Title

Abstract

In my thesis, I would like to present that the universe’s changes in time can be defined with the use of the relativistic motion equation and the differential and integration calculation procedures widely applied in mathematics; these procedures can also be used to calculate the exact equations and functions that describe the duration, radius, speed, acceleration, and the changes in time of the Hubble constant. For my equations, I also made use of the Hubble relation, after which I substituted the value of H as defined by Dr. Reiss et al in 2009 to calculate the present age, radius, speed, and acceleration of the universe. I then compared the initial and present acceleration data arrived at by the above means with the gravitational constant defined by Cavendish and I thus established that the present rate of acceleration corresponds to the order of magnitude of the value defined by Cavendish. It can also be established that the universe’s acceleration has decreased, meaning that the rate of expansion is slowing.
