Roberts Roberts your criminal (and cleverer) brothers have explained
this in such a nice way:

http://www.logosjournal.com/issue_4.3/smolin.htm "Einstein's Legacy --
Where are the "Einsteinians?", Lee Smolin: "Quantum theory was not the
only theory that bothered Einstein. Few people have appreciated how
dissatisfied he was with his own theories of relativity. Special
relativity grew out of Einstein's insight that the laws of
electromagnetism cannot depend on relative motion and that the speed
of light therefore must be always the same, no matter how the source
or the observer moves. Among the consequences of that theory are that
energy and mass are equivalent (the now-legendary relationship E =
mc2) and that time and distance are relative, not absolute. SPECIAL
RELATIVITY WAS THE RESULT OF 10 YEARS OF INTELLECTUAL STRUGGLE, YET
EINSTEIN HAD CONVINCED HIMSELF IT WAS WRONG WITHIN TWO YEARS OF
PUBLISHING IT."

http://www.pitt.edu/~jdnorton/papers/OntologyOUP_TimesNR.pdf "What Can
We Learn about the Ontology of Space and Time from the Theory of
Relativity?", John D. Norton: "In general relativity there is no
comparable sense of the constancy of the speed of light. The constancy
of the speed of light is a consequence of the perfect homogeneity of
spacetime presumed in special relativity. There is a special velocity
at each event; homogeneity forces it to be the same velocity
everywhere. We lose that homogeneity in the transition to general
relativity and with it we lose the constancy of the speed of light.
Such was Einstein's conclusion at the earliest moments of his
preparation for general relativity. ALREADY IN 1907, A MERE TWO YEARS
AFTER THE COMPLETION OF THE SPECIAL THEORY, HE HAD CONCLUDED THAT THE
SPEED OF LIGHT IS VARIABLE IN THE PRESENCE OF A GRAVITATIONAL FIELD."

  In having universal constancy to the speed of light in a vacuum you end up 
with multi-level expanses or layers of universe in depth. In broad, 
paralleling universes. With velocity your external environment will tend to 
crowd in upon you where it was quite roomy before necessitating transfer to 
an [expanse of external universe environment] friendlier to the velocity --  
or contraction of [that] space and [that] time -- attaining since you will 
be measuring the speed of light the same constant as always.
