# Antimatter bomb

When a massive particle collides with its corresponding antiparticle, they annihilate, producing photons with energy equal to their rest mass energy.

Imagine that you had $$1\text{ g}$$ of hydrogen and $$1\text{ g}$$ of anti-hydrogen. How much energy would you release if you let them collide? Express your answer as an order of magnitude. (That is, $$k$$ where your answer is of the form $$a \times 10^k$$ Joules).

For comparison, the atomic bomb detonated over Nagasaki released $$8.8 \times 10^{13}\text{ J}$$.
