I thought MOND only kicked-in in regions of a galaxy where acceleration was much lower than in the Sun's region. These guys appear to be reasoning that because the Oort Cloud is far from the Sun (i.e. relatively low acceleration) then MOND might apply. But isn't part of the reasoning for MOND that its effects can't be tested anywhere near Earth, because this whole galactic neighbourhood experiences much too much acceleration? The article was very thin on explaining how MOND could explain anomalous orbits of Oort Cloud objects, or what kinds of anomaly they are trying to address.
