How do you manufacture antimatter?

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.

Antimatter is real and has been created in the laboratory.\n\nTo be honest I don't really know exactly WHAT it is (I never got that far in Physics, that's pretty advanced stuff), I just have a sort of general concept of it.  It has mass just like regular matter, but is not the same -- the two completely annihilate each other if they come into contact.  I imagine it is just a rare type of matter put together in such a way that when it contacts "normal" matter all the whatever-it-is that they are made of cancels out.  But matter can't just cease to exist, it must be converted into something so that something is energy, like in a nuclear reaction when some of the matter of the atomic nuclei are converted into high-energy radiation.

You could make a cloud chamber. It's a chamber that's saturated with alcohol vapor so when a cosmic ray or radioactive particle enters the chamber it leaves a trail of mist like when a plane leaves a vapor trail. It does use dry ice and isopropyl alcohol though. It's kind of complicated but would be worth it in the end.

It has a 2 microsecond half life, so it is not abundant anywhere. You can hardly keep it in a jar.\n\nIt is made at supercolliders, such as CERN.

nothing what's the antimatter with you! seriously though if you mean antimatter, it's a form of matter in which most of it's properties are reversed.

You can't. Alchemy is a myth. Without nuclear reactions, you can't turn lead into gold, or any element into any other element.

anti-matter happens to have an opposite charge of matter, like a proton with a negative charge would be anti-matter here.  If matter and anti-matter happened to be in the same space they would cancel eachother out and the only thing left of them would be I think it was either Beta or Gamma rays, mabey Infered.  \n\nDark matter, is something else.  It's a contraversial subject and scientists LOVE to debate about it, I don't know ANYTHING about it, but you could look it up.

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.

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

Anti matter is negative version of matter.To differentiate the matter and antimatter we consider the atomic levels of matter.Our own matter is made with atom of centraly proton of positive charge & charge less neutron called nucleus.And a negative charged electrons revolving around it.But in antimatter nucleus is  negative charged proton(anti proton)& electron of positive charge (anti electron) revolving around it.\nI think that matter and antimatter repell each other,have a negative gravitation.

Electron-positron annihilation is the process that occurs when an electron (which is matter) and a positron (which is antimatter) collide. If they are both relatively at rest (which happens in an exotic but not uncommon form of matter called positronium), they destroy each other upon contact, and produce two gamma ray photons of 511 keV each which are emitted in opposite directions. If they are moving at different relative velocities, the energies of the photons emitted will be higher, in accordance with the conservation of momentum. [At higher relative velocities, other particle-antiparticle pairs can also be produced, since there is enough kinetic energy in the relative velocities to provide for the masses of those particles. At much higher relative velocities, there may be enough energy to produce a single neutral Z-boson. The opposite process is known as pair production or matter creation.]\n\nOf course, both the electron and the positron cease to exist, as their masses are converted to energy (E = mc^2), which is the energy of the two resultant photons.\n\nThere is no separate law of conservation of matter (or, mass). Actually, it goes together with the law of conservation of energy, under the name 'mass-energy conservation'. And this conservation of mass-energy, as well as the conservation of momentum, both hold during the process of annihiltion.

One should not group antimatter particles all into the word element. It is possible to make any of the elements in the form of antimatter, and for any element the antimatter equivalent would be incredibly rare here on earth. Now to say the rarest is very hard because there could be at any given point in time a number of antimatter hydrogen atoms that might seem like a large number, to the human mind, here on earth. Anti hydrogen would be the most abundant anti element, although still inconcievably rare. However, some of the heaviest non-antimatter elements that have been created in the lab probably ocasionally briefly come into existence in nature here on earth. Some of these metals might be rarer than antihydrogen, the most abundent antielement here on earth. \nNote: positrons, anti electrons, are the most abundent easily observable antiparticle, but I have left them out because they are not an element.\n\nNow, as for the universe in general: It is a real curiousity that there does not seem to be an equal amount of antimatter as matter. We humans do not now how to create matter without also creating an equal amount of antimatter. Yet, it seems as though our universe is made up almost entirely of matter... What happened to all of the antimatter during the creation of the Universe??? I don't know, and as far as I am aware of there is not a solid leading theory to explain this enigma, but many ideas have been suggested with associated mathematics. Some of them propose that the antimatter went into another dimension. Others propose that there was a very slight inequality in the quantity of matter and antimatter with the difference being the matter that is currently in existence. Still others contend that the some total of matter and antimater within the Universe are still of equal quantities, but the areas where this antimatter is hiding is too far for light to have reached us from those locations. Although I have a preference between these ideas, I will not say what it is. So, lets just say that that might be a good topic for someone interested in the subject to do some real research.

Imagine an atom where the protons have a negative charge, and the electrons have a positive charge.  That's antimatter.  Minute quantities have been created in the laboratory, but it has to be stored in a magnetic bottle, since any contact with normal matter causes the antimatter and an equal quantity of matter, to be converted to energy.

put the counter closer cos alpha raysonly travel a short distance...maybe that will work?... \n\nor get something that will alter with radiation... i think there a material that changes colour when hit with radiation....\n\nOOOOOOOOOrr... get something that emits a longer range radiation ray when the alpha partiles hit it...that way u can get a good approx of the count

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).

If you are doing it in a laboratory setting, you can mix it with carbon and reduce it to the metal. You will need high temperatures, though.

if you had a bunch of antimatter - anti-protons, electrons, and neutrons, they would annhilate with the water, destroying both but producing a whole bunch of energy
