First, a quote
<!--quoteo--><div class='quotetop'>QUOTE</div><div class='quotemain'><!--quotec-->"Best science moment?"
"When I learned that NASA and a few other organizations actually store anti-matter. Anti-matter is currently the most expensive substance in the world.

I used to think storing anti-matter was impossible simply because it would annihilate instantly with anything it came into contact with. Apparently the trick is to store it in a vacuum chamber and keep it from annihilating with the walls of the chamber by using a magnetic field to create a 'magnetic bottle.'"<!--QuoteEnd--></div><!--QuoteEEnd-->
Then, a site of videos. Go hydrogen!

    I was under the impression that antimatter had not yet been created and contained in a stable form.

    I think the quote is from "Angels and Demons" or whatever that prequel to "The Da Vinci Code" was. Don't really see how it's related to the admittedly cool videos underneath though.

    Wikipedia (naturally) has a pretty good page on antimatter. Some select facts:

    <!--quoteo--><div class='quotetop'>QUOTE</div><div class='quotemain'><!--quotec-->The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc²), or the rough equivalent of 47 megatons of TNT. For comparison, Tsar Bomba, the largest nuclear weapon ever detonated, reacted an estimated yield of 50 Megatons, which required the use of hundreds of kilograms of fissile material (Uranium/Plutonium).<!--QuoteEnd--></div><!--QuoteEEnd-->

    Er, actually it's just some ordinary guy on a nerdsite I frequent who said it...

    I thought it would be more dangerous than even that.

    Well, when you consider the long term ramifications of such a large release of gamma rays it might be.

    That's the exact premise of Angels and Demons. Maybe they actually did start doing that, but when you think about it, what's the purpose of storing antimatter, especially when it would take so much energy to have that strong of a magnetic field.

    For the same purpose as creating a battery. If the energy used to produce and contain anti-matter can be lowered to something less than the energy (or value of energy) created when it's used in a specific circumstance, then it's worth it.

    For example, it may cost more to store energy in a battery than to just send it directly to a light bulb; however, the means to produce this electricity are not present in the bottom of a mine shaft, so it's worth it to waste some energy to make those batteries and use them in remote locations.

    Antimatter would never be good for a battery for the same reason flywheels will never be good: catastrophic failures.

    And while I can believe we can use electromagnetic fields to contain antimatter(see the late great Bussard's Fusion Project) I don't believe we're near the level of antimatter storage at all(see the late great Bussard's Fusion Project)

    The purpose of storing antimatter is to prove we can. I don't see why I need to explain this. The first steps in ANY new field are pointless by themselves, but often lead to something greater. The method of storage, in this case, is a method of containment that allows us to prevent antimatter from immediately contacting matter and annihilating itself. The next step could be moving the antimatter in highly controlled ways. Then moving streams of matter AND antimatter in highly controlled ways. Then mixing them under precisely controlled circumstances. Et cetera, et cetera.

    Weapon technologies, just like most huge government projects
  • lolfighterlolfighter Snark, Dire Join Date: 2003-04-20 Member: 15693Members
    I wonder what kind of weapon you COULD make with antimatter, actually. The most obvious one would be a bomb, but an antimatter bomb would be horrendously dangerous to store. Fission bombs are typically designed to fail safe - an error will cause the weapon to not detonate properly, if at all. An antimatter bomb could only fail deadly.

    Antimatter is the single most dense form of energy storage humans are currently capable of, and will foreseeably BE capable of given what we currently know of physics.

    That 47 megatonne number for 1 KG of antimatter seems a bit low, not sure though. I came to 2 megatonnes when I did the calculation myself, can't work out what I did wrong.
