    Im trying to understand antiparticle and I appreciate any input I could receive.
    Antimatter/antiparticles of all the electrons that existed in every one of my cells will be produced from remains of my body thru decaying?
    If so, CP symmetry in this universe is maintained with time delay?
    I apologise in advance for my questions being silly to many - I dont have my background in physics.

    I don't know what mode of burial is usual in your country, but where I come from the bodies of our dead tend to decompose into something less exotic than antimatter.

    If you intend to posthumously transform into antimatter please don't get buried anywhere within a 500km radius from my home.

    Thank you for your consideration.

    I was merely questioning about possible application of the concept of antiparticles to biological macromolecules as for example human body consists of billions of electrons and the antiparticle of the electron is the positively charged antielectron/positron produced naturally in certain types of radioactive decay.

    I do not have the slightest interests to consider where a geological 500km radius is from your home.

    Thank you for your understanding.

    Seriously now, creation of antimatter is a physical phenomenon on a completely different level from the biochemistry of body decomposition. It's as different as the rotting of paper is different from the parsing of sentences written on it.

    Likewise, radioactive "decay" (nuclear fission) is entirely different from the "decay" (rotting) of a dead body. Our bodies do contain some radioactive isotopes (such as ), but their fission, which does create tiny amounts of antimatter, does not depend on whether we are alive or dead, embalmed, frozen, or decomposing.

    If all the electrons in a, say, 80kg human body were somehow suddenly transformed into positrons, they would attract the corresponding number of ordinary electrons from the surrounding matter (clothing, coffin, soil, air....), and the resulting explosion would be equivalent to roughly half a megaton of TNT.

    LOL!

    Ever heard of spin angular momentum? Or chirality? See http://www.springerlink.com/content/8877061410715w27/ for a mention of positrons and chirality. And have you ever heard of topological quantum field theory? That's related to knots. And knots can be chiral. Think of matter and antimatter as being similar like two shoelace knots are similar when you tie one right-over-left and the other one left-over right. You will not find that one of these knots spontaneously transforms into the other.
