Science-fiction movies and TV shows often refer to antimatter propulsion
drives. This is not as far-fetched as it may seem. In a matter-antimatter
annihilation event, a particle and its antiparticle annihilate each other and
release all of their mass energy (such as in the reaction p+p→2γ, for
example). How many of these matter-antimatter annihilation events are
needed to get our kWh of energy? And what is the total mass of protons and
antiprotons required to do this?
Hint: The antiproton has the same mass as that of the proton,
938.3 MeV/c2 = 1.6726ï10-27 kg.
I'm not great with the whole concept of anti-matter, any help please? Such as equations to use and general concepts?
