I don't think anyone has been able to derive an explicit prediction of this from string
theory. Most string theory calculations (e.g. black hole entropies) have been done in a
kind of approximation on a flat space background, but to compare to the LQG calculation
they would have to do an exact calculation.

LQG predicts that the speed of light depends on photon energy.
This has been falsified by Fermi telescope observations of gamma rays
over on order of magnitude variation in energy. All photons arrive at the same
time.

*****The Holographic Principle---A rational justification for idealism*****.
The holographic principle seems to be an epplication similar to
discretization of
continuous signals. In that case, there is no loss in information in
converting a continuous time signal into an indexed set of point values, as
long as the sampling rate is twice the highest frequency in a continuous
signal.
This might be a physical vbasis for Leibniz's discrete samplings of
images giving the "whole" picture.
Continuing that line of thought, and under the proper cicumstances,
(from 3 to 2 dimensions) >> infomation in a volume = information in the
volume's
surface.
(from 2 to 1 dimensions) >> infomation in a surface= information in the
moving
line describing the surface
( from 1 to 0 dimensions) >>
>> infomation in the smoving line = information in an indexed set of signal
values
Monadization of a 3d physical violume would then be successively
3d to 0d mental point
