Speed Force

The Speed Force created by The present (God of DC) is a fictional cosmic energy field and force based around velocity and movement, and one of the Seven Forces of the Universe. The Speed Force in DC Comics is an omnipresent, extradimensional energy source that acts as the kinetic engine of the multiverse, existing everywhere, across all time and space. It appears in publications by DC Comics, mostly in Flash stories. It is the representation of reality in motion, being the very cosmic force that pushes space and time forward. The Speed Force exist outside time and space in the 5th dimension. It grants all speedsters their power. Several speedsters have merged with it, including Barry Allen, Johnny Quick, and Max Mercury. Eobard Thawne stated that at its core, the Speed Force is equivalent to time itself, describing it as existence moving through reality, kinetic energy, and temporal energy.

It first appeared in The Flash (vol. 2) #91 (June 1994), and was created by Mark Waid.
