Introduction
For example, let us take the simplest equation: distance = speed x time. Time in this case means duration of motion. If speed is given, we can calculate the distance that an object or particle has done in space. In the Theory of Relativity, time as a �fourth� coordinate of space-time is a �coordinate of motion�, and describes the motion of massive bodies and particles in space. Fourth coordinate X4 = c x i x t is called the �time coordinate�, whereas c is light speed, i is an imaginary number and t is the number representing duration of material change. With �time coordinate� one describes motion of objects in space. With clocks one measures the interval between material change X and material change X + n, where n represents the number of units of time. The smallest unit of time is Planck time; in Planck time, photons pass a Planck distance. Time is a measure of motion in space. Lynds defines time as: "Time enters mechanics as a measure of interval, relative to the clock completing the measurement� (1). Space-time is a math model only; space-time does not exist as a physical reality. With the model of space-time we describe motion of objects and particles in space. There is no evidence of space-time existing as a physical reality. Before Einstein created the space-time concept, no one imagined that space-time is a stage of the universe. Today most physicists believe that universe exists in space-time as a fundamental physical reality, however there is no evidence or experimental proof of that (2,3,4,5,6). Space itself is atemporal. Motion of objects and particles does not happen in time, it happens in space only. Time is not running in space independently and is also not a part of the so called space-time as a fundamental physical reality. Space is atemporal and time is a coordinate of motion invented by man and describes motion in an atemporal space.
Humans experience atemporal
space as a present moment. Past and future exist only in the mind;
physical past and future do not exist, there is only atemporal space.
All experiments in physics always run in the present moment, because the
present moment is the only thing that exists. We are not aware yet that
present moments do not follow each other in the line
past-present-future. Time as a �measure of motion� is not an elementary physical quantity like energy, matter, space and motion are; time exists only when we measure it. Time was invented by man in order to describe motion in atemporal space. We have to distinguish between: |
