Assuming all matter in the universe was created from the singularity known as the Big Bang, would it be theoretically possible to undo cosmological evolution and, in so doing, return the universe to a Hartle-Hawking state? To achieve this, one would need the following:
1. A force that exerts itself both offensively and defensively (a "Myles-Jack").
2. An opposing force that also exerts itself offensively and defensively (a "Shaq-Thompson").
3. A contained space in which the Myles-Jack and the Shaq-Thompson will collide (for our purposes, the UCLA-Washington game on November 8, 2014).
According to our models, the Myles-Jack would tackle the Shaq-Thompson, which would then tackle the Myles-Jack, which would respond by tackling the Shaq-Thompson, yielding yet another tackling of the Myles-Jack, setting off a perpetual chain reaction in which a running back is constantly being hit by a linebacker who is also a running back being hit by a linebacker.
The result, as seen in this simulated environment:
