Thanks, for the help. I have done an extensive search and nothing seems to be out there on calculating the liquid interactions.

gravity
Gravity would more than likely dominate, unless you worry about an atmosphere and then scattering or density variations, as well as refractive index variations (optical fiber) could trap the light. Black holes etc.. trap light through gravitational force
Does Maxwell Boltzmann hold for liquids? In the case of gases it does quite well for calculating the velocity distribution given a temperature. However, when the molecules are closer together in the case of liquids, how do the van der waals force and others effect the velocity distribution...
