There seems to be considerable disagreement in the field. Why is it news (I really would like to know!)? + Kobakhidze explaining neutron experiments: https://arxiv.org/abs/1108.4161 + http://physics.stackexchange.com/questions/4289/is-gravity-a... + Lubos Motl: http://motls.blogspot.nl/2010/01/erik-verlinde-why-gravity-c... and http://motls.blogspot.nl/2010/01/erik-verlinde-comments-abou... It's nice to see that also experts in these highly specified fields quarrel about what it means to be "entropic" and "irreversible", etc.

the paper is surprisingly readable (although i don't know enough to say whether it's correct or not) - http://arxiv.org/pdf/1108.4161v1 this is a pity - it would have been a very cool approach if true. the criticism seems quite general, unfortunately (it identifies some consequences that come from associating gravity with entropy and shows that they conflict with experimental results). the paper / main link is a theoretical argument based on an earlier experiment using neutrons and gravity. that earlier work is critical because it ties together QM and gravity observationally (very hard to do…
