Time, observer, and consciousness

Abstract

In today’s physics, opinions on what is time are different. Some physicists deny the existence of time, and others think that time has physical existence. Nevertheless, time was never directly perceived by senses. With our eyes, we perceive the flow of material changes, i.e., motion in space. Our recent proposal is that universal space is time-invariant in the sense there is no physical time which would be the fourth dimension of space. The model of space-time is replaced with the model of time-invariant space, where we perceive the flow of material changes. In past years, neuroscience has discovered that linear psychological time “past-present-future” has origin in neuronal activity of the brain. An observer is experiencing the flow of material changes in the frame of psychological time. With eyes, we do not perceive some physical time in which material changes run. The observer perceives a stream of changes that run in the time-invariant space. This stream of changes the observer experiences in the brain through the psychological liner time. In the universe, there is no linear time past‐present‐future, material changes run in time-invariant space. An observer only perceives changes (not time) and he experiences changes in the frame of psychological time. The observer (the subject) is beyond psychological time, and it does not change during a human lifetime. Observer can be understood as the function of consciousness.
