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?

At least, this time, the Earth is safe, right? Not so much.

For more than half a century, physicists and astronomers engaged in heated dispute over the possibility of black holes in the universe. The weirdly alien notion of a space-time abyss from which nothing escapes - not even light - seemed to confound all logic. This engrossing audiobook tells the story of the fierce black hole debates and the contributions of Einstein, Hawking, and other leading thinkers who completely altered our view of the universe.

The Cygnus-Orion Galactic Arm Spur is engulfed in warfare. A four way brawl with its roots a hundred million years prior, with the Lanaktallan Unified Council on one side, a strange invader from a dying universe on another, the Precursor Autonomous War Machines, strengthened by alliances, coming back into the fight, and, of course, the Terran Confederacy of Aligned Systems.
