A group of scientists from Columbia University recently published a paper detailing how humanity could power an off-Earth colony by tapping into one of the universe’s largest and most powerful resources: black holes. The big idea here is that a spinning black hole gives off a certain amount of energy. If we enveloped this energy field with an external gravity source (a big gravity gun?) we could force the singularity to generate negative energy. This negative energy would, theoretically, sort of switch places with some escaping positive energy, thus freeing it from the black hole’s hungry grasp and making it…
