Ah i see masterp.. but if there are these neutrinos, wouldnt by theory (since the are a massive particle) they have to propagate some sort of gravitational properties? (and as i understand it we dont really know what gravity is either, rather we just have models to demonstrate the effects of it)

www.thefinaltheory.com... - new book on which this discussion may be already solved

Milgrom's theory has been worked on by a number of astronomers since and Dr Zhao and Dr Famaey have proposed a new formulation of his work that overcomes many of the problems previous versions have faced.

They have created a formula that allows gravity to change continuously over various distance scales and, most importantly, fits the data for observations of galaxies. To fit galaxy data equally well in the rival Dark Matter paradigm would be as challenging as balancing a ball on a needle, which motivated the two astronomers to look at an alternative gravity idea.

Basically this theory proposes that our understanding of Gravity is flawed and that it acts differently at different distances. Quite a fasinating theory actually.

Allthough it still doesn't touch on what Gravity actually is.
