GENEVA - The research team led ICARUS Carlo Rubia who re-neutrino experiment found that neutrinos could not move faster than the speed of light.
"The results are very reassuring and told us that there was something wrong with the findings of OPERA," Rubia said as quoted by AP, Friday (16/03/2012).
September 2011, the team joined in the experiment Oscillation Project with Emulsion-Tracking Apparatus (OPERA) found that exceeding the speed of light neutrinos (300 km/sec).
Neutrinos are elementary particles with very small masses. These particles are created by radioactive decay, fusion reactions that occur in the sun or a nuclear reactor or when cosmic rays hit a group of atoms.
In a study conducted at the Gran Sasso National Laboratory, Italy, at a depth of 1,400 meters, the researchers tested the neutrinos fired from the Laboratory of the European Organization for Nuclear Research (CERN), Switzerland.
The team found that the neutrino moving OPERA 60 nanoseconds faster than light. The findings are alarming because Albert Einstein stated that no particles are moving faster than light.
Some researchers doubt the findings and consider the impossible. Many people who mention the existence of errors in both instruments and research procedures.
Another research team then tried to re-do the experiment to prove the truth of the OPERA team. One team made efforts to prove the ICARUS.
ICARUS team conducted experiments using a 600 ton liquid argon-4300 to detect the arrival of neutrinos that is sent to depth of 730 km from CERN.
Reaffirms the findings, Sandro Centro, interpreter talk ICARUS team, revealed that the neutrino velocity with the speed of light, with little deviation.
"Now we're 100 percent sure that the speed of light is the speed of neutrinos," says Centro such as the BBC reported Friday.
According to the Centro, the controversial findings of the team OPERA is the fruit of Negligence in the study, as was admitted by the OPERA team in February 2012.
Nature reported on 22 February, OPERA menyakatan that measurement error can be caused by faulty connections that affect the results of GPS readings and OPERA master clock.
ICARUS The results of a little relief, especially for those who do not believe the results of research OPERA. Now, scientists can be certain that Einstein's theory has not been refuted.
Responding to these findings ICARUS, Antonio Ereditato who is a member of OPERA said, "These results are consistent with our recent findings that there are components that do not function in our experiments."
Asked if the team was disappointed with the latest results OPERA neutrino research, Ereditato said, "This is what the science works. Whatever it is, all the advances in our knowledge globally." (kompas.com)
