Physics by means of particles of a neutrino has measured the mass of Earth


For this purpose scientists used the neutrinoes given from the detector. The result a little in what differed from received in the traditional way. The group of the Spanish physicists has established the mass of Earth, using the neutrinoes given from the detector. Writes Science Alert about it. New results a little in what differed from those which have been received in earlier traditional way - 5,972E24 of kg. Neutrinoes are the most widespread particles in the Universe, however to find them quite difficult. Almost always the mass of these particles is equal to zero because they interact with normal matter very little, proceeding through the Universe with a speed which is brought closer to light. Neutrinoes have been open for the world thanks to the detector IceCube, and using his data, scientists could study Earth interior. During work scientists used the quantity of a neutrino registered by the detector for calculations. First of all were interested physicists the atmospheric neutrinoes which are given rise in the top layers of the terrestrial atmosphere. Occasionally these particles nevertheless interact with substance, and traces of it amplify the detector. Researchers used data of observatory from 2011 to 2012. To calculate density of layers of Earth, they have counted how many neutrinoes could pass through the planet under different corners to IceCube. It is known that to this case measurement of mass of Earth and its density was carried out on the basis of gravitational field and indications of seismic detectors. Earlier it was reported that scientists have declared a probable complete recovery of an ozone layer of Earth by 2030. News from the Correspondent.netv of Telegram.
