Scientists at the world's largest physics lab say they have measured subatomic particles called neutrinos that travel faster than light. If true, it would put into question Albert Einstein's special theory of relativity.
According to the laws of physics, nothing can go faster than the speed of light. But leading physicists have measured particles that don't exactly obey that law.
Researchers at CERN laboratory in Switzerland have measured particles traveling faster than light, putting into question Albert Einstein's 1905 theory of special relativity.
According to the famous equation, E equals mc2. Theoretically, particles traveling in a vacuum shouldn't move any faster than the speed of light. The concept is central to our understanding of physics and time.
The particles were measured during the OPERA experiment. The experiment involved neutrinos that were sent from CERN in Geneva to a laboratory hundreds of miles away in Italy. Let's just say, the particles showed up a tad earlier than they should have.
Neutrinos are elementary particles that usually travel close to the speed of light. The particles are electrically neutral and interact gravitationally with other particles. They also switch types spontaneously.
The BBC reported that CERN scientists observed a particular type called muon neutrinos, and tracked the particles to see how many traveled to the lab in Italy and turned into tau neutrinos.
In the experiment, a neutrino beam was fired from a particle accelerator in Geneva to a remote laboratory in Italy. That's when the researchers couldn't help but notice that the particles traveled 60 nanoseconds faster than the speed of light.
However, CERN researchers are still waiting on others to confirm the findings. Scientists at T2K in Japan and MINOS near Chicago in the United States are on the case. If the results are confirmed, the laws of nature will certainly be refined to reflect this discovery.
It could be a discovery or be a systematic error. It's too soon to tell at this point.
"This is ridiculous what they're putting out," Drew Baden, chairman of the physics department at the University of Maryland, told the Associated Press. "Until this is verified by another group, it's flying carpets. It's cool, but ..."

This question may sound bit naive but my question is how did the researchers are sure that the neutrino they detected in Italy was the same one generated in Geneva and not other neutrinos that was in the surroundings. I would reallya ppreciate if some one can clarify this to me
1. These laws of physics are "Ours", not "The". We perceived them, we wrote them. 2. We don't know jack. 3. We probably will never know jack. The system doesn't seem to be designed to allow that. It is - at its core - self-preservationist. 4. This article is a good example of why SmartPlanet articles need to be a little longer. Did anyone tell Boonsri that Mark already wrote something on this (with about the same level of depth)? 5. I liked your article better :-)

Maybe e=m(vn)-squared, where vn is the velocity of neutrinos. (Why does the post lose the superscript "2" that I coded in?)
So perhaps we don't have all the answers after all? This is proof that we actually are getting smarter - or at least they are, not me. When I look at everything I learned in school and how all of those books have now been rewritten as we've learned brand new facts and figures we didn't know before, it proves we're only as smart as we were yesterday. Einstein also said we must first ask the question. We still are and we're still learning. It's a great day indeed.
If we look at our minds purely as a type of machine as we perceive them, then our minds are inextricably tied to these so-called laws of physics. It is a bio-mechanical device that runs on electricity. But, if we take one more step back, there is much more behind our perception of what mind is. Whatever ultimately drives our collective needs is the *impetus* for our minds to functional mechanically. Don't think it's possible to ever really know, though. That day of enlightenment will probably kill us off.
The good thing about having e-books today is that they can update them at speed light, and even if we are a little bit slower now, we can almost keep updated with the new discoveries.
