Gravity is the force of nature that pulls cellestrial bodies toward one another. The cause of gravity is the enertia of a bodies movement through space and time. This happens by an object preconcievably traveling through the cosmos at an alarming rate of acceleration. The faster an object travels the more enertia it will build up and then will therefore have a greater ability to move. the more it moves the more other objects will cling to it. the way this can be proved is by taking an object and hurtling it towards another object the two objects would collide do to the enertia pulling them towards each other. Thy would not stay on their current trajectory but their paths would alter towards one another in a greater force than their initial gravitational pull. the best test to accomodate this theory would be tow baseballs flying through the air at speeds over one hundred miles an hour. The baseballs would not interject themselves with one another normally but at this speed would do so do to the balls enertia pulling them towards one another.
