Query: Absoluteness of Velocity Produced by Accelerating Process and Absolute
  Space-time Theory with Variable Scales   It is proved by means of the dynamical effects of special relativity that
velocity caused by accelerating process is not a relative concept. The
influence of accelerating process should be considered in space-time theory.
Besides the Newtonian absolute space-time theory with invariable space-time
scales and the Einstein relative space-time theory with variable space-time
scales, there exists the third space-time theory, i.e., the absolute space-time
theory with variable space-time scales. At present, special relativity is
divided into two parts, kinematics and dynamics. In kinematics, force and
acceleration are not considered so that space and time becomes relative
concepts. This division is completely artificial and irrational. The rational
space-time theory should be established on the foundation of dynamics
consistently. The changing rules of space, time and mass with speed should be
dependent of accelerating processes and with absolute significance. The real
meaning of invariability principle of high speed should be that we can not make
the speed of an object speed with rest mass reach and exceed the speed of light
in vacuum by the method of accelerating object. It is proved that the
absolutely resting reference frame exists. In order to eliminate multifarious
space-time paradoxes in special relativity, and coincide with Big-bang
cosmology, the absolutely resting frame is necessary. A method is put forward
to look for the absolutely resting reference frame. The isotropy reference
frame of cosmic microwave background radiation can be regarded as the
absolutely resting reference frame actually at present.
