Every evening, in the city archive, the attendant places new folders on the shelves. If too many arrive during the day, the shelves sag, and the next morning the archive responds to requests more slowly. A black hole's memory works in much the same way: it doesn't just store information, it physically feels its weight.

The early universe was an extremely hot and dense medium. In this medium, like bubbles of steam in boiling water, bubbles of a new state of space spontaneously emerged — regions where physical properties changed abruptly.

Traditionally a black hole was described by three parameters — mass, charge, and angular momentum.
