Déjà Vu

People say that hindsight is 20/20 What if foresight could be 20/20? Quantum Theory suggests that where a person is in time determines WHEN that person is in time. The big bang, is ‘time zero’. Dinosaurs would still rule the earth at a point in space 650 million years behind our current location on our current trajectory. At a point that is located 1650 years behind us, on our current trajectory, the Romans would still dominate Europe. At a point that is a mere 80 years behind us, the outcome of World War Two would still hang in the balance. If a Tachyon wave slammed into the solar system, moving it backwards one year in space-time and slightly altering the direction our solar system was traveling in space. How would the humans living in that moment handle their opportunity to alter their own future? Would they take advantage that random chance and change their lives for the better, or would they simply ignore that opportunity and repeat the mistakes of the past.
