time has welded to space .so, retu is impossible ( Dr Naader Noory )

    A new definition of time:

Time is a contractual quantity that is used by a chronographer (human) using a timer (clockwise rotation; the rotation of the earth around the sun, etc.) to express

the duration of a process (trend, changes ,etc.). 

 Time can never go back, because the retu of time definitely requires a complete retu of space, and because this retu requires

infinite energy,

it is impossible to retu to the past.

remember, time has welded to  whole space
