Scientific Secrets of Jainism
For the common man, the structure of the black-holes was very impressive. Even so, the black holes were for them nothing more than a mere imaginary science fiction, a cosmic picture-story or a newish subject-matter of making feature-films.
Modern scientists believe that the black-holes have a very strong gravitational force and even light cannot escape from their gravitational force and that is the reason why they cannot be seen.
This inference of scientists is based on scientific principles and their mathematics. According to their inference, stars which have as much mass as nearly ten times the mass of the sun of our solar system and which are in very distant and deep regions of the boundless universe become supernovae at the end of their life-span. In other words when they cannot bear their own internal pressure - attraction and repulsion - they burst out with a tremendous explosion and then on account of tremendous pressure of their own gravitational force, they go on contracting and became so small that compared to the whole universe which is as expansive as thousands of millions of light-years, their volume is reduced to the point of negligibility. The volume of the stars having as much mass as ten times the mass of the sun of our solar system is reduced to the diameter of only 60 kilometres. For that reason, its gravitational force rises tremendously and it soon begins to attract all the objects to itself and gulps down all that comes to it. It again absorbs even the light emitted by the same supernovae i.e. itself. As an object, a stone, a ball etc. tossed from the earth, returns to the earth, to the centre of the earth by its gravitational force, so the light emitted by the contracted supernovae star, is again absorbed in the centre. Moreover, it does not allow the reflection of the light that falls on it from other external illuminated objects. As a result, those stars cannot be seen. Only something like black points are seen in the direction. That is the reason why they are called black-holes.
We are all familiar with the concept of escape velocity, i.e. velocity to escape from gravitational force. If a small stone is tossed from the surface of the Mars to the phobos, the satellite or moon of the Mars with the force and velocity with which it is tossed from earth-surface to space, it reaches its orbit or goes up 9000 kilometres high in the orbit of the phobos, the satellite of the Mars and become a satellite of the Mars because the gravitational force of the moon phobos of the Mars, is so slight that there, the velocity to escape from
