Anti matter bomb

Anti matter bomb‏‎

An antimatter weapon is a device using antimatter as a power source, a propellant, or an explosive for a weapon..

The primary  advantage of such a weapon is that antimatter and matter collisions convert and produce a greater fraction of the weapon's mass into explosive energy when compared to a hydrogen fusion reaction, which is only on the order of 0.4%. The basic equation governing the antimatter reaction is Einstein's famous E = mc^2, but, since a given mass of antimatter needs an equal mass of ordinary matter with which to react, this effectively becomes E = 2mc^2. Therefore a gram of antimatter would need a gram of ordinary matter to release its energy and the energy developed would be 2 * 1e^-3 * (3e8)^2 = 1.8e^14 joules. Using the convention that 1 kiloton TNT equivalent = 4.184e^12 joules, the gram of antimatter reacting with its ordinary matter counterpart gives 43 kilotons of explosive force.
