In 1994 Xodyx, a Silicon Valley start-up company, developed an e-mail server that could deliver messages up to 36 hours before they were sent. The temporal informational paradoxes the device created, however, caused the founding of the company to unhappen in 1993, thus precluding the invention of the device itself a year later. The disappearance of the Xodyx device from space-time briefly caused the NASDAQ stock index to sink to a negative number.
