The Singularity

**The Singularity** was an event in Central City caused by the reopening of an unstable wormhole due to Eobard Thawne's future power source, resulting in a destructive black hole that was ultimately stopped by Firestorm's sacrifice with help from the Flash.

## History

 File:Eobard's future power source.png
In 2015, The Flash created a wormhole by colliding with the particle accelerator's electron to travel to the past through the Speed Force. Later, when the Reverse-Flash tried to use the same wormhole to travel back to his time, the Flash came and stopped him; the former was erased from the timeline after his ancestor Eddie Thawne's suicide. The wormhole the Flash created was unstable, and after a period of time, Caitlin and Ronnie successfully closed it. However, even after the wormhole was closed, Martin Stein stated that the wormhole reopened due to Eobard Thawne's future power source.

The wormhole increased in power and magnitude, and eventually became the Singularity. It was later transformed itself to provide as a connection to another universe which made Zoom travel to Earth-1 and opened 52 breaches in Central City. It was closed when Firestorm separated in the eye of the singularity.

## Trivia

* For a long time, there was a misconception that the Singularity appeared due to Eddie Thawne killing himself thus creating a paradox and erasing Thawne from existence. However, in later seasons, speedsters such as Savitar and Nora West-Allen were erased, but there are no signs of a singularity forming. This is most likely because a singularity does not result from a paradox, since the Speed Force has the ability to preserve the timeline by keeping the actions of the erased speedsters intact as time remnants. Instead, it is most likely due to Eobard Thawne's future power source, which reopened the wormhole which later on increased to the size of a singularity. Thawne mentions his power source as the "key" which could be referring to a fail-safe, just in case Team Flash decided to betray him and shut down the accelerator (which would also close the wormhole to the Speed Force).
