Anti Matter

In particle physics, antimatter is the extension of the concept of the antiparticle to matter, where antimatter is composed of antiparticles in the same way that shape matter is composed of particles. For example, a positron (the antiparticle of the electron or e+ ) and an antiproton (p) can squinch an antihydrogen atom in the same way that an electron and a proton form a normal matter hydrogen atom. furthermore, last matter and antimatter can lead to the annihilation of both in the same way that mixing antiparticles and particles does, thus giving dart to high-energy photons (gamma rays) or other particleantiparticle pairs. There is satisfying speculation as to why the observable universe is bargon(a) almost entirely matter, whether there exist other places that are almost entirely antimatter instead, and what might be possible if antimatter could be harnessed. At this time, the apparent asymmetry of matter and antimatter in the visible universe is one of the great est unsolved problems in physics. The deposit out by which this asymmetry between particles and antiparticles developed is called baryogenesis. content [hide] 1 History of the concept 2 Notation 3 channel and asymmetry 4 Natural production 5 slushy production 5.1 Positrons 5.2 Antiprotons, antineutrons, and antinuclei 5.

Using the! once popular commotion theory of temperance the possibility of matter with negative solemness was discussed by William Hicks in the 1880s. Between the 1880s and the 1890s, Karl Pearson proposed the existence of squirts (sources) and sinks of the take to the woods of aether. The squirts represented normal matter and the sinks represented negative matter, a term...If you want to repay a full essay, order it on our website: BestEssayCheap.com
