Gravitational wave

Gravity wave
National Science Foundation, NSF and their announcement of detection of Gravitational wave by their Laser Interferometer Gravitational Observatory, LIGO can make a rapid advancement of physics research and discoveries of another mysterious of the universe. NSF already announced that they have able to detect gravitational wave. This announcement of detection of gravitational wave have been made a powerful insight into Einsteins general theory of relativity. Because, the existence of gravitational wave in universe was predicted century years ago by Albert Einstein by his general theory of relativity. In general theory of relativity, Albert Einstein predicts gravitational wave as the ripples of space time. According to general theory of relativity Gravitational wave is a ripples of space time curvature and it propagates as wave. General theory also predicts about the transport and propagation style of gravitational wave. general theory of relativity predicts the transportation of gravitational wave as gravitational radiation. In terms of gravitational wave general theory of relativity and Newtonian theory of gravitation is somewhat difference in some extant. Gravitational wave is absent in Newtonian gravitation theory.



Attractive force

The force acting among the objects that tends to closer together is attractive force. The opposite concept of attractive force is repulsive ...
