What is Einstein’s General Relativity Theory? A Very Simple And Brief Explanation.

General Relativity Theory

In the year 1916, world famous scientist, Albert Einstein published the general theory of relativity which is basically the geometric theory of gravitation. This is popularly known as the general theory of relativity and presently in modern physics it gives the description of modern physics. This theory of general relativity generalizes Newton’s law of universal gravitation and also the special relativity theory. Thus, general relativity theory gives a united or complete description of gravity in terms with time (space time) and space and as a geometric property.

This theory further refers to the understanding and concepts of space time in direct relation to energy and momentum and where radiation and matter are present. This direct relation is specified by Einstein along with the theory in his field equations and where he sees this relation as a system of partial differential equations.

On many predictions, this general relativity theory is different from classical physics. Some of these differences of predictions are the geometry of space, particularly about the passage of time, the movement of bodies in free fall, and the transmission of light, gravitational lensing, gravitational time dilation, the gravitational red shift of light and the gravitational time stoppage. Whatever the predictions of the general relativity theory have been taken is confirmed with all up-to-date concepts. But, it is to be mentioned here that general relativity theory consists experimental data and is regarded as a simple theory of gravity. There are other relativistic theories of gravity which are also essential and general relativity is not the only one here. Hence, discussions are still going on to know hoe general relativity theory can be patched up with the laws of quantum physics. This advanced experiment is going on because it is important to generate a full fledged and established theory of quantum gravity.

Whatever it is, general relativity theory of Einstein has significant astrophysical implications. The existence of much called black holes in space is studied and experimented under this theory. The general relativity theory examines the understanding of black holes, through which no one can escape, not even light because space and time is distorted in these regions and which are known as the end state of huge stars.

This theory is strongly stood as an observant of some astronomical objects which emit intense radiation with black holes. At the same time, general relativity theory also predicts the continuation of gravitational waves. This is extremely important for projects such as LIGO and NASA/ESA Laser Interferometer Space Antenna. Furthermore, general relativity is the root of existing astrophysical models of a constantly increasing universe.
