the universe are examined. In Chapter 1 it is shown that this
expansion creates grave difficulties for the Hoyle-Narlikar theory
of gravitation. Chapter 2 deals with perturbations of an expanding
homogeneous and isotropic universe. The conclusion is reached that
galaxies cannot be formed as a result of the growth of perturbations
that were initially small. The propagation and absorption of
gravitational radiation is also investigated in this approximation.
In Chapter 3 gravitational radiation in an expanding universe is
examined by a method of asymptotic expansions. The 'peeling off'
behaviour and the asymptotic group are derived. Chapter 4 deals with
the occurrence of singularities in cosmological models. It is shown
that a singularity is inevitable provided that certain very general
conditions are satisfied.Properties of expanding universes / Stephen HawkingEnglishHawking, Stephen, 1942-AbstractIntroductionAcknowledgementsChapter 1: The Hoyle-Narlikar theory of gravitationChapter 2: PerturbationsChapter 3: Gravitational radiation in an expanding
