The effects of gravitation propagate from one place to another rapidly according to the Newtonian theory. The concept of space and time unitary converted into four dimensional flat spice time with the arrival of the special theory of Einstein’s in 1905 then the problem starts visible with the Newtonian theory. The present guide of all physical theory includes the c = 3 × 1010 cm s-1, speed of the light and it is the highest speed which is allowed to the physical particles. There can be no immediate propagation. The compatibility of gravitational force and the spirit of special were discovered by Einstein after the decade of research then he come up with the theory of general relativity in the year 1915 and it is the prototype of all the theories of modern gravitation. The intellectual jump of colossal is the main ingredient in the concept of gravitation but as the demonstration of curvature of speed and time the idea is previously introduced by the Ceorg Bernhard Riemann who is the mathematician in a rudimentary form in the year 1854. The theory of gravitation was transformed from the theory of forces into the dynamic theory of geometry which is the first dynamic theory with the four dimensional curved space times. The gravitational redshift was the first prediction of Einstein. The waves which are spreads awayfrom the gravitational mass such as light then the frequencies are reduced by the proportion to the change in the experience of gravitational potential by the wave. In the solar observations the redshift are measured and by means of clock flown of high precision in airplanes. However the redshift is already measured without invention of general relativity. The modest argument which is owned by Alfred Schild states that under stationary circumstanced the redshift can be displayed by wave propagation when the usual relationship o geometric implicit in Minkowski space time which are violated (Brown, H. R., & Read, J., 2015).. The shape of space-time must
be curved. The redshifts observations reflect that the space of space-time must be curved in the vicinity of masses irrespective of the precise form of the theory of gravitation. The ten equations relating the material energy momentum tensor with the metric is provided by the Einstein. The constant G and c are previously mentioned in the field equations by the Einstein as a parameters and the equation of Poisson is replaced by it. The Newtonian law of motion is replaced by the Einstein with the statement that particles of free test move with the geodesics and it is the shortest curve in the geometry of space-time. The general relativity in the aphorism is encapsulated by the influential gravitational theorist, named John Archibald Wheelerin which the curvature states how to move and space-time states how to curve (Wheeler, J. A., 1968). The experiment of Eotvos-Dicke-Braginsky states with the high precision that the particles which are free that is travel with the same trajectories in space-time, but redshift of gravitation reflects that the universal trajectories needs to be similar with geodesics. The predictions presented for the General Relativity were seen to approach the Newtonian theory(irrespective to the contrast between the both) where the comparing velocities were small as compared to the gravitational potential and c value which were seen to be weak enough not to cause larger amount of velocities (Bekenstein, J. D., 2004). This has led to calculation of earth, star, stellar structure with the motion features of the solar system by using Newtonian theory without any chance of error. Two predictions were presented by Einstein for studying General Relativity. A slight deflection is seen among the light beams that pass near the gravitating body and this deflection is proportional to the mass of the body. Stellar images taken from the 1919 total solar eclipse helped in verifying the observation and caused the deflection of quasar radio images by sun. This
