...Isn't it pretty clear this entire page is just part of an April Fool's joke? The joke can be seen here. If "rainbow gravity" is a real thing that's been around for years, then why (1) was this page started just days before April 1 2015, and (2) how come there are no peer-reviewed papers cited. Have a look at Modified Newtonian dynamics or Loop quantum gravity if you want to know what an *actual* page on a gravitational theory looks like.
