Schwarzschild Cosmology

Authors: C. A. Laforet

The internal Schwarzschild solution is examined in the context of a cosmological model. An examination of the Hubble parameter and redshift is made and it is shown that the model agrees with cosmological data in predicting the transition redshift when the expansion of the Universe changes from deceleration to acceleration. Distance modulus is plotted against redshift and compared to cosmological data. The consequences for an observer in freefall in a local gravitational field are then examined in the context of this model. It is shown that the model predicts an accelerated expansion that agrees with current observations of the expansion history of our Universe, namely that the initial expansion is infinitely fast, and then the expansion slows for some time followed by an accelerated expansion.
