[DC] Can someone explain the Speed Force in great detail?

I know the Flash and others speedsters can tap into a "speed force" to use their powers, but does it get more diluted the more speedsters there are? Is the power infinite? I want to know what are the rules and limitations surrounding it are and in the greatest detail you can muster.

The Speed Force is an extra-dimensional power source that somehow transcends the standard "four-force" model of the observable universe (gravity, electromagnetic, strong force, weak force).  Due to this unusual nature, it allows wielders (known colloquially as Speedsters) to distort the laws of physics in highly unusual ways.  Basic examples are the ability to phase through solid matter or to run beyond the speed of light, extreme examples involve linear time travel (both forward and backwards, allowing for the possibility of paradox) and dimensional bridging.  The Speed Force can be harnessed by certain individuals who have either a genetic predisposition or have experienced certain atypical experimental conditions, and it does appear there is a finite limit to how much Speed Force can be channeled at any given time, but the exact nature of this limit is debatable and seems to change depending on the Speedsters involved in the situation.  

Overall, the ability to warp core physical laws means that Speedsters have a dangerous and difficult to define advantage over all other metahumans, who, regardless of powers, are typically constrained by the standard laws of physics as we understand them.  The only other beings we know of that have this ability to distort reality are Celestial level beings about who very little is understood.
