Resume the last chapter. We have the velocity of the light c = 1. This velocity is the same to ech other kind of the light (menaing the wavelenght). We can recognize only different kinds of light. The red light, blue light, the yellow and more. The differences among them are frequencies. We take a one frequency as a standard (basic unit). The colour of the "light" is microwave Cs 199.

And as we know from our experience we have matter bodies which are travelled through the space with the velocity v which is equal 0,00000001 of c.

How can something travelled through the space with velocity v < c ? How is it possible ?

We know from the anihillation process - the something+ could anihillate with something - to ELMG waves. And the other way.

We can suggest the energy is frozen to some energypack.

How to explain the acceleration. The acceleartion has no use for c = 1.

We have two objects (f.g, two trains). Theese objects are moving to each other at some coordinate system. The velocity of their moving is v = 0.5.* A half of velocity of the light. *

We can expect the same velocity c to each train. But the velocity of two trains is put together with another moving body.

**In the other hand the same fact is known from the definition of the velocity of the light. Without the Michelson experiment. The wavelenght of the light is changing. That means the time and the lenght is different, but in the same ratio. The definition of the velocity of the light will be same in every coordinate system. What can be changed is the period. But the period is limited with the definition of hyperbola. We know, that there is imposible to reach the axis x or y.**

**The light is more energetic as a result of the wavelenght became shorter.**

**We can reach the mass of the universe.**

*It is impossible for a mass to travel to infinity. Why ? Because every mass deforms the space. And if the universe would be sustained from two masses. And if we accelerate theese masses for an escape velocity. The bodies will travell around the deformed space and in the end they will meet. There is no chance for travell to the infinity.*

Why we don´t reach the velocity of the light by the matter bodies ? The reason is simple. The frequency went so shorter and mass grow up. After a while the frequency went to the zero . all the changes could went in the same moment.

We have different experience from our ordinary world. F.e. two trains are moving to each other at a railway station.

To each train is moving the rocket with some velocity to the railway station. As we expect - the velocity of the rocket to every train will be different.

But suddenly we find through the experiment, that the velocity of the light is the same to each objects, in spite of how fast every object is moving to the coordinate system. In the end, the velocity of the light is constant to the coordinate system and to every object in spite how fast they are moving to each other.

The universe was moving 1% per minute. Theese days the universe is moving 0.000 000 01% per year.

To which second ? To second from atomic clock, which are placed on the earth. There is i different between atomic clock on the earth and the atomic clock on the moon. The difference of course is extreme small. But there is.

The same may be used by the infinitezimal calculus. The definition of a derivation when dx is close to zero.

**In the end I would like to mean the Michelson-Morley experiment. It is useless ?**
