The usuall theory of time travel is that if it would have been invented in the future, we would have known about it already.
Well, i am gonna prove to you that it does exist and it's been under our nose all this time.
This is how it works -
Imagine that you have two test subjects. Lets call them person A and person B.
A and B live in the same appartment and both live a normal life. At 11 pm person A goes to bed and falls asleep instantly, while person B is having a hard time due to insomnia and is wide awake.
If person A fell asleep, then it will feel like an instant before he wakes up. The time is now 7 am.
Person B never fell asleep and were wide awake untill 7 am.
This means that person A is now approximately eight hours further in the future than person B. But person B will act like nothing have happened when he meets person A even tho there is now a time difference of eight hours between the two test subjects, this is due to dimensions.
When person A fell asleep he was "sent" to a diffrent dimension where the time is eight hours into the future compared to the dimension he fell asleep in. But ofcourse the body doesnt just disappear in the sleeping dimension, that mass of the body is what we call a "copy". This is a copy of the exact same person that was sent into the "future" or a diffrent dimension.
The copy will act out it's life in a autopilot way, the way the real person might have lived his life or not. This is happening due to the fact that not everyone will sleep and therfore it is needed to have a dimension that plays out in a matter that would be likely to happen.
Person B will as we know not see any diffrence between the copy and the body that was sent away. Person A will now continue as if nothing have happened with other people that in diffrent situations and sleep habits ended up in the same timeframe and dimension.
Person A might meet someone in there that is a copy who was sent even further and perhaps he meets a "real" body that is falling asleep while he aint. This stranger will be sent even further than person A and a copy will remain in the bed acting out the scripted life.
The dimensions are endless. If i go to sleep after writing this i will end up a few hours further than you who is reading, untill you go to sleep and depending on how long you rest.
Coma patients is the "best" way to travel. !WARNING! Putting yourself into coma to travel is very risky. To end the travelling your copy have to wake up, that is the #1 rule.
If your copy dies then so will you. However, if you succeed, then you can go far.
Now give me my Nobel prize! (This is the part where you should notice it wasnt a serious post incase u somehow didnt earlier. I was bored)
