Antimatter: Hooh. Good God, y'all. What is it good for?

1 Answer

Answer :

Antimatter annihilates matter when the two meet, releasing energy in the form of gamma rays. This is the principle used in Positron Emission Tomography (PET) scanning. Antimatter is a promising form of fuel for space vehicles, since it releases huge amounts of energy while requiring little mass. A containment system would allow large amounts to be stored in preparation for a future space mission.
