The Halley's Comet Panic

The 1910 return of Halley’s comet was greeted with rapture around the world—at least at first. Due to irresponsible speculation by scientists about the theoretical dangers of a close encounter with a comet, many people grew terrified of Halley’s approach and took drastic measures. They fled their homes, hid out in wells or caves, even committed suicide. It’s a grave reminder of scientific communication gone very wrong.
