AB - Experiments with ultrashort laser pulses have indicated that the intersection of a rotational symmetric ellipsoidal by a flat surface at any angle appears circular when studied form one focal point of the ellipsoidal. This statement is mathematically proved for the general case. The spherical coordinate system of an observer that travels at ultrahigh velocity appears transformed into an ellipsoidal coordinate system but this fact is hidden from sight by said statement. If this was not so, his absolute velocity would be visible to the traveling observer in contradiction to Einstein's postulate.
