How to avoid a cosmic catastrophe

Imagine an advanced civilization somewhere in the universe, which has developed a particle accelerator that strikes electrons at the Planck Energy, the scale where gravity is to be described mechanically quantum. This energy scale is not an easy task for a collider, because it corresponds to ten quintillions (1019) times …
