The astral system or universe ( or cosmos) is all that was before and it ever will be. However, the concept that the astral system is all is not a scientific fact, but an assumption based upon materialistic naturalism. The contribution of Carl E. Sagan (1 November, 19324 – 20 December, 1996) in this regard was concerned with “extraterrestrial life”. The cosmological evidence proves that, the Physical Constants of the universe (astral system) are serving a lot for it’s fine tuning. It is impossible for system of human established engineering. The series of waves, the ripples in astral system from the original event of Big Bang are detectable at one part in one lakh (100,000). If this component were slightly smaller, then the present astral system would exist only as a collection of gas. Planets and life on earth may not be there. If this component were slightly larger, the astral system would consist only of large black holes. Noticeably, life would be impossible in such a astral system or universe. One more parameter for the fine tuning of astral system is the strong nuclear force. This nuclear force is responsible to hold atoms together. The fusion of higher and basic hydrogen fusion together in astral system is leading to Sun burns. Fusion of two hydrogen atoms is required for 0.7 percent of the mass of the hydrogen conversion into energy. If the amount of matter converted were slightly smaller—0.6 percent instead of 0.7 percent — a proton could not bond to a neutron, and the astral system would consist only of the hydrogen. In absence of heavy elements, there would be no rocky planets. obviously there would be no life. If the amount of matter converted were slightly larger—0.8%, fusion would happen so readily and rapidly that no hydrogen would have survived from the Big Bang. Again, there would be no solar systems and no life.
