What I’ve learned from reading Physics of the Future by Michio Kaku:
There is a theory of a form of energy that is really, really powerful called planck energy. I’m sure I will be totally getting this concept wrong because I just looked it up on Wikipedia and understood none of the descriptions. But from what I understood from my reading, planck energy is equivalent of 10 to the 19th power billion electron volts, which is powerful enough to rip time/space and make things like black holes and worm holes and time traveling and stuff.
It sounds fun to me. And dangerous. And it would make a good story.
