Question:
What happens when antimatter and matter meet? Can antimatter-matter reactions be use as an energy source



Replies:
Matter and antimatter annihilate one another when they meet, which means that they produce a whole bunch of energy, usually as a pair of photons. However, antimatter is rather expensive to make, and it is very hard to keep around in any significant quantity, so it would not make a very practical energy storage option (and it could never be an actual SOURCE of energy because energy had to go into making it in the first place - unless we found somewhere in the universe where antimatter was actually plentiful).
