Wormholes. Travel some place faster than light and see light from the past from your source of travel when you arrive, travel again back to your original spot and theoretically you travel backwards in time to before the light from the past that you just saw was even produced yet. Might work the same for just seeing the future if you glimpse through a wormhole that leads to someplace in the future by doing an Allie oop to further into the future someplace far away, then back to someplace in your future but your destinations past. Speed and gravity both impact time. A wormhole fits that description to a T.
I love how people act like their knowledge alone somehow makes them better than their peers, just utilizing knowledge to appear aloof, or above it all, when in reality, if capitalism shot itself in the chest and socialism took over tomorrow, we would still have the same rich 1% families stealing from the working class and none of us would actually be in any better a position because no damned political system to date has figured out how to keep the rich from sacrificing the poor for their own selfish ends. End of story. Time to change.
