Detected particles whose velocity is greater than the speed of light?



Physicists have discovered that the particles of light (photons) can live about 1 trillion years, and after the collapse of isolated, in turn, are very light particles that can travel faster than light! Over time, many particles are subject to natural decay. For example, unstable radioactive atoms at some point break down into smaller particles and emit energy boost.

Just recently, scientists believed that photons do not fall, because it was thought that they have no mass. Nevertheless, scientists now believe that photons have mass just is so small that it can not be measured using modern appliances.

The current upper limit on the mass of the photon is so small that it is less than one billionth, billionth, billionth of the mass of the proton. On the basis of this indicator, scientists have calculated that a photon in the visible spectrum can live about 1 trillion years. However, the extremely long life is not common to all of the photons, it is calculated on the average. There is a possibility that some photons are living very little. Our universe emerged in the Big Bang, is now about 13.7 billion years old. And the ongoing research projects are designed not only to measure the afterglow of the Big Bang, but also for the possible detection of early signs of decay photons.

If the photon to break, resulting in the collapse should stand out even more light particles, those who are able to travel in our universe is faster than the speed of light. These ghostly particles (neutrinos) are very rarely interact with ordinary matter. Countless neutrino fluxes are racing each fraction of a second, not only through the vastness of space, the stars and the body, but through every living person in the world, while not affecting our matter.

In the decay of a photon out two light neutrinos, which, being lighter than light, photons move faster. The discovery of neutrino seemingly violates the law of the theory of relativity that nothing can travel faster than light, but it is not, because the theory is based on the fact that the photon has no mass of the body. In theory, states that no particle can travel faster than the massless particle.

In addition, the theory of relativity assumes that the particles are moving very quickly, being in a time warp space. That is, if they had a mind, they would have the impression that everything that happens around them is in a very "slow motion." This means that in our time space photons should live about 1 trillion years, and in their time stream — only about three years.
