I started to go over Verlinde's paper (http://arxiv.org/abs/1001.0785) and I'm just not convinced of what he's doing from the start.
At (3.5), he is assuming there is a particle within one compton wavelength of the holographic screen. Saying this immediately seems to imply that the momentum has an uncertainty on the order of mc, making this particle relativistic. From this, we get F = ma. How is it that that doesn't seem strange? My line of thinking is that we have this particle localized to an uncertainty in the position corresponding to an uncertainty in the momentum that by itself is relativistic. So the actual momentum must be far beyond that. Then we bring in Unruh, something that is relativistic, and what pops out is F = ma, something that is non-relativistic. This seems strange. Can someone... put my mind at ease as to why this isn't all that strange?
