Today I read about a physicist that created a black hole in his laboratory in Israel. the black hole he created swallowed sounds, not light. It used rubidium atoms supercooled to barely above absolute zero, and accelerated them to a speed beyond what sound can travel through. This creates a sort of event horizon, a point-of-no-return past which sound cannot exist. I’m not sure how he technically did this– does he have the ninja mega vitamix to scramble photons.
