Abstract [en]

The Michelson Morley interference experiment of 1887 indicated that the velocity of light is independent of the velocities of source and observer. This surprising result was in conflict with earlier calculations. To make theory and experiment in agreement Lorentz stated a contraction of rigid objects parallel to velocity. We discuss if this contraction is real or caused by the interference method of measurement. Our approach is to introduce a sphere of observation based on ultra short light pulses combined to ultra short observations. When the experimenter travels at high velocity this sphere is according to Lorentz contracted into an oblate ellipsoid. According to our proposed theory the sphere is instead elongated into a prolate ellipsoid. The result of this effect is that stationary objects appear contracted. Our results are in full agreement to Einsteins Special Theory of Relativity. To support our statements we introduce a novel method to measure the length of a travelling object that is independent of interferometry.
