Experimental Evidence in Support of the Possibility That the Local Space of Earth Is Confined

We have measured variations in the times of flight of 25fsec laser pulses, along a given distance from A to B, in different directions in space. Flights from A to B are termed one-way versus two-way - from A to B and back to A. The isotropy obtained, despite the motion of Earth in global space, supports the possibility that the local space of Earth, and probably that of other stars, is confined - captured inside the sphere of the star. To maintain space continuity, despite this confinement, space must necessarily be an elastic fluid, as Einstein, for a different reason, concluded in 1939. In addition, we wonder if this confinement of a local space in a star or galaxy explains its non-participation in the Hubble expansion of space. Our experiment used an auto-correlation technique that dispels the need for clocks, which in one-way measurements require a problematic synchronization scheme.
