According to the motions of the universe which includes the rotational motion that is proved byHubble's law and that of linear which is a motion with negative acceleration, the equations of motion can be written for the universe. On the other hand, we have calculated the initial energy released from the Big Bang explosion by Monte Carlo technique, and the amounts of 10110 joules was obtained. Some of this energy is used for creation of the galaxies and stars, which have a mass of about 1053 kg, and the amount of initial energy is reduced.
So, it can be said that the linear velocity of the universe decreases with the passage of time and reaches zero at the end, and when the amount of linear energy becomes zero, the rotational energy achieves its maximum and from that point universe start its back motion toward the center of universe.
In this paper we are going to calculate the time of the universe from beginning to end.
