At last an answer to how gravity is created, ever since Newton’s explanation of gravity and since cavendish’s demonstration where observers noted that 2 masses moved towards each other it has been ,reasonably enough, assumed that there is an attraction between masses.  However, for most of that time nobody knew that the Milky Way was only 1 galaxy among hundreds of millions and that this entire universe is over 99% Empty thus we now realised that the most important component in the universe is space. The thing that makes the difference is random motion which through collisions and minor hits acquires spin. This spin now contains energy forever and pulls space in a tiny stream to itself forever. Trillions and trillions of these particles are continuously created. Eventually masses accumulate and continue to pull space itself. Thus individual particles are the sole source of gravity.

Why is gravity so weak?  Because it is made of empty space!  Space in motion.

Space is a continuum since there is nothing else.

Over billions of years multiple complex properties are made all founded on gravity.
