A physicist named Jose Cembrano may have an explanation for Dark Matter that stems from quantum gravity:

This may allow for tests to be conducted.

Do you have a link that doesn't require a login?

A Google search turns up nothing for Jose Cembrano having anything to do with dark matter.

A search of arxiv.org turns up no papers with Cembrano as an author.

I managed to track it down, sorta. It is Cembranos not Cembrano. And here is a link to the paper, but you need APS access, which I don't have.

The pdf file is free and here:http://arxiv.org/PS_cache/arxiv/pdf/0809/0809.1653v1.pdf pete

It's interesting that the constraining lower bound matches both the putative bounds on the neutrino mass, and the bounds on a new effect in gravitational theory purported by Prof L. Abbott years ago...~ 3 times 10-3 ev. The annihilation of e+e- pairs of course can produce not only photons, but Z0's, as neutrino/antineutrino pairs in a weak neutral current, and they have already been shown to fit the correct properties for a quantum gravitational carrier, by Gamow. pete
