As we know that gravity “accounts for the very existence of the Earth, the Sun, and most of the macroscopic objects in the universe”. Nearly every current theories relating to Cosmology are still based on the study of gravity that Newton had studyed three centuries ago, although lots of remedies had been made. Since Big-Bang theory comes out the original force generated by Big-Bang (I call it O-Force) should have existed in every corner of the universe for billions of years and still driving the universe to continually expand. The power of the O-force is obvious. I even imaged that this force are preventing our universe from the start of the Big Crunch and being crushed by other universes! I can also see that the characters of the O-Force are opposed gravity. It comes from a single source where it has no mass. The direction of the force is pointing away from the source. (Check with the characters of Gravity) However it appears that nobody noticed this and no study on this had been done. Can any body tell me why it is not as, if not more, important than gravity in terms of Cosmology?
