When a mass is moving at high enough velocities, time slows down.
Why is only forward slowing motion allowed through spacetime?
I'm no mathematician but I thought Newton's & Einstein's equations were time reversible as a consequence of t^2
Wave functions in quantum mechanics evolve in a reversible deterministic manner unless a measurement alters the behavior irreversible.
So if your spaceship had a invisibility cloak, no measuring devices, you wore a blindfold and somehow mastered a conscious telepathic connection to pilot the ship, could you travel the backwards arrow in time?
If so would this only be measurable by a clock or would our pilot also actually age faster?
