As computed, the neutrinos' average time of flight turned out to be less than what light would need to travel the same distance in vacuum. In a two-week span up to November 6 , the OPERA team repeated the measurement with a different way of generating neutrinos, which helped measure travel time of each detected neutrino separately.
Thus, they should travel at exactly the speed of light, according to special relativity. However, since the discovery of neutrino oscillations, it is assumed that they possess some small amount of mass. [1] Thus, they should travel slightly slower than light, otherwise their relativistic energy would become infinitely large. This energy is ...
In September 2011, OPERA researchers observed muon neutrinos apparently traveling faster than the speed of light. [8] In February and March 2012, OPERA researchers blamed this result on a loose fibre optic cable connecting a GPS receiver to an electronic card in a computer.
According to the theory of special relativity, the question of neutrino velocity is closely related to their mass: If neutrinos are massless, they must travel at the speed of light, and if they have mass they cannot reach the speed of light. Due to their tiny mass, the predicted speed is extremely close to the speed of light in all experiments ...
In September 2011 OPERA researchers reported that muon neutrinos were apparently traveling at faster than light speed. This result was confirmed again in a second experiment in November 2011. These results were viewed skeptically by the scientific community at large, and more experiments investigated the phenomenon.
Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light in vacuum (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons ) may travel at the speed of light, and that nothing may travel faster.
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
The CERN Neutrinos to Gran Sasso (CNGS) project was a physics project of the European Organization for Nuclear Research (CERN). The aim of the project was to analyse the hypothesis of neutrino oscillation by directing a beam of neutrinos from CERN's facilities to the detector of the OPERA experiment at the Gran Sasso National Laboratory (LNGS ...
