aryy, I have a homework for you. Who was Tom Bank's doctoral student and who also hates Verlinde's gravity, which is acknowledged positively in this paper? Keep the name for yourself! :)
Do we have to distinguish between the two discretness ?
1. The analogous fluctuations in a polarized vacuum as a medium for light
2. The digital numbers of the mathematical space as a holographic picture of the polarized photon.
Why don't they distinguish it -"We exclude the random walk model and most of the holographic models of the space-time foam." http://arxiv.org/abs/1108.6005
