Time and Space Are Mutually Inherent Property of Each Other, Where the Dependency of Time on Space Can Be Termed as Space-Time and the Dependency of Space on Time Can Be Termed as Time-Space

Prasenjit Debnath ^[35]

Abstract: Basically, the physical time and space are mutually inherent property of each other. The analysis of space and the physical time notably started since Euclidean. In the non-relativistic classical theory of mechanics, the usefulness of Euclidean space instead of Einstein's space-time is appropriate, because the physical time is treated as universal property of the Universe with a constant rate of passage that is totally independent of space or the state of motion of an observer. In the relativistic point of view, the physical time cannot be separated from the three dimensional space, because the observed rate at which the physical time passes for a particle or object depends on the object's velocity relative to the observer and also on the strength of gravitational fields, which can slow down the passage of the physical time for an object as observed by the observer outside the field. Thus, in classical mechanics, the physical time and space are mutually independent of each other. A highly successful attempt made by Albert Einstein to combine the three dimensional space with single dimensional time to form a four-dimensional space-time. The concept of space-time combines space and the physical time to a single universe. Mathematically, the space-time is a manifold consisting of events which can be described by some type of coordinate system of reference frame. Typically, the three-spatial dimensions (length, width and height), and one temporal dimension (the physical time) are required in the theory of relativity where all dimensions are independent components of the coordinate grid (reference frame) needed to locate a point in a certain defined space. For example, on our globe, the latitude and longitude are two independent coordinates which together uniquely determine any particular location. In Einstein's space-time, a coordinate grid of reference frame that spans the 3+1 dimensions locates events (rather than just points in space), i. e. , the physical time is added as another dimension to the coordinate grid of reference frame. This way the coordinate grid of reference frame specifies where and when events occur. In this paper, I will have a different and modified explanation of space-time and I will introduce another new term time-space which is different compared to space-time. The dependency of the physical time on space can be termed as space-time and the dependency of space on the physical time can be termed as time-space. Both space-time and time-space are different as both space and time are two different exposed property of the mystical Universe. They link each other and each of them effects on each other but they are not equivalent at all.
