Abstract: | A cosmological model based on gauge theory of gravity is proposed in this paper. Combining cosmological principle
and field equation of gravitational gauge field, dynamical equations of the scale factor R(t) of our universe can be
obtained. This set of equations has three different solutions.
A prediction of the present model is that, if the energy density of the universe is not zero and the universe is
expanding, the universe must be space-flat, the total energy
density must be the critical density
ρc of the universe. For space-flat case, this model gives the same solution as that of the Friedmann model. In other words, though they have different dynamics of
gravitational interactions, general relativity and gauge
theory of gravity give the same cosmological model. |
