how would you contain antimatter?

i used to work at a particle physics research lab.  our everyday operation was to take matter and antimatter and smash them together at extremely high energies; to do this required storing some antimatter.  \n\nwe did this using a specialized type of particle accelerator called a "storage ring" which is essentially a big circular tube, under vacuum, with a bunch of magnets to guide the positrons (the antimatter counterpart to electrons) around the circular ring.  as they went around at the speed of light, they'd lose some energy so we'd have to re-accelerate them at every turn.  but that's essentially it.  here's some pages to learn more about storage rings:\n\nhttp://www.lns.cornell.edu/public/lab-info/ring.html\nhttp://www2.slac.stanford.edu/vvc/experiments/bfactory.html\n\nat any given time we stored about 10^13 positrons, which is actually a considerable amount.\n\nif you don't need to keep them at high energy, you can use a form of magnetic confinement, which basically works on the same principle as the storage ring.  often this is called a "magnetic bottle" or by its real name, the "penning trap":\n\nhttp://www.physik.uni-mainz.de/werth/g_fak/penning.htm\nhttp://www.aip.org/png/html/penning.htm\n\ncheers!

The most obvious reason is that you need a huge load of energy to create anti-matter in the first place. Anti-matter does not exist in a stable condition anywhere close and we have to create it. We can't just harvest it from the environment. It's also true that storing it is a major pain in the a$$.\n\nFusion is a much more realistic possibility. Try searching the internet for ITER (the first fusion reactor to be built in France by an international collaboration, currently under design).

The gravitational interaction of antimatter with matter or antimatter has not been conclusively observed by physicists. While the overwhelming consensus amongst physicists is that antimatter will attract both matter and antimatter at the same rate matter attracts matter, there is a strong desire to confirm this experimentally. If the gravitational interactions between antimatter and matter were found to be repulsive it would be a potential violation of conservation of energy – arguably the most fundamental law of physics.

Basically, it has to do with opposites. Every particle of matter has an opposite particle of antimatter. When these two come in contact, they annihilate eachother.\n\nIf every particle of matter were to find it's specific particle of antimatter, the universe would cease to exist. Theoretically.

oh, wow, this is a physics question.\n\nto start, we remember E = mc^2\nthe problem gives 4 grams matter and 2 grams antimatter.\nmy solution would be that 2 grams of matter and 2 grams of antimatter annihilate to produce 4c^2 (2 + 2 = 4) energy.\nthe excess 2 grams of matter remains unaffected.\nthe answer is D.

Personally I think the reason that there is less antimatter than matter has something to do with the arrow of time.  The last time I checked there was still not a very good explaination of why there is more matter than antimatter.  Its still an outstanding problem in physics.  Its a subject that, as a physicist, I'm very interested in.  Who knows, maybe you'll come up with an explaination.

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.

At present antimatter is generated in scientific factories in very very small quantities for experiements with the use of particle accelerators or decelerators.

If it were posible for the neutronium to exist in a plane, then yes, I think so. However, neutronium is so dense that its own gravity will pull it into a sphere. If you got close enough to look at it, it would pull you in and you would be a (very thin) stain on the surface.\n\nNeutron stars are supposed to be made mostly of neutronium. If two collided or got close enough for their tides to pull one apart, then small pieces might be left. But neutronium is supposed to be very unstable. It is only its own gravity that binds the electrons and protons together so that they merge and lose their identities. \n\nFor very massive neutron stars (just short of being black holes, I guess) their inner layers are supposedly a quark-gluon soup. \n\nFor very small ones or pieces broken off, if that is possible, if there is not enough gravity to keep the particles together, the electrons and protons will regain their identities and the nuclear interctive forces will reassert themselves, and the mesons will begin to interact between the electrons and protons again,. What would happen is that the small piece of neutronium would erupt in a burst of energy and high energy particles. \n\nS/F writers like H. Beam Piper (in the 60's) postulated that we would learn to control nuclear forces like we learned to control electricity and have (what he called ) 'collapsium' plated spacecraft, where the outer shells of the electrons were in contact with the nuclei (what we would now call 'degenerate matter'.) Such a plating (a tiny fraction of an inch thick) would protect like several feet of lead shielding. It would also weigh more than many feet of lead shielding! (He also proposed that we would have antigravity by now.)\n\nTheoretically, a sphere of neutronium would be perfectly reflective, and the noted s/f author Larry Niven used that feature in his classic story There Is A Tide (1968, Galaxy magazine.)\n\n15 NOV 06, 1632 hrs, GMT.

Antimatter or contra-terrene matter is matter that is composed of the antiparticles of those that constitute normal matter. If a particle and its antiparticle come in contact with each other, the two annihilate and produce a burst of energy, which results in the production of other particles and antiparticles or electromagnetic radiation. In these reactions, rest mass is not conserved, although (as in any other reaction) energy (E=mc²) is conserved.\n\nScientists in 1995 succeeded in producing antiatoms of hydrogen, and also antideuteron nuclei, made out of an antiproton and an antineutron, but no antiatom more complex than antideuterium has been created yet. In principle, antiatoms of any element could be built from readily available sources of antiparticles. Such antiatoms would have exactly the same properties as their normal-matter counterparts. The production of antielements in bulk quantities seems unlikely to ever become achievable, however.\n\nPositrons and antiprotons can individually be stored in a device called a Penning trap, which uses a combination of magnetic field and electric fields to hold charged particles in a vacuum. Two international collaborations, ATRAP and ATHENA, used these devices to store thousands of slowly moving antihydrogen atoms in 2002. It is the goal of these collaborations to probe the energy level structure of antihydrogen to compare it with that of hydrogen as a test of the CPT theorem. One way to do this is to confine the antiatoms in an inhomogenous magnetic field (one cannot use electric fields since the antiatoms are neutral) and interrogate them with lasers. If the anti-atoms have too much kinetic energy they will be able to escape the magnetic trap, and it is therefore essential that the anti-atoms be produced with as little energy as possible. This is the key difference between the antihydrogen that ATRAP and ATHENA produced, which was made at very low temperatures, and the antihydrogen produced in 1995 which was moving at a speed close to the speed of light.\n\nAntimatter/matter reactions have practical applications in medical imaging, such as positron emission tomography (PET). In some kinds of beta decay, a nuclide loses surplus positive charge by emitting a positron (in the same event, a proton becomes a neutron, and neutrinos are also given off). Nuclides with surplus positive charge are easily made in a cyclotron and are widely generated for medical use.\n\nAntiparticles are created everywhere in the universe where high-energy particle collisions take place, such as in the center of our galaxy, but none has been detected that is residual from the Big Bang, as most normal matter is.[1] The unequal distribution between matter and antimatter in the universe has long been a mystery. The solution likely lies in the violation of CP-symmetry by the laws of nature; see baryogenesis.\n\nhow much produced it is on and on and on

Yes and No, Since a black hole is made of particles, anti-matter could counter and destroy it, on the other hand, most believe it is an actual hole in the fabric of space/time. So can you repair it, not as of yet. 2nd an A-bomb is nothing to a black hole, so it wouldn't do much. 3rd, I've never heard of plasma being able to escape a black hole, theoretical energy, thermal energy, and certain virtual particles are the only thing I know that have been thought that could escape a black hole. 4th, Black holes can merge into 1 really big one, so they continue to live even through themselves.

In 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. The resulting particles are endowed with an amount of kinetic energy equal to the difference between the rest mass of the products of the annihilation and the rest mass of the original particle-antiparticle pair, which is often quite large.\n\nAntimatter is not found naturally on Earth, except very briefly and in vanishingly small quantities (as the result of radioactive decay or cosmic rays). This is because antimatter which comes to exist on Earth outside the confines of a suitably equipped physics laboratory would inevitably come into contact with the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in minuscule amounts, but not in enough quantity to do more than test a few of its theoretical properties.\n\nThere is considerable speculation both in science and science fiction as to why the observable universe is apparently almost entirely matter, whether other places are almost entirely antimatter instead, and what might be possible if antimatter could be harnessed, but at this time the apparent asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics. Possible processes by which it came about are explored in more detail under baryogenesis.

I assume you mean the whole facts about the anti-matter.  Well CERN does exist and people are trying to create anti-matter. We have produced elementary particles with particle accelerators but I'm not sure about anti-matter.  I would assume it could be held in place with a strong magnetic field though to stop it annihilating, however I seriously doubt they'd have containers which could be transported elsewhere with batteries that run down, that would be a rather stupid idea really.

The anti matter is actually very unstable. It all got anhilited after reacting with the matter particles. The probability of an antiparticle  encountering a matter particle is very high because the matter is much much more compared to the antimatter, so probably most of the anti matter has already been 'burnt'.

Antimatter is as real as matter itself, just ask particle physicists\n\nThe reason we do not have much of it around us is that it annihilates with matter, so our world now is matter dominant.

No, neither. When matter and anti-matter get together you get a lot of gamma rays, and assorted other known particles. This has been observed many times in the larger particle accelerators. Nobody knows what dark matter or dark energy are made of, but we do know they aren't made of the things we've detected in our accelerators yet.

the spontaneous creation and destruction of particles goes on all around us all the time.  but antimatter does not seem to be part of that process in our "timeframe" and it could be that if time is viewed as a dimension only we will find the antimatter at another point on that dimension.  If antimatter did appear annihilation would occur on a vast scale.  I believe that matter and antimatter have a weak repulsing force to each other, or utterly neutral, as the antimatter has a "reverse gravity" (perhaps because it's moving backwards on the time dimension).\n\nOur Universe, all the parts that count to us, is all matter.  The antimatter resides next to us, but not in our universe.
