  The investigations of the author on a new independent theory of field, termed
a vacuum field theory (VFT), have been presented in four publications. It has
been based on the axioms for inactivated and activated state of vacuum. An
inertial frame connects with vacuum in a limited space. On the basis of the
first axiom and the proven simultaneousness of events in two movable relative
to each other inertial frames and, a new transformation of coordinates, time
and relative speeds of frames has been produced, as well a new law of speed
summation. The covariance of Maxwell equations with respect to the
transformation mentioned has been proven. These theoretical results have been
applied in kinematics, dynamics and electrodynamics and identity of the
relevant experimental investigations has been turned out. In Newton space the
laws of gravitation have been established on the basis of the second axiom, as
well kinematics and dynamics of VFT. The laws mentioned have been used
successfully with examining the gravitational phenomena in the Solar system and
a new phenomenon has been found out, namely the change of the orbit of a
material point with time from close to elliptical into circular.
