There is a way to travel back in time already, I figured it out in deep thought yesterday. (It’s been outlawed by mankind though.) A person would simply need two massive space drones, some poles, and a camera. Basically, just attach the drones to the axis of the earth, halt it from spinning, then set to work spinning it backwards. Simple, easy. I think we already all know this.
The problem with this idea is that time is relative. It’s not that it doesn’t work–that we couldn’t go back in time, but it would be nearly impossible to set it straight to a direct time. Imagine setting an analog watch, no watch is exactly on time. Greenwich isn’t ever on time. Time is relative. SO how fast or slow we spin and where we end up is a gamble.
This time machine idea would impact the entire world, as it would alter the entire world. No one is ready for that change. We can’t even agree on politics. Stopping the world for someone in the prime of their life to go back to your prime would ultimately not be a good deal for the former. There is too much riding on it. End of discussion. Call it insane, impossible.
It’s already been done though, we have gone back in time. We have interpreted and created our dead ones again: look at museums. We are there. The technology is there. Two drones, some poles and a camera. Stop the world and spin it backwards. That is how we create what a time machine would create. How we change time. The camera is how we know what the past looks like. Don’t agree? Prove me wrong.
