Evolution of Black Holes in Brans-Dicke Cosmology
Nobuyuki Sakai, John D. Barrow
We consider a modified ``Swiss cheese'' model in the Brans-Dicke theory, and discuss the evolution of black holes in the expanding universe. We define the black hole radius by the…
The Isotropy of Compact Universes
John D. Barrow, Hideo Kodama
We discuss the problem of the stability of the isotropy of the universe in the space of ever-expanding spatially homogeneous universes with a compact spatial topology. The anisotro…
Further Evidence for Cosmological Evolution of the Fine Structure Constant
J. K. Webb, M. T. Murphy, V. V. Flambaum +5
We describe the results of a search for time variability of the fine structure constant, alpha, using absorption systems in the spectra of distant quasars. Three large optical data…
Possible evidence for a variable fine structure constant from QSO absorption lines: motivations, analysis and results
M. T. Murphy, J. K. Webb, V. V. Flambaum +5
An experimental search for variation in the fundamental coupling constants is strongly motivated by modern high-energy physics theories. Comparison of quasar absorption line spectr…
Can the Universe escape eternal acceleration?
John Barrow, Rachel Bean, Joao Magueijo
Recent astronomical observations of distant supernovae light-curves suggest that the expansion of the universe has recently begun to accelerate. Acceleration is created by an anti-…
