The Cosmology of an Infinite Dimensional Universe
David Sloan, Pedro Ferreira
We consider a universe with an arbitrary number of extra dimensions, . We present a new method for constructing the cosmological equations of motion and find analytic solutions…
Measures in Mutlifield Inflation
Richard Grumitt, David Sloan
We examine the classical dynamics of multifield inflation models with quadratic potentials. Such models are shown to have inflationary attractors in phase space, consistent with th…
Relative Likelihood for Life as a Function of Cosmic Time
Abraham Loeb, Rafael A. Batista, David Sloan
Is life most likely to emerge at the present cosmic time near a star like the Sun? We address this question by calculating the relative formation probability per unit time of habit…
Through the Big Bang
Tim A Koslowski, Flavio Mercati, David Sloan
All measurements are comparisons. The only physically accessible degrees of freedom (DOFs) are dimensionless ratios. The objective description of the universe as a whole thus predi…
as an Attractor
David Sloan
It has recently been shown, in flat Robertson-Walker geometries, that the dynamics of gravitational actions which are minimally coupled to matter fields leads to the appearance of…
Anisotropic Matter in Cosmology: Locally Rotationally Symmetric Bianchi and Models
David Sloan
We examine the behaviour of homogeneous, anisotropic space-times, specifically the locally rotationally symmetric Bianchi types and in the presence of anisotropic matte…
