Scientists from Germany, Italy, Russia and Sweden found out next to Earth the particles of antimatter of high energy. The source of particles while is not set, but, on one of versions, there can be a dark matter them. Astrophysics, workings with a space vehicle PAMELA, investigated arriving from space anti-particles. Anti-particles differ from an ordinary matter an electric charge and magnetic moment – and in all other their properties coincide fully, reports "Newspaper".nesmotrya
on likeness between an ordinary matter and antimatter (from which it is even possible to build the atoms and molecules), is alongside they do not can with each other. At meeting of particle and anti-particle they annigiliruyut, growing into a radiation. Annihilation of gramme of antimatter
will give energy, equal to energy of explosion at once of three bombs in Hiroshima: on this property of antimatter the subject of recently going out film is built «Angels and demons» - conspirators going the antimatter stolen from a laboratory to blow up Vatican.Predicted Weed
By Dirac in 1928 and opened on experience in 1932 of antimatter it would it was be in Universe so much, how many ordinary – from point of physicists between them there is not an of principle difference. Then, why our Universe practically does not contain an antimatter – one of to
this pores of the not settled riddles. To decide its scientists going including by looking after not numerous anti-particles which it can find out all the same: PAMELA registered antiprotons and positrons (anti-particle of electron) from 2006, and recently astrophysics
published a next report on the work.Researchers studied the stream of particles, arriving with high speed. Energy of these particles made an over milliard electron-volt: such electrons on Earth it is possible to get only in the most powerful accelerating. And stake
among particles appeared an antimatter unusually great, there were more than ten positrons on one hundred electrons, such correlation simply specified on some unknown source of antimatter. On the role of such source of physics offered two candidatures.
First are pulsars: tailings of stars, compressed in a ball by a diameter about 20 kilometres and with a closeness, near to the closeness of kernels of atoms (tea spoon of matter on mass pre
antimatter – but at that rate somewhere there must be the pulsars yet not opened by astronomers.The second variant of origin of anti-particles is disintegration while of not found out the particles of dark matter. We will remind that scientists estimate mass of dark matter as exceeding
mass ordinary tenfold, and it was recently succeeded to find out that a dark matter is saved there, where and ordinary matter. In an order to check up this hypothesis of astrophysics already began supervisions with the use of other space vehicle – gamma-teleskopa
«Fermi». Vehicle, which from a summer 2008 years used for supervisions in gamma-diapazone (radiation, arising up during annihilation gets exactly in gamma-diapazon) able to make clear nature of particles, found at a help PAMELA.pomimo mass and electric charge,
elementary particles have a row of other properties. A magnetic moment determines the conduct of particle in the magnetic field. A few parameters (spin, giperzaryad, «color» and even «oddity») are entered in quantum physics and determine co-operation of particles with each other.Energy
particles determined the same as and energy of usual bodies is depends on speed. Physicists measure it in electron-volts – energy in 1 ev is got by an electron, flying between two contacts with the difference of tensions in one volt.To get an antimatter in a laboratory
possibly, but only in insignificant amounts. The cost of one gramme of antimatter will exceed the budget of the USA for one hundred years – therefore about application of antimatter as a weapon or fuel for the spaceships of speech does not go. But one of types of radiation – beta-izluchenie
– just is the stream of positrons and used in medicine for a tomography.
