Ok, so given that an electron and an anti-electron* will annihilate each other, resulting in a burst of energy, and that a proton and an anti-proton will annihilate each other, resulting in a (presumably bigger) burst of energy.... what happens if an anti-electron encounters a proton? There's something like an 1840x difference in masses, so they can't just annihilate each other, right? And if the anti-electron only combines with 1/1840th of a proton, what happens to the rest? We've got to be talking partially destroying a quark, right? Any partical physicists wanna help me understand what happens?
* OK, fine, positron. Damn geeks.
