Wide binaries as a critical test for Gravity theories    [PDF]

X. Hernandez, M. A. Jimenez, C. Allen

Assuming Newton's gravity and GR to be valid at all scales leads to the dark matter hypothesis as a requirement demanded by the observed dynamics and measured baryonic content at galactic and extragalactic scales. Alternatively, modified gravity scenarios where a change of regime appears at acceleration scales $aView original: http://arxiv.org/abs/1205.5767
