Antimatter is just the opposite of matter. If i was sitting in this room with the "antimatter me", he would look exactly the same, but if we were to touch there would be a extremely violent explosion. The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×10 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc²), or the rough equivalent of 43 megatons of TNT. (This is slightly less than the Tsar Bomb, the largest nuclear weapon ever detonated). Great fuel, but, The scarcity of antimatter means that it is not readily available to be used as fuel, although it could be used in antimatter catalyzed nuclear pulse propulsion for space applications.
You come into contact with antimatter more than you think. A banana actually emits antimatter, but the amounts are minimal. Its also vary costly. Scientists claim antimatter is the costliest material to make. In 2006, Gerald Smith estimated $250 million could produce 10 milligrams of positrons (equivalent to $25 billion per gram); and in 1999 NASA gave a figure of $62.5 trillion per gram of antihydrogen.
