this is just a little idea i had after a friend told me how quantum tangling works; if you tangle two quantum particles, then accelerate one near to or at the speed of light, slowed it down and made from each quantum particle a simplistic quantum computer, you could in theory talk to your someone in a different time zone
right?
with this you could prove many time paradoxes and what not of time travel
guess all we need is a working quantum computer....
