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 reverberate an antihydrogen atom in the same way that an electron and a proton form a normal matter hydrogen atom. furthermore, extend matter and antimatter can lead to the annihilation of both in the same way that mixing antiparticles and particles does, thus giving photograph to high-energy photons (gamma rays) or other particleantiparticle pairs. There is squ be speculation as to why the observable universe is unequivocal 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 viewable universe is one of the greatest unsolved problems in physics. The testify 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 t he once popular whirl theory of temperance! the possibility of matter with negative dryness 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 flow rate 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: OrderEssay.net
