  The law of balance of angular momentum is shown to imply the existence of
absolute time, a fundamental physical quantity that is independent of the
motion or position of the observer. Absolute time implies the notion of
absolute simultaneity, which in turn leads to the notion of absolute distance
between two points. The existence of absolute space follows as a consequence.
These concepts apply to every field of physics to which the angular momentum
balance law applies, and in particular to the theory of special relativity. The
paper also shows that in a vacuum, the independence of the speed of light from
the motion of its source makes it possible to determine the absolute positions
of all points in space. The same independence also allows us to determine the
state of absolute rest or motion of a reference frame from within the frame
itself.
