Dark energy flare

A dark energy flare or dark energy cascade is a type of exponential reaction in which a stable singularity collapses, releasing a pulse of displacement energy.

Types
There are two kinds of dark energy flares: stable and destructive.

Stable dark energy flares
Stable dark energy flares occur when low-mass singularities collapse or when large singularities collapse slowly over an extended period of time. Dark energy reactors generate these types of pulses several times per millisecond.

Destructive dark energy flares
Destructive dark energy flares occur when singularities of multiple solar masses collapse completely over a small timeframe. Such flares release significant amounts of heat and kinetic energy equal to several megatons.

Only two destructive flares are known to have occurred: the blast at Nova Prospekt, and the blast that destroyed City 17.
