  Two complementary and equally important approaches to relativistic physics
are explained. One is the standard approach, and the other is based on a study
of the flows of an underlying physical substratum. Previous results concerning
the substratum flow approach are reviewed, expanded, and more closely related
to the formalism of General Relativity. An absolute relativistic dynamics is
derived in which energy and momentum take on absolute significance with respect
to the substratum. Possible new effects on satellites are described.
