The ultimate perpetual motion machine that physicists don't want you to know about! This brilliant circular logic proposes solving two problems at once: dump tumors into black holes, which emit Hawking radiation, which causes more tumors, which we can then feed back into the black hole. Voilà—infinite energy! Sure, it violates several laws of physics, medical ethics, and probably common sense, but who needs those when you've got a tumor-powered universe? Stephen Hawking is simultaneously facepalming and laughing somewhere in the multiverse.
