We present measurements of one-way times of flight of 25 fsec laser pulses, along a given distance, in different directions in space. Using autocorrelation, a technique that dispels the need for clocks and their synchronization, we obtained full isotropy. Einstein showed [1] that stars confine their local spaces and concluded that space is a "compressible fluid". Any static instrument on Earth is thus stationary relative to its local space and should yield isotropic results, as we have obtained. Our results validate the second postulate of Special Relativity [2] and support Einstein's idea.
