This week marks the anniversary of the recovery of the remains of Challenger's crew on the bottom of the Atlantic Ocean. On March 10, 1986, the Navy and NASA announced that they had found a compartment that contained the remains of the ill-fated space shuttle's crew.
When I think about space disasters, I am reminded of the space battle between Earth and Trisolaris in Liu Cixin's fantastic sci-fi novel. Stay with me here. Liu Cixin's Dark Forest novel needs to be read. In the novel, humans make contact with a nearby alien civilization, who proceed to make plans to invade earth, wipe out its human population, and re-populate it with themselves. The first battle between Earth's space forces and the would-be invaders ends badly for Earth, as thousands of space warships are destroyed in a matter minutes by a Trisolaran probe. The novel brings up an uncomfortable theory that humans have been all-too-willing to neglect: what if the universe is a hostile, deadly place instead of a curious one? Nick Nielsen is asking important questions about humanity's place in the stars, and Caleb Scharf is doing wonderful work explaining how life in the universe is likely to confront us at this stage of our development.
