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.
