Something new about time

Imagine an Einstein-train is running at a velocity greater than that of light. When the last car of the train is passing the railway station, a light is flashed on the platform of the station and - simultaneously - in the last car of the train. For an observer on the train who is sitting in the first car the lightwaves approach at a velocity of c according to the law of the constant propagation of light. For a second observer on the platform of the railway station, however, the distance between the front of the lightwaves and the head of the train ist constantly growing according to the law of the constant propagation of light! But how do the lightwaves mange to reach the head of the train for one observer, while not reaching it for a second observer? As soon as it comes to velocities greater c (of two reference-systems), the relativistic paradox takes a new shape. Astonishingly, the existence of such reference-systems is not excluded by the laws of nature, provided the escape velocity of the two reference-systems is a consequence of the expansion of space. In this booklet a strict solution of the paradox is presented, which, in turn, entails drastic consequences for the nature of time. The first chapter contains a brief summary of the Special Relativity Theory for those readers who are not physicists.
