Scientific Secrets of Jainism
that if the density or mass of the sun is kept constant and if its diameter is halved, it is reduced to 500th part of its size. In these circumstances, if an object is sent to the sun from infinite distance, it gains a greater velocity even than light before it reaches the surface of the sun. As a result, light is also attracted to the sun with the same force and all the light emitted by the object is again absorbed by it by force of gravitation. Later on, only after a few years, in 1796 A.D. Pierre Simon, the mathematician and astronomist and Marquis de Laplace made a similar note in their essay entitled 'Exposition due System du monde." It means that the inference regarding black holes was made 200 years ago. But these concepts of Michell and Laplace were altogether forgotten till Einstein searched and developed his General Theory of Relativity because nobody knew about this kind of contraction of physical objects in space and on the other hand, the inference of black-holes was based only on the Newton's principle that light is constituted of material particles. Contrarily, Newton's theory of particles with reference to light came to be rejected and scientists accepted wave-form of light. Moreover, they accepted that gravitational force of an object had no effect on light-waves, whereas the effect of gravitational force was the main thing in the concepts of John Michell and Laplace.
In 1911 A.D. when Einstein was a Professor in the Prague University, he for the fist time, calculated the effects of gravitational force of space objects on light-waves. In 1914 A.D. at the time of the total solar eclipse, Einstein tested the results, he had obtained. But since the first World War declared in those days, the subsequent research work had to be cancelled. It was good for Einstein because Einstein's theory at that time was not sound and his calculations were also faulty."
But in the weekly 'Berliner Berichte' published on the 4th, the 11th, the 18th and the 25th of November, 1915 A.D., Einstein fully explained the 'General Theory of Relativity.' 12 According to the General Theory Of Relativity, on account of gravitational force of space object like the Sun which have a tremendous mass, their surrounding space contracts and curves and that is why the ray of light that passes near by it, attracts towards that massive object i.e. it slightly deflects from its straight path. This is called Solar Deflection of Star-light.
In short, the tremendous gravitational force of the sun has an indirect effect
