How would it violate any laws?
The conservation laws state only that the "energy + matter" going in to the reaction be EQUAL to the "energy + matter" coming out of the reaction. Remember that neutrinos have a very insignificant mass, and electrons have just a little bit more mass...so to have a proton and antiproton annihilate each other can result in quite a number of neutrinos and a few electrons along side those gamma photons.

Sorry, should have been more specific. I mean conservation of charge, lepton and baryon numbers. It has to put out anti particles that will also annihilate to jive with conservation laws. Unless Im missing something...

Isn't that what a pion is? A quark-antiquark pair?

From wiki:
Quote:
Over 99.9% of the mass of neutral antimatter is accounted for by antiprotons and antineutrons. Their annihilation with protons and neutrons is a complicated process. A proton-antiproton pair can annihilate into a number of charged and neutral relativistic pions. Neutral pions, in turn, decay almost immediately into gamma rays; charged pions travel a few tens of meters and then decay further into muons and neutrinos. Finally, the muons decay into electrons and more neutrinos. Most of the energy (about 60%) is carried away by neutrinos, which have almost no interaction with matter and thus escape into outer space.

They must mean positrons and electrons (sometimes the distinction is glossed over). Because you start with zero charge and zero lepton number and end up with charge and non zero-lepton?
Well, Im satisfied now that conservation is intact.
Its interesting that most of the energy is carried away in neutrinos. Need to make the bomb out of straight positrons then.

Now thats what I call a scary nuclear bomb! One that goes off if its switched off 
The A-bomb dropped over Hiroshima was armed aboard the plane with barometric ignition during flight. If the plane had dropped below a certain altitude it would've gone off.
Nukes pwn antimatter where it comes to budget. One kiloton of BOOM
requires 20 grams of Lithium Deuteride or 55 grams of Uranium 235. The LiD costs about 50 bucks.

Hopefully they would design something a bit more fool proof than that, like with real magnets rather than electromagnets, or backup power sources, etc

It would probably be 'better' as a space based delivery system, either for ship to ship or ship to planet. That way it would be relativly isolated. Perhaps there are space faring civilizations waging war with them right now... or maybe not.
I wonder how far out we could detect some alien anti-matter warfare or experiments, and if it would be distinguishable from noise?

This has been incredibly interesting. I wish I could chime in but I know nothing of particle physics.

Not true.
It (little boy) was initiated by radar altimeter. Two of the four radar triggers had to agree before a detonation was initiated. The barometric system was a backup to ensure safety, and could not initiate the detonation (it could only prevent it). There was also a timer to ensure that a detonation could not happen until the bomb had fallen for at least 15 seconds.

suppose extra terrestrials DID come here seeking war, i wonder what level of weaponry they would have and whether or not it would shock them if we lobbed an antimatter missile up their asses?

Lo Dis me first post. Aside A scientist working on bringing the whole relativity thing into one mathematical formula happened to do so. Can't remember it but it was so clean and precise as well as beautiful (In a mathematician kinda way!) He reflected on it extensively. He realized it had "Two" Solutions and both were Right. After considerable deliberation, He conceived the theory of another universe BUT Exactly Opposite to ours in every way. So became the first thought possibility of ANTIMATTER. Most out of box. More later SCEK (Like Oil Sheik)

does anybody know what will happen if a proton is split in half?? of course we all know the regular atom being split but what about the smaller particles?? this technology is nutz! People say that the smallest particle known to man now is the atom.. but wtf about the protons and electrons??
