The infinite turn and speculative explanations in cosmology

Reza Tavakol, Fabio Gironi

Infinity, in various guises, has been invoked recently in order to `explain' a number of important questions regarding observable phenomena in science, and in particular in cosmolo…

We have time because we shall never know

Reza Tavakol, Edward Anderson

We argue against current proposals concerning the non-existence of time. We point out that a large number of these proposals rely, at least implicitly, on the assumption of `closur…

Exact Evolution of Discrete Relativistic Cosmological Models

Timothy Clifton, Daniele Gregoris, Kjell Rosquist +1

We study the effects of inhomogeneities on the evolution of the Universe, by considering a range of cosmological models with discretized matter content. This is done using exact an…

What Planck does not tell us about inflation

Joseph Elliston, David J. Mulryne, Reza Tavakol

Planck data has not found the 'smoking gun' of non-Gaussianity that would have necessitated consideration of inflationary models beyond the simplest canonical single field scenario…

A Gravitational Entropy Proposal

Timothy Clifton, George F R Ellis, Reza Tavakol

We propose a thermodynamically motivated measure of gravitational entropy based on the Bel-Robinson tensor, which has a natural interpretation as the effective super-energy-momentu…

The inflationary bispectrum with curved field-space

Joseph Elliston, David Seery, Reza Tavakol

We compute the covariant three-point function near horizon-crossing for a system of slowly-rolling scalar fields during an inflationary epoch, allowing for an arbitrary field-space…
