Black Holes

Scientific paper

This paper summarizes results following from the two preceding papers, I and II, on the gravitational radiation emitted in the head-on collision of two black holes, each with energy μ, at or near the speed of light. The radiation (in the speed-of-light case) near the forward and backward directions θ^=0, π, where θ^ is the angle from the symmetry axis in the center-of-mass frame, is given by the series c0(τ^,θ^) =tsum∞n=0a2n(τ^/μ)sin2nθ^ for the news function c0 of retarded time τ^ and angle θ^ successive terms can in principle be found from a perturbation treatment. Here the form of a2(τ^/μ) is presented. Knowledge of a2 allows the new mass-loss formula of paper I to be applied, giving a calculation of the mass of the (assumed) final Schwarzschild black hole. Since the ``final mass'' resulting from the calculation exceeds 2μ, the assumptions of the new mass-loss formula must not all hold. The most likely explanation is that there is a ``second burst'' of radiation present in the space-time, centered for small angles θ^ on retarded times roughly ||8μ lnθ^|| later than the ``first burst'' described above. A more realistic crude estimate of the energy emitted in gravitational waves is given by the Bondi expression, taking only the first two terms a0 and a2 in c0; this gives an efficiency of 16.4% for gravitational wave generation.
