Here are some concepts which differ from the relativistic theories on the behavior of light, enabling us to better appreciate the way we perceive things that happen in our universe. We see that the space-time does not bend if not instead of it. The light changes its path due to the speed at which it is issued. We will see that the way of perceiving the curved space time is nothing but a way of understanding things better, and that light is that we can perceive objects because they reflect light. Causing us we should appreciate the behavior of space-time as if in fact this curve.

Deductions synchronizing two pulses of light and one of them we do undertake a high-speed space travel and the other on earth we leave, as in the experiment of the twins mentioned by Einstein in his theory of relativity. It can be shown that instead of bending the space-time by the great speed that carries the spacecraft, only modified the path of light by the speed you have purchased. Figure 1 also can establish clear that time must pass to reach a certain point anywhere in space, even adding spatial reference frames (x, y, z). Also, one can predict the time lag between the observer and the observed point, it can be shown that light has several stages (IDEM Einstein). It may be noted that the observer sees the source from any position, not so for the points where light travels in a vacuum. In addition, we can see the light reflected from the solid always considering the delay time for any frame of reference. Since this is the reason that a train entering a tunnel at high speed, is seen by an observer outside the train. To the observer it would seem that the train is smaller than it really is. We leave some basic points to make the case: o The light travels with velocity independent of the framework (IDEM relativistic theories) or the light acquires a non-relativistic speed, ie, that can move at any speed and mechanics
