what is an anti-matter ?
912086
(m)\n\nMatter 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.

we are human beings made of complex carbon compounds which are made of basic particles molecules which are agin made of electrons and protons and nuetrons which are again made up of quarks..............we are livng in this universe with reason tha twe see the way it is.........its as per the basic anthropic principal............now as far as being existing in terms of pairs let me explain you...\nwe live in universe which is made of particles and antiparticles every particle has a corresponding antiparticle.  A particle and its antiparticle have identical mass and spin..now these both carry various as per earths scientist have designed such as electric charge, color charge, flavor, electron number, muon number, tau number, and baryon number. so if go into deep into this it will be difficult to understand..... so we exists in pairs...so check out man to see whether ur anti of yours.you will be annhilited man.....so better be careful...one another approch is the many world theory which states us that there are many parallel universes around they depend upon the every action do in present i guess.....its also called as catastrophe if you know.....\nso there u go that swhy we r not alone and only one....\nregarding the last two this called as world as our english dictionary given a name to this earth the other name....and if you dnt who you are then you better stop watchin movies like matrix..........and all that crap....hope u understand the answer.........live life bye.......

In physics, matter is commonly defined as the substance of which physical objects are composed, not counting the contribution of various energy or force-fields, which are not usually considered to be matter per se (though they may contribute to the mass of objects). Matter constitutes much of the observable universe, although again, light is not ordinarily considered matter. Unfortunately, for scientific purposes, "matter" is somewhat loosely defined.\n\nSee http://en.wikipedia.org/wiki/Matter for more information on matter.\n\nGood Luck!!!

If Anti- Gravity means repulsions between two gravitational masses;then the answer to this excellent question exists.\nFirst if we look how gravity affects atomic elementary particle we could understand anti-gravity.\nThere is a point lets say where the gravity field between the electron and proton intersects in such a way that a repulsion occurs.This shows that no two particle can actually come togheter and stick to each other.So particle integrity is maintained.The phenomena of anti gravity is real.This is in full agreement with experiments in qunatum mechanics, which have shown repulsion between particles.

Hi bornsmartgal\n\nThe antimatter created in the very early universe annihilated with matter created at the same time.  When a matter particle and its antimatter counterpart meet the annihilate and produce energy (eg a collision between an electron and positron produces two back to back photons).  In the early universe there was a small over abundance of matter over antimatter (one billion and one matter particles for every one billion antimatter particles).  After the annihilation this leaves matter left over (plus a billion photons for every matter particle!)\n\nThis initial over abundance of matter over antimatter is puzzling - the difference between matter and antimatter is a reversal of charge and particle physics is largely symmetrical to charge reversal. Physicists have been looking for an asymmetry in nature which will explain the over abundance, and have finally found a few such events (called charge-parity symmetry violations).  It appears nature isn't totally symmetrical after all.\n\n\nHope this helps!\nThe Chicken

Atom smashing. In high-energy head-on collisions between particles such as protons some of the energy will be converted into particle-antiparticle pairs. The antiparticles are, of course, antimatter.

Antigravity, but that hasn't been proven.  Magnetism works when you have two magneticaly charged objects.

The definations wanted by you are given below-\n\nIn physics, matter is commonly defined as the substance of which physical objects are composed, not counting the contribution of various energy or force-fields, which are not usually considered to be matter per se (though they may contribute to the mass of objects). Matter constitutes much of the observable universe, although again, light is not ordinarily considered matter. Unfortunately, for scientific purposes, "matter" is somewhat loosely defined.\n\nMass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.\n\nAn elementary particle is a particle with no measurable internal structure, that is, it is not a composite of other particles. They are the fundamental objects of quantum field theory. Elementary particles can be classified according to their spin, with fermions having half-integer spin and bosons integer spin.\n\nSpace has been an interest for philosophers and scientists for much of human history. The term is used somewhat differently in different fields of study, hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. Disagreement also exists on whether space itself can be measured or is part of the measuring system. (See Space in philosophy.) Many fields use an operational definition in which the units of measurement are defined, but not space itself.\n\nIn chemistry and physics, an atom (Greek  átomos meaning "indivisible") is the smallest particle of a chemical element that retains its chemical properties. \n\nA chemical element, often called simply an element, is a substance that cannot be decomposed or transformed into other chemical substances by ordinary chemical processes. All matter consists of these elements and as of 2006, 117 unique elements have been discovered or artificially created. The smallest particle of such an element is an atom, which consists of electrons centered about a nucleus of protons and neutrons.\n\nIn chemistry, a molecule is an aggregate of two or more atoms in a definite arrangement held together by chemical bonds. Chemical substances are not infinitely divisible into smaller fractions of the same substance: a molecule is generally considered the smallest particle of a pure substance that still retains its composition and chemical properties. Certain pure substances (e.g., metals, molten salts, crystals, etc.) are best understood as being composed of networks or aggregates of atoms or ions instead of molecular units.\n\nIn particle physics, antimatter extends the concept of the antiparticle to matter, wherein if a particle and its antiparticle come into contact with each other, the two annihilate —that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc2. This gives rise to high-energy photons (gamma rays) or other particle–antiparticle pairs-.

According to some recent research in the field of astrophysics, antimatter are particles that have the opposite charge of the particle that it corresponds to. For example, the antimatter of protons are anti-electrons (some refer to it as prolectrons) while for electrons are protrons. Theoretically, this types of particles no matter how illogical it sounds NEED to exists in nature for the sole reason of maintaining the law of conservation of mass. The way antimatter preserves this very essential law because constantly --- according to Quantum physics --- new particles pop out everywhere. Because this phenomenon defies the law of mass conservation and HAVE to exists in nature for it to work properly, antimatter need to fill in the gap. When new particles constantly pop out and disappear (the life of a particles can extends from a billionth of a second to infinity), antiparticles "bond" with them to neutralizes tha charge. For example, let's say a particle that has a positive charge appears out of nowhere in space, the antiparticle (which is a negatively type charge of the positively charge particle) "bonds" with the positively charge particles for their charge to become zero (1 + -1 = 0).\n     The darkness in the sky are nothing but void. It is just a space where nothing exists except particles poping out of nowhere. Also, it is a common misconception that the darkness in space are called dark matter because of what the name implies. However, dark matter in plain astrophysics definition (shortened) are matter that had been the product of the "creation" of the world and all of its after affect. For now, theses matter cannot be seen by our eyes nor any telescope out there, but it can be seen through complex geometry and calculus.\n     Light is considered to be a particle that has both the characteristic of a wave and particle. We call these characteristic as wave particle. \n     Also, as a side note, it's true that time doesn't exists in reality, but it DOES exists in its own different dimension. If you want to know why, post a question.

Photons, gluons, gravitons and Z are neutral and elementary so they are their own anti-particles.\n\nThe W+ and W-, the weak force carriers, are charged and are anti-particles.  W+ and W- can annihilate each other.

Anti-matter particles are particles that have the opposite charge of normal matter.  For example, a proton is a positively charged particle, it's opposite, a positron has the same properties but with a negative charge.  When a proton and positron come in contact, tremendous amounts of energy are released and the particles destroy each other.  \n\nIt is hoped that anti-matter reactors will be available some day.  However, anti-matter particles are very unstable and scientists have had little success in stabilizing them for more than a few nanoseconds before they cease to exist.

Matter is anything that occupies space. Matter is not alive so therefore cannot die.

Positron.  Same mass as electron but +1e charge.  And it is never refered to as an "anti electron".  Its name is positron.  Thats just as silly as calling it "positive electron".

The new matter is the sixth known form of matter after solids, liquids, gases, plasma and a Bose-Einstein condensate, created only in 1995.\n\nThis sixth state of matter was first created on December 16, 2003 by physicist Deborah S. Jin and is called Fermionic Condensate.  \n\nIt is a fermionic condensate which is a cloud of cold potassium atoms forced into a state where they behave strangely.\n\nEditted:  Although Quarks are interesting, they are not referred to as the "Sixth state of matter".   :-)

The clue is in your question:  "We find."  How do you know what becomes of antiparticles we don't find?

When you talk of the possibilities of Matter and Anti-Matter...we already have them.\n\nProblem in lies that if you seperate matter and anti-matter and combine them to forn energy, you have to find a way to contain the energy (there is alot from a small cumbustion)  There is the problem.  So my thoughts are not yet ready for warp technology.

antimatter cant rely be used for anything,it is just a scientific oddity that is studied by smarter people.the two property's of antimatter i know of is that it has negative gravity(but it cant be used to mack things levitate)and that it will explode with a extrema force in some conditions.so the only possibly practical use would be bomb making but we don't have the necessary tech.
