can anyone explain me what is antimatter?

Answer 1

Anti matter is when the electrons and protons in an atom switch their magnetic charge.

Answer 2

All matter is basically shaped in the most efficient Geometry, which is a spherical shape. The outer skin of matter is what contains it.
If a particle at certain frequency collide with the spherical shape matter,it may knock it out of its containment,
The spherical shape of the skin still remains intact.So here we have creation of two structure of mass matter; One is the skin structure (antimatter),and the other is what remains of the internal structure(matter).
So every mass structures are both composed of matter and antimatter to form mass in its spherical shape contaiment.
An example =Electron being the mass matter, and anti-electron which is called positron being the anti- matter.
Even though when a particle is separated from its matter and anti matter component parents the resulting particle structures are short lived as they quickly collide and break up into the basic micromass structure which will fly out at the speed of light.The whole process result in what is called Energy.
This has been experimentally observed when electron matter and positron antimatter collide.This is a good example how energy is created.
Note;a charge is a particuluar amount of mass structure existing in a mass containment volume.
If the process was undertaken on a large scale using a magnetic containment ,Energy can be harnessed for the good of man kind and may solve energy problems.

Answer 3

Antimatter is the same as matter except it has the complete opposite charge as matter. Take the electron for instance--in matter it contains a negative charge. In antimatter it contains a positive charge (and is called a positron).

Answer 4

Matter which consists of antiparticles, elementary particles of ordinary matter, such as protons and electrons, but have an opposite electrical charge. For example, an antiproton has a negative charge while a proton has a positive charge. When a particle of matter and a particle of antimatter come into contact with each other they are destroyed, releasing energy.

Answer 5

While I agree with the explanation of antimatter, it is no longer a theory. It's existence was confirmed back in the 1930s, and more recently has been synthesized in small amounts (atomic level) for brief periods of time (nanoseconds).

Answer 6

A very simple explanation is that early in the Big Bang there was only energy and no mass or matter. Einstein proved that energy and mass can be converted from one to the other and back and forth per E=mC2. Some of the original energy was converted simultaneously into fundamental particles and their anti-particles (think of that as perhaps right and left-handed threaded bolts?) that separately flew off into space. If the particles ever meet again they will annihilate each other reproducing the original energy that produced their mass. It is believed that particles far outnumber anti-particles in the universe today (perhaps due to an original imbalance of one type particle). After countless annihilations particles dominated anti-particles. Both particles and anti-particles can be produced or observed in the lab today.

Answer 7

antimatter is matter composed of elementary particles that are, in a sense, mirror images of the particles that make up ordinary matter as it is known on earth.

Answer 8

Mandy got it right. When a positron and an electron collide they vanish into a gamma ray which is pure energy and a gamma ray has been observed decaying back to being an electron and a positron.

Answer 9

Let's say in this world of ours, antimatter is to matter what yin is to yang...
