Antimatter explosion

An antimatter explosion can be caused by a breach of a matter/antimatter reactor, or antimatter pod. This loss of containment results in an interaction with matter that annihilates both substances and converts them into large quantities of energy in a short amount of time.

Antimatter explosions are a serious hazard for vessels powered by matter/antimatter reactors.

In 2258, the USS Enterprise (alternate reality) was being sucked into a black hole. chose to eject the ship's warp cores into the singularity, causing a massive antimatter explosion that safely swept the ship away.
