Multumesc pentru link mai ales ca separat de ce semnalezi se gaseste acolo si articolul referitor la masa neutrinilor premiul Nobel fiind dat pentru: The 2015 physics Nobel Prize goes to the discoverers of the strange ability of neutrinos to transform among three “flavors.”

In addition to explaining the solar neutrino deficit,
these discoveries implied that neutrinos are not massless—according to theory, oscillations are only possible if there are differences in mass between the three flavors. It’s not yet known what these masses are, but they are very small, at least a million times less than the electron mass. And yet neutrinos are so numerous that they add up to a mass roughly equivalent to that of all the luminous matter in the Universe. Moreover, because the standard model is predicated on massless neutrinos, new theories will be required to explain why they have mass, so the discoveries of McDonald, Kajita, and their teams, point to future directions in physics research. Close says there are several current urgent questions regarding neutrinos, such as their potential connections with the mysterious dark matter and with the puzzling asymmetry between matter and antimatter.
