Why Do Astronomers Still Believe That All Cosmic Light Moves Towards Little Planet Earth At Precisely c?

Why is the whole of astronomy still based on Einstein's unproven
postulate that light always travels at c. The one way speed of
starlight has never been directly measured and the postulate is just a
variation of Lorentz's aether theory anyway. If the postulate is
wrong, as investigation into variable star behavior strongly suggests,
then the repercussions for astronomy are enormous.

After twenty years of studying this subject, I have written a thesis
which revives the old argument that light is ballistic, at least when
traveling between completely unconnected objects across deep space. It
contains radical modifications and improvements to the earlier theory
of Walter Ritz, whose death in 1909 virtually saw the end to the
proper development of his 'Emission Theory'.

The paper is basiclly descriptive and contains some VBasic .exe
programs written by myself that can be ignored if so desired.
