I just want to point out that, in my experience, "alternate theories of gravity" and especially those derived from a kinetic basis, tend to be a field that's extremely ripe with crackpots and pseudo-scientists. This is because what tends to happen is - people take some simple math, low-level enough that they can comprehend it, and apply it to this very intricate reality, hoping to strike gold somehow. The kinetic model is simple enough, and understood well enough that you could use math that's accessible even to those who are not actual scientists. Of course, it's never worked. It's a very, very common scenario. Be careful.
