Preface
(A) To Part – I (Theory of Gravitation):
At present there are many theories about gravitation along with Einstein’s relativistic theory. But none of the theories has come out successful. Here a theory, which is a complete solution to the gravitation, is given in a simple manner that has been named here cosmic pressure that can explain the attractive nature & long range of gravitational force & can also explain the equivalence principle. Here a gravitational force has also been derived with the help of this theory, which almost coincides with that of Newton. This theory can also give the explanation of nuclear force, molecular binding energy, electrostatic repulsive force, the expanding universe, the weak force, the black holes & the cosmology.
(B) To Part – II (Theory of Light):
With help of the base of part I, part II is also based, & it is mainly a research & in this research the actual nature of light is found out & to do this, the wave nature of light is completely cancelled & its particle nature is fully established in all respects, & thereby dual nature theory of light, & Einstein’s special theory of relativity & Quantum mechanics which are based on the dual nature theory of light are thrown into jungle, & Galilean relativity & Newtonian mechanics have regained their previous status.
