So, in fact EVERYTHING HAPPENS NOW. THE REAL IS NOW. The past is gone, the future is still the imagination, LIFE IS THE NOW HERE. THERE, when you approach to HERE.
What you call TOMORROW will be NOW. And what you call now will never be a thing of the past if you have no memory. So it's not exactly true when we say that time is moving. Time does not move! Because physically, everything that moves must have speed.
Well, is there a unit of speed for the movement of time? THERE IS NO. Existing, precisely time is always a concept that defines the speed of movement of an object in the dimension of space (x, y, z).
That is why time is called the fourth dimension (t). Space defines where things are positioned, and time is used to define how long (t) something is in the dimension of space (x, y, z).
