COSMIC ANTIMATTER. “Most matter observable from the Earth seems to be made of matter rather than antimatter. If antimatter-dominated regions of space existed, the gamma rays produced in annihilation reactions along the boundary between matter and antimatter regions would be detectable.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

CREATED IN COLLISIONS. “Antiparticles are created everywhere in the universe where high-energy particle collisions take place. High-energy cosmic rays impacting Earth's atmosphere (or any other matter in the Solar System) produce minute quantities of antiparticles in the resulting particle jets, which are immediately annihilated by contact with nearby matter.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

ANTIPARTICLES. “They may similarly be produced in regions like the center of the Milky Way and other galaxies, where very energetic celestial events occur (principally the interaction of relativistic jets with the interstellar medium).” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

INTERGALACTIC ANTIMATTER. “The presence of the resulting antimatter is detectable by the two gamma rays produced every time positrons annihilate with nearby matter. The frequency and wavelength of the gamma rays indicate that each carries 511 keV of energy (that is, the rest mass of an electron multiplied by c2).” (E=mc2). https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

ANTIMATTER CLOUD. “Observations by the European Space Agency's INTEGRAL satellite may explain the origin of a giant antimatter cloud surrounding the galactic center.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

ANTIMATTER CLOUD. “While the mechanism is not fully understood, it is likely to involve the production of electron–positron pairs, as ordinary matter gains kinetic energy while falling into a stellar remnant.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

DISTANT SOURCE. “Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

INDISCERNIBLE. “Antimatter galaxies, if they exist, are expected to have the same chemistry and absorption and emission spectra as normal-matter galaxies, and their astronomical objects would be observationally identical, making them difficult to distinguish.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn
