When applying the formula of light propagation in moving systems to the motion of the Earth (as a component of the Milky Way Galaxy), the radius of the universe and the time period required for the development of the cosmos can be estimated. With the rate of this expansion and the alterations in surface gravity, tilt, and motion of the Earth, a ‘short evolving distance’ can be determined. Knowledge of the entire plane angle (2π) and the deviating angle of a light beam (α) passing through different value of Earth’s surface gravity renders it possible to determine large distances by utilizing the rules of trigonometry. This ‘long evolving distance’ can be converted into ‘evolving time’ by dividing it by the speed of light. Based upon this dating method, at a figure of 3.1415 redshift, the universe may have been formed 13.6879 to 13.8498 billion years ago, with a mean value of around 13.7536 billion years. In this model the alterations in the parameters of the Earth affects the radius of cosmos, modifying its size and shape.
