Abstract

Recent neurological research shows that, psychological time (“past-present-future”) is a result of neuronal dynamics of the brain. Through psychological time, we experience motion in the universe. The puzzle with time in physics is that in the universe, we can perceive only motion and not time. Here, it is proposed that physical time, t, is run of clocks. The fourth coordinate,  , is spatial too.  is composed out of an imaginary number i, light speed c and number tindicating “thick” of clocks in space. Precisely, time t is not fourth dimension of space; time t is a third component of the fourth dimension of space. Fourth dimension is not temporal, it is spatial too. Clocks run in space only and not in time. There is no physical time behind run of clocks. Clock/time is a measuring system for physical events.

Key words: Psychological time, physical time, run of clocks, numerical order, frequency, velocity, light speed
