George F. R. Ellis
I consider the relation of explanations for the observed data to testability in the following contexts: observational and experimental detection of dark matter; observational and e…
Time drift of cosmological redshifts as a test of the Copernican principle
Jean-Philippe Uzan, Chris Clarkson, George F. R. Ellis
We present the time drift of the cosmological redshift in a general spherically symmetric spacetime. We demonstrate that its observation would allow us to test the Copernican princ…
Note on Varying Speed of Light Cosmologies
George F R Ellis
The various requirements on a consistent varying speed of light (`VSL') theory are surveyed, giving a short check-list of issues that should be satisfactorily handled by such theor…
Issues in the Philosophy of Cosmology
George F. R. Ellis
After a survey of the present state of cosmological theory and observations, this article discusses a series of major themes underlying the relation of philosophy to cosmology. The…
On horizons and the cosmic landscape
George F R Ellis
Susskind claims in his recent book The Cosmic Landscape that evidence for the existence and nature of `pocket universes' in a multiverse would be available in the detailed nature o…
An emergent universe from a loop
David J. Mulryne, Reza Tavakol, James E. Lidsey +1
Closed, singularity-free, inflationary cosmological models have recently been studied in the context of general relativity. Despite their appeal, these so called emergent models su…
