Support for a local variable lightspeed inside an ellipsoidal transition zone around the earth.
According to Quantum FFF Theory, the earth gravity related LASOF ( Local A Symmetric Oscillating vacuum Frame) is dragging the lightspeed inside an ellipsoidal shaped speed transition volume around the earth inside the solar reference LASOF, with full extinction effect at the edges.
The Michelson and Morley experiment observed that at the earth surface there is NO vacuum or ether effect.
However at higher altitudes there seems to be an ellipsoidal transition zone .
