PUZZLER BY NAME. “The process by which this inequality between matter and antimatter particles developed is called baryogenesis.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

THE PUZZLER. “There is strong evidence that the observable universe is composed almost entirely of ordinary matter, as opposed to an equal mixture of matter and antimatter. This asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

PERIODIC ANTI-TABLE. “Physical principles indicate that complex antimatter atomic nuclei are possible, as well as anti-atoms corresponding to the known chemical elements.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

SMALL STEP. “The nuclei of antihelium have been artificially produced, albeit with difficulty, and are the most complex anti-nuclei so far observed.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

ATOMIC ASSEMBLY. “Antimatter particles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom.” https://en.m.wikipedia.org/wiki/Antimatter View in LinkedIn

ANNIHILATION. “If surrounding matter is present, the energy content of this radiation will be absorbed and converted into other forms of energy, such as heat or light. The amount of energy released is usually proportional to the total mass of the collided matter and antimatter, in accordance with the notable mass–energy equivalence equation, E=mc2.” 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

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
