<p> The present work calls attention to an undeclared assumption made by Einstein in
his landmark paper [Ann. Physik <b>17</b>, 891 (1905)] in which he introduced the
special theory of relativity (SR) and the Lorentz transformation (LT). The
emphasis in textbooks and periodicals is always on his two postulates of relativity
(the relativity principle and the constancy of the speed of light in free space), but
some of the well-known results of his theory such as Fitzgerald-Lorentz length
contraction (FLC) and the symmetry of time dilation (two clocks in motion each
running slower than the other) are based just as directly on the latter assumption
as on the two postulates. Moreover, an argument is presented to show that this
assumption actually stands in conflict with the light speed postulate. It is shown
instead that a different assumption is consistent with both relativity postulates, as
well as Einstein’s velocity addition theorem (VT). It leads to an alternative
version of the Lorentz transformation (ALT) whose predictions regarding length
and time measurements by moving observers differ significantly from those of the
LT.
