antimatter

One of my friends was talking about antimatter in school today in school and would not stop, just to bother me, because I didn't know what antimatter was. What IS antimatter?

I'm so werid (^_^)

ANTIMATTER or contra- terrene matter is matter that is composed, of antiparticles of those that constitute normal matter.IF a particle and its antiparticle come in, contact with each other thay will annihailate, and produce a burst of energy. BASICALY electromagnetic radiation will be made. ALSO I got this info from wikipedia.com/ IN laymans terms you can say, that electromagnetic waves are radio waves.

Antimatter= a complete opposite of a given element. As of now, CERN is only able to produce an anti-particle of Hydrogen. Antimatters have electrons in their nucleus instead of protons. And the protons are the ones revolving around the nucleus and are called positrons. If an anti-matter comes in contact with its counter-part matter, it will transform in to energy, and may likely be turned into light particles.  |

antimatter refers to subatomic particles. it is believed that the periodic table of elements reflects the behavior of materials composed of antimatter, but this is not yet fully explored experimentally. personally, i shy away from using the word "opposite" to describe anti-particles. rather, they have complimentary behavior. it is not true that an antiparticle is the ABSENCE of a particle in space, as may be inferred by the word "opposite".

*nods* isn't it a possibility that based on the stability differentials of antimatter, wouldn't that theory basically be used to create a new form of energy, other than coal, electricity, solar power, wind power, nuclear power, and gasoline? -just a thought... (*thinks about the materials in nuclear power formulas and nods*)

The energy produced through anitmatter annihilation is massive If we cant even contain nuclear fusion, using energy produced by antimatter annihilation will be quite improbable Also, antimatter is present in very small and rare amounts in the universe and are extremely difficult to produce on earth although scientists have postulated the existence of areas in the universe that are composed entirely of antimatter... But I think its possible in the near future =) |

Since atoms of antimatter are overwhelmingly outnumbered by regular matter, it would be rare to find indeed. If, during the formation of the universe, a cluster of antiparticles gravitated together, they would exist as a cloud of condensing dust unless they encountered matter. The problem is, during the time when atoms of hydrogen and anti-hydrogen were first starting to be produced by the cooling of the infant universe, the proximity of the two would have resulted in very complete annihilation of all emergent antiparticles. Now, in a universe of stars (opposed to that of dense hot energy) it would be more likely for NEW antiparticles to condense into antimatter in significant amounts, something less likely during an infant universe. For this reason, the number of antiparticle clusters out there is limited by the production of new positrons and anti-protons. I do not know much about the production of these particles, but I do know that they can be the byproduct of certain hi-energy collisions. Maybe there are some star systems out there that have certain properties, allowing for an accumulation of isolated antimatter which we could "farm" for energy. It would be nice!

Antimatter can be produce by virtual particle productions, where a regular particle and its anti-particle just "exist" in a vaccuum and then destroys each other. http://en.wikipedia.org/wiki/Virtual_particle The reason why the universe has matter instad of anti-matter might be due to CP-violation, in which baryon numbers are not conserved (the theory is analogus to the conservation of mass, which is broken...) http://en.wikipedia.org/wiki/CP-violation While it may be possible to have a cluster of anti-matter in the universe (nothing said it can't happen), it is very unlikey as it will require an isolated vaccuum fairly removed from any presence of matter, which is generally what the universe is. |
