It is not surprising that some of the best visions of technological resurrection have been proposed by science fiction writers. What is science fiction, after all, but the best way to talk meaningfully of wild speculative, still mysterious science and technology, and their likely impact on our world?
The Light of Other Days is one of my favorite science fiction books ever. It was written in 2000 by Stephen Baxter based on a synopsis by Arthur C. Clarke. This breathtaking and well written story features awesome, “magic” science and technology, from a communication breakthrough based on the exotic physics of quantum wormholes all the way to mind fusion, group minds, past viewing, and the resurrection of the dead. Very, very highly recommended.
Quantum entanglement is a “weird” conduit between events in spacetime, not limited by the speed of light. Wormholes are also a “weird” conduit between events in spacetime, not limited by the speed of light. New research seems to imply that perhaps these two weird things are really one and the same.
