interesting. the problem with time is its inacurate man made and messed with .
they dont know when time began or monsters roamed the earth they guess
they judge time on the sun and moon yet its sunny in england dark in china so thats foolish for a start.
paralle universes could exist in theory as we might not be able to go forward or back but we can go sideways and take different paths which then creates different futures and pasts etc.

what i like to think which makes me smile is we are all time travellers everytime you move your travelling in time lol
