If we were to surround a rotating black hole with a mirror and shoot a laser beam inside it, the beam would get exponentially more and more powerful by stealing energy from the hole via superradiant scattering. It could eventually overpower the mirror and result in a powerful explosion on par with a supernova. We could prevent these black hole bombs from going off by harvesting some of this energy. Using this type of energy we can theoretically power civilization for millions if not billions of years. In fact, these black hole civilizations may be the last home for any species in a dying universe.

In 1996, the Argentine branch of Coca Cola announced they would give away free tickets to a Ramones concert in exchange for ten bottle caps. Massively underestimating the band’s appeal in Argentina, Coca-Cola didn’t have enough tickets available, resulting in riots and looting.

In 1877, a 35-year-old attorney from Montana named George Cowan was shot 3 times in the head. He then crawled to make coffee at an old camp, crawled through Yellowstone, crossed a river, got burned in a forest fire, had surgery to remove bullets, got thrown from a carriage before it rolled over a cliff, and while receiving care afterwards, his bed broke.
