What it is

An 8-minute explainer from The Imaginary Axis that tries to put numbers on DC's Flash, working through comic feats and the physics they would imply. It covers his speed relative to light, the Speed Force, and what such powers would mean in real life.

In The Flash: The Human Race (1998) [LINK] , the Cosmic Gamblers get the Flash to run in a race for the fastest being in existence, where losing means the destruction of planet Earth. The Flash counter bets with the Gamblers that he can run faster than they can teleport. The Flash then gathers more Speed Force than ever and makes a move in less than a Plank Instant (smallest unit of time), arriving at destination before instant transportation of the Gamblers is achieved. [LINK] Being faster than teleportation is certainly faster than Superman, as we've never seen Superman able to catch up with teleportation. This is all scaled by the end of this interesting video: In The Flash Rebirth #3 (20

I have a question that no amount of Google-Fu will help. Searching for the flash, computers and programming only yields results in the computing realm. Given the following image: [LINK] And a calculation that the Flash can move at 23,759,449,000,000,000,000,000,000,000,000,000,000,000,000 x C (the speed of light) according to the video below: Based on his raw speed, I believe that he can process information faster than the fastest computer ever could. I don't have calculations on how the Flash's speed correlates to clock speed, but it is hard to believe that he would need a computer. Would the Flash ever need a computer/program or find one useful and would he be able to tolerate how slow the

Flash moved from the ends of the universe to Earth in less than a plank time. [this video] - He beat cosmic beings that could teleport instantly anywhere. In a bet.
