Cultural Project faster than light neutrinos By GejingXu
Faster-than-light neutrinos? • Last year, a team of CERN physicists observed neutrinos traveling faster than the speed of light, but now it looks as though this extraordinary measurement might be the result of a loose fiber-optic cable or a poorly calibrated atomic clock
Explain of neutrinos • The neutrino is a lepton, one of the fundamental particles composed of the natural world, the neutrino mass is very light, less than one millionth of the electrons. • The neutrino has the strongest penetration. So thick the material across the diameter of the earth, only one in 10 billion neutrinos in with the material response, therefore, the neutrino is also known as the "Invisible Man" in the universe. Neutrinos continue to decay after launch, the quality becomes very small, it is only in theory can run the speed of light particles
continue… • Tiny neutrinos may have broken cosmic speed limit(September 23,2011) • The neutrino news came from a group of physicists based at the Gran Sasso underground laboratory in Italy and doing business under the apt acronym Opera. The neutrinos, they reported on Sep.23 in a paper and at a special symposium at CERN, The European Center for Nuclear Research, had beaten a metaphorical light beam from CERN to Gran Sasso, a distance of 457,by 60 nanoseconds.
Is it a mistake? • The initial response of physicist assembled at CERN and around the world was that there was probably a mistake somewhere in the experiment. Einstein’s theory is the basis of all modern physics, and has been tested a zillion times.
Why it was considered a mistake • Technically, relativity does allow some particles, known as tachyons, to go faster than light-in fact it forbid them to slow down to light speed. The hitch is that they would have imaginary massed, whatever that means. And there is also the possibility, in some versions of string theory, of particles’ taking a shortcut through another dimension. But allowing anything to travel faster than light would open up the possibility of all kinds of problems with cause and effect and even time travel.
It is hard to consider as a mistake • John learned, a neutrino physicist at the university of Hawaii, wrote in an e-mail that while the opera result might not be right, “they are still not easily dismissed”
If it does exist • If there do exist a neutrino that can travel fast than the speed of light then the law of Einstein was break. • The law is the cosmic speed limit declared in Albert Einstein’s theory of special relativity in 1905
The Einstein • Einstein’s Special Theory of Relativity, which underpins the current view of how the universe works, says that nothing can travel faster than light, and doing so would be like travelling back in time
Why particles can not travel fast than light Energy goes up as velocity increase.
The impact of the neutrino • Bertolucci, director of research at CERN, said that if this study is validated, it will change the human concept of the physical. • Give people the thought that science come from right and goes to the mistake. Science was the process of correcting the exist concepts.
Make people thinking • Is there truly something can travel fast than light. • There will be spacecraft travel fast than light? • People will use this spacecraft to travel to other planet? • Was Einstein wrong?
Bring new concept to people’ mind • The actors in films often act that as they travel fast than the speed of light, then they go back to history, is that true? • In accordance with Einstein's theory of relativity is able to reach this conclusion, because the theory of relativity that the speed of light is the fastest in more than the speed of light will appear to catch up with the phenomenon of time, that is, turn back the clock
The future physics • May be in the future people will break the relativity and people can travel fast than the light and the they act just like what the film was acting. • Hope one of us will be the scientist that breaking the relativity.
