The Particle Accelerator Explosion was a catastrophic event that devastated Central City. When the particle accelerator exploded the electron volt number climbed so high that they became unmeasureable. The energy from the detonation was suddenly thrown into the sky, fueling a dangerous storm cloud of dark matter. A wave of energy swept through Central City severely injuring and killing multiple people. Others were effected based on the substances they were standing by at the time, causing them to have abilities mostly related to their jobs. Some of these people, nicknamed meta-humans, have abilities like superspeed (see the Flash), some can turn into gas, some can blind others with light and etcetera. The particle accelerator was created by S.T.A.R. Labs, under the direction of Harrison Wells. This marked the beginning of heroes and supervillains infesting Central City, as well as the birth of The Flash.
