Bounds on energy dependence of the speed of light can be used to place
constraints on the effective energy scale for quantum gravitational effects.
Dt ~ x(E/EQG)a L/c
E2-c2p2~E2x(E/EQG)a - This may be modified in some quantum gravity
This has the important observational consequence that this will give
rise to energy dependent delays between arrival times of photons.
E2 = m2c4 +p2c2 - in the Lorentz invariant case,
The expected time delay is :
This may be measurable for very high energy photons/neutrinos coming
from large distances.

~85% of the matter in the Universe is Dark Matter
At most a few % of the matter is baryons
Most people believe that the lightest SUSY particle is a stable neutralino and is probably the dark matter
These are weakly interacting and heavy
