This document summarizes a talk given by Jack Sarfatti on the topic of how the future may affect the past. Some of the key points discussed include:
1) Theories that attempt to unify general relativity and quantum mechanics suggest that time travel to the past may be possible through wormholes.
2) Quantum experiments have shown that measurements performed in the future can influence the present, raising questions about whether the universe has a predetermined destiny.
3) A post-quantum view incorporates the idea that future events contribute causal influences on present ones, with the past and future interacting at the present moment. This perspective suggests retrocausality, or the idea that the future affects the past.
