The Light of Other Days

'''Baxter, Stephen, and Arthur C. Clarke. The Light of Other Days.''' New York: Tor, 2000.

Wormhole technology is used to send digitalized data by electromagnetic radiation eventually including visible light. A logical development from the laws of space-time allows light waves to be detected from the past. This enhances the wormhole technology into a "time viewer" where anyone opening a wormhole can view people and events from any point throughout time and space.

When the technology is released to the general public, it effectively destroys all secrecy and privacy. [...] Anyone is able to observe the true past events of their families and their heroes.

An underground resistance to this surveillance and to the revelation of the true history of religions (etc.) "utilises a direct neural interface coupled with the unlimited communication provided by the wormhole technology to develop a group mind."
