Radial velocity dispersion in spheroidal and elliptical galaxies, as a function ofradial distance from the center of the galaxy, has been derived from Cosmological SpecialRelativity. For velocity dispersions in the outer regions of spherical galaxies, the dynamicalmass calculated for a galaxy using Carmelian theory may be 10 to 100 times less than thatcalculated from standard Newtonian physics. This means there is no need to include halodark matter. The velocity dispersion is found to be approximately constant across the galaxyafter falling from an initial high value at the center.
