Sounds like him (or whoever he saw it off) is posting the plot of Travelers.My son has an interesting theory
( not sure where he got it from some bizarre tic -tic or whatever thing he stares at incessantly , he claims it's his own )
Anyway goes like this :
More along the lines of teleportation than time travel ( same thing I guess ) but is focussed on copying the consciousness ( soul) and implanting that into a new physical body in a different time
It sounds feasible given how far technology has come in mapping /copying the brain but copying and then resurrecting the soul is hard to get your head around
Like the articles in the links below
Good luck young people !
Let me know when you've nailed it so I can go back and make the Dockers not So sh*t
