Abstract An instantaneous velocity where a moment of the clock only corresponds to an arbitrary distance or position in space cannot be implied in Axiom 1, but it indicates that there is only one dimensional existence, space or time, where a certain moment only corresponds to itself specifically, not to any other time or any given length of space. Further , a definition of velocity that consists of two dimensions representing the relationship between space and time is not valid and there is only one-dimensional space or time that is independent of each other in Axiom 1. As a result, the principle of relativity and the principle of the constant velocity of light are replaced by the principle of an inertial system and the principle of universal invariant velocity in Axiom 1. Unlike two dimensions whose magnitude is determined by the ratio, the magnitude of a single dimension is determined by the unit values of one dimension, which indicates that an infinitely great velocity is meaningless. Further, if the two inertial systems are infinite versus finite in Axiom 3, then this extension of the infinitely great velocity can be defined as inextensible.
Abstract The infinitely small is defined as finite length quantity of one dimension without the sizes of space ,while the infinitely great is reached by the superpositions or accumulations of infinitely many of the finite quantity by the way of the change of direction. The change of direction indicates that there is an leap from a finite quantity to finite quantities of infinitely many(infinitely great) and the form of manifestation of infinitely great is one quantitative continuum that can not be carried out by any algorithms and all parts of space (including circumferential length) we see is this one quantitative continuum. The any value is the value of this one quantitative continuum implied the infinitely great that compresses any quantities outside of it to zero.
