Deformation of spheres

Instead of an assumed contraction of fast moving objects, I have introduced the idea that the travelers spheres of observation by the velocity are transformed into ellipsoids of observation. One advantage is that this new concept is easier to visualize and that it makes possible a simple graphic derivation of distortions of time and space caused by relativistic velocities. Another advantage is that it is mentally easier to accept a deformation of spheres of observation than a real deformation of rigid bodies depending on the velocity of the observer.
