The force that keeps us together.

So far ,we have covered the beginning of the universe with the "Big Bang" and what happened a few seconds after the Big Bang.
                 After the initial bang ,a mysterious force intervened which became vital for the creation of the galaxies, the stars , the earth and us. A force common in our everyday life and without it, space and time would cease to exist and us along with it. Scientist don't know if it was created during the Big Bang or existed before. We call it gravity.
                 Gravity, an attractive force that always acts between particles of matter. It is stable and predictable, it is invisible. We know it exists because of it's effect on everything. You cannot shield yourself from it and it's power can penetrate anything even across the entire universe.
                 Scientist have concluded that if gravity was just a little bit stronger or weaker the universe could not support life or even exist. It is just perfect for us.
                  Another piece of evidence of design in nature or just a lucky chance of this force originating out of Chaos, you have to think about that. It is impossible to calculate the odds that one throw of the dice would produce this perfect and powerful force of nature.
                  To be honest, scientist have many theories to try to explain this, such as: multiple universes, where there are trillions of universes that pop in and out of existence and we are the lucky one in a trillion that blossomed.
                  So far, there is no evidence of multiple universes.There is only evidence of one, ours.
