Have to retire the joke now:

Bartender: “ We don`t serve ur kind in here.”

A Neutrino walks into a bar.

I, for one, am relieved.

Not cool. I was looking forward to being pre-Obama.

Almost the life of a nutreno...

I was married to a widow, who was pretty as can be.
This widow, had a grown-up daughter,
Who had hair of red.
My father fell in love with her and soon they too were wed.
This made my dad my son-in-law,
And really changed my life.
Now my daughter was my mother,
Cause she was my father’s wife.
And to complicate the matter,
Even though it brought me joy,
I soon became the father of a bouncing baby boy.
My little baby then became a brother-in-law to dad,
And so became my uncle, though it made me very sad.
For, if-if he were my uncle, then that also made him brother.
Of the widow’s grown up daughter, who was of course, my stepmother.
Uh huh.
Father’s wife then had a son who kept them on the run,
And he became my grandchild, for he was my daughter’s son.
My wife is now my mother’s mother, and it makes me blue.
Because although she is my wife, she’s my grandmother too.
God.
Now, if my wife is my grandmother, I am her grandchild, yeah.
And every time I think of it, heh! Nearly drives me wild.
Cause now I have become, the strangest case you ever saw,
As husband of my grandmother, I am my own grandpaw.
Oh I’m my own grandpaw.
I’m my own grandpaw.
It sounds funny I know, but it really is so,
Oh I’m my own grandpaw.
I’m my own grandpaw.
I’m my own grandpaw.
Talk about incest!
It sounds funny I know, but it really is so,
I’m my own grandpaw.

I’m pretty much always going to side with Einstein on these questions.

I was just thinking about that photo.

So what did we learn and how much did it cost?

Everytime we conduct neutrino experiments we learn about the Sun,supernovas,black holes,the beginnings of universe and what makes it up. It is Government funded, it is part of the European Council for Nuclear Research and private sponsors.

Here are the list of private sponsors:

Speaking of neutrinos, someday we may be able to use them to communicate with our subs:

The ignorant media grabbed at this useless but sensational story without a clue that experimental results have to be repeatable.

In this case, further testing showed otherwise, that it was a measurement problem.

The neutrinos were generated by a particle beam traveling just less than the speed of light, with neutrinos being stripped off by a magnetic field.

Any child throwing a piece of gum out of a car window knows that the gum can never go faster than the car.
