The formation of the Universe begins with the Big Bang phenomenon. The Big Bang is a periodic motion, like a planet that starts its movement from one point and returns to the initial point after a complete period, which we name a Cycle period (like a year).
So, in the Big Bang phenomenon, the Universe stretches in all directions like a spring and reaches its maximum radius, then passes along the returning path and arrives at the starting point.
In the forward path, the Universe expands with two linear and rotational movements. In linear motion due to its negative acceleration, it reaches a point at which the linear velocity is zero (return point). But according to Hubble's law, its rotational speed value is always positive and increasing.
In this paper we are going to study the Big Bang phenomenon which has about three stages.
