تعریف قابل درک زمان

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 return of time definitely requires a complete return of space, and because this return requires

infinite energy,

it is impossible to return to the past.

remember, time has welded to whole space
