Gravitational radiation and observational cosmology
Recent observations by Weber indicate that a high flux of gravitational radiation is now being generated within the Galaxy. Assuming our environment to be typical, we must expect all galaxies to behave similarly, leading to large total amounts of gravitational wave energy in the cosmos. We have constructed an evoluational model for the generation of gravitational radiation subsequent to galaxy formation and examined how the dynamics of the Universe are affected by the conversion of matter into radiation over a time scale of several billion years. If our Galaxy now converts more than 100 M/sub sub solar / per year into gravitational waves, we find that this radiation can play as important a role as matter in the evolution of the Universe. We use the latest values of the Hubble constant and deceleration parameter and find that the lifetime of a radiating cosmology is shortened from the Friedmann value to lie in the range 11 to 14 billion years.
