    What do you mean "if it is true"? Antimatter is used all the time. The P in a PET scan stands for positron which is the antimatter equivalent of an electron. Positrons are also used in particle accelerators.

    I'm not sure, but I think I remember reading about them creating anti-hydrogen (a positron with an anti-proton) in the lab.

    And no, not everything has an antithing somewhere. There was no Anti-Harbourboy somehow created by his anti-parents at the same time Harbourboy was created by his parents.

    Uh, no, I'm sure it doesn't.

    We can make antiparticles in small quantities and even simple antimatter, so it should be possible, in theory, to create an antianything sometime in the distant future. An AntiChevalier (certainly a chaotic evil, fallen paladin) would blow up, in spectacular fashion, when he came in contact with Chevalier or anything made of ordinary matter.

    What doesn't make sense is the abundance of matter and the apparent dearth of antimatter in the universe. As far as I know, nobody can explain why there is such a discrepency.

    I wonder if an AntiParisHilton would release a celibacy tape.

    They are apparantly going to use anti-matter to help remove cancer tumors. The principal is sound, but you need a lot of them (it took several months and a lot of money to make 3 positrons in a lab)

    Eh? Positrons are "created" naturally through beta decay of certain radioactive isotopes, and those isotopes are readily created in cyclotrons. If positrons were so difficult to make as you describe, PET scans would be far too expensive.

    Maby I'm wrong then, but how much do they use in PET scans?

    I dont' know exactly, but it's a scan so it has to be a significant amount. Regardless, there're all kinds of people getting PET scans all the time, so it can't be that expensive.

    EDIT - Oh, and it's the radioactive isotope that's manufactured for the PET scans because they want the positrons inside the body where they will annihilate with electrons and emit gamma rays that can be detected during the scan.

    Maybe you meant anti-protons; they're much more massive and thus more difficult to "create".

    What about dark matter? What effect would it cause if this theoretical matter came into touch with either matter or anti-matter?

    IIRC, dark matter particles are passing through everything constantly. It has no effect on anything, apart for compensating for some problems in scientists' equations.

    "What doesn't make sense is the abundance of matter and the apparent dearth of antimatter in the universe. As far as I know, nobody can explain why there is such a discrepency"

    As far as I know, the whole thing is the natural stat called "SPIN" of the particle.
    Any anti-matter particle will "rotate" in an oppositte direction than a matter particle.
    The spin of a matter particle is (in a universe of matter) stable, while an anti-matter particle is not.(I suppose this also will work reverse ways in an opposite universe of anti matter)
    May be that explains why they are so difficult to create an handle them.

    "I wonder if an AntiParisHilton would release a celibacy tape."

    That wouldn´t be fun to watch,at least in this universe of matter.

    BTA@: Anti-protons! that was it. Thanks.

    I was under the impression that Dark Matter was a collective term for matter that scientests have no way of identifing.

    Can someone answer this question for me:
    Is there such a thing as an anti-neutron?

    I only ask because it seems obvious there should be, but is sounds stupid. What charge do they have?

    Magister, an anti-neutron is just made up of anti-quarks instead of quarks. I believe it's the same organization of quarks, two down and one up, though two anti-down quarks and one anti-up quark. Or something like that... it's been a while since I've had to take any classes on quatum physics or chemistry.
