Antimatter,
A positron is an electron but with oposed charge and if it colides with an electron it eill anihilate and become energy. But why does it anihilate? Would it anihilate if it colides with a quark or a muon?

@Andeolus whyu they anhilate?..ok very simple layman answer(note:this answer isn't upto the rigor required by QM) $$=+1 -1 = 0$$ And one more thing the product of annihilation isn't predicatble(But it mostly produces photons) links(read them out..they are great..I'll message you more[Searching my bookmarks)): http://www.quora.com/Can-a-muon-annihilate-with-a-positron http://www.quora.com/What-specifically-happens-when-a-proton-and-an-antiproton-collide http://www.quora.com/Quantum-Mechanics/How-can-a-photon-with-zero-mass-split-into-an-electron-and-positron-which-do-have-mass-even-temporarily-Assuming-they-annihilate-each-other-very-quickly http://www.quora.com/Why-cant-an-electron-absorb-a-part-of-a-photon http://en.wikipedia.org/wiki/Electron%E2%80%93positron_annihilation
