Physicists struggled for decades with neutrinens mystery: the theoretical calculations of how many neutrinos produced was not consistent with the measurements of the earth. Up to two thirds of the neutrinos were missing.
Japanese Takaaki Kajita and Canadian Arthur B. McDonald solved the conundrum when they separate experiments discovered that neutrinos had swapped identity. This discovery made it possible to conclude that neutrinos must have mass, something not previously thought.
“The discovery has changed our understanding of the innermost and can prove vital for our picture of the universe, “writes the Royal Swedish Academy of Sciences in the press release.
The previous standard model of the innermost was based on the neutrinos had no mass. Nobel laureates discovery has shown that the standard model can not be the complete theory of the universe’s basic components.
neutrinos are the second most common elementary particles universe, second only to photons. They are created in nuclear reactions in the sun’s interior and in the reactions between cosmic rays and the Earth’s atmosphere.
