September 23th, a new has mad the scientific community tremble. Researcher CERN’s researchers based in the INFN Gran Sasso laboratory in Italy have measured a beam of neutrinos which was faster than light. This observation was invalided by the ICARIUS experience on mars 16th. But this is not the end of the story…
Let me tell you the fantastic story of the neutrinos
Once up on a time (15 billion years ago), soon after the birth of the Universe, a promising particle named Neutrinos is born. It has some quality that could help it to win the race with the light. First of all, neutrinos are so small that the scientific, F. Reines, says that a neutrino is “the most tiny quantity of reality ever imagined by a human being”. This particle don’t interact with other particle, it is free of charge, unaffected by magnetic field. It is only affected by the weakest of nature’s force, which is the gravity. This means that a neutrino can go straight away thought the universe, Stars, Galaxies, magnetic fields as if those one didn’t existed.
What’s a neutrino? You still do not understand? Don’t panic it would take only one minute and 25 seconds for you to become a neutrinos’ expert.
Now that you are more familiar with neutrinos, let’s continue the story.
September 23th 2011, Antonio Ereditato, Spoke person and Dario Autiero, coordinator of the experience OPERA announced that they have observed a neutrinos that was faster than light.
This result was like a bomb in the scientific community. It could blow up all the established physics’ laws and contradicted the Einstein’s relativity theory which claims that noting is faster than light.
This observation did not only threat to tremble the scientific edifice, but also to change our conception of the universe and of the causality. Indeed, if a neutrino could run faster than light, it means that it would be able to transport information in the past. It could change the course of event. For example, you could send to your past person the result of the lottery and become rich. This means that human would have to admit that there is no causality and no order in the universe.
This unexpected discovery make a lot of people react all around the internet. Lots of comments were posted. Some were wondering if it was possible, other were dreaming and debating about time traveling.
By their side, scientists were sceptical about this unexpected discovery and decided to wait for the result of independent researches. They were tweeting all around the world.
Soon the OPERA’s results were infirmed. Mars 16th 2012, researchers from the ICARUS experience held in the Gran Sasso laboratory found as result that neutrinos are not able to run faster than light. According to a CERN’s press release, the error come from the optical fiber connector that routes the signal to the external GPS master clock OPERA which could have not operate properly when the measure was taken.
Hearing these result two persons where specially reassured. It is Jim Al-Khalili and the ghost of Einstein.
But this is not the end of the story, CERN’s experiences such as BOREXINO, ICARUS, LVD and OPERA are currently doing measure which will lead to a final verdict. Until then it is still allows to dream of time traveling or to do nightmare about universe’s chaos.
