Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.
