The history of Big Bang started 300 years ago, when Newton found his law by mathematics. He did not see that the spherically symmetric field of gravity also demanded spherically symmetric form in gravitating bodies. So, his law must be applied to small elements and integrated over the body. Then he would have found that his law can be united with Fatio’s model by assuming attenuation of ether flow inside every point in the body proportional to density. So, not so many particles are leaving the body due to this attenuation. We therefore get an ether wind in radial direction to the body. This ether wind is the cause of gravity.
