The causes of the contraction in the direction of motion. Metric of Universe. The Causes of Red Shift

Poincare and Einstein supposed that it is practically impossible to determine one-way speed of light, that’s why speed of light in different ways may differ. They also supposed that till there is no the experiment which would depend on the value of one-way speed of light, it is possible to consider that all one-way speeds of light are equal to two-way speed of light. It is offered the explanation of the experiment connected with “Red shift” with the aid of one-way speed of light, therefore it is shown the dependence on magnitude of one-way speed of light. Mechanics is set up based on the unidirectional speeds of light. For example, the experiment of Michelson-Morley is explained with the aid of this mechanics. The cause of the inception of Fitzgerald contraction is explained.
