Cosmic Treadmill

The machine that turns the impossible flow of time into a track you can run.

The Cosmic Treadmill is a device used by Barry Allen to travel through time. It first appeared in the story "The Man Who Broke the Time Barrier!" in The Flash #125 (1961), where Barry Allen uses it to break the time barrier, paralleling the achievement of breaking the sound barrier and exploring the potential of time travel influenced by Einstein's theories. Labs or the Flash Museum, nor does it mention the Speed Force as its power source.

Quick Facts

Reader's Guide

The Cosmic Treadmill operates on the principle that time can be traversed with sufficient velocity and energy, as demonstrated in "The Man Who Broke the Time Barrier!" from Showcase #4 (October 1956). It also does not mention limitations like temporal fatigue or fixed points in time. The machine is simply presented as a device that allows time travel by running at superhuman speed.

Frequently Asked Questions

How does the Cosmic Treadmill work?

It functions by channeling Speed Force energy to create an infinite resistance loop that mimics the movement through eras. This allows speedsters to physically run their way into different points in history or potential futures.

Who uses the Cosmic Treadmill?

Barry Allen is the primary user who frequently relies on this technology when he needs to alter past events or witness future timelines safely. Other Flashes and speedsters connected to the Speed Force can also operate it under specific conditions.
