Lorentz invariance with an invariant energy scale
Joao Magueijo, Lee Smolin
We propose a modification of special relativity in which a physical energy, which may be the Planck energy, joins the speed of light as an invariant, in spite of a complete relativ…
A thermal instability for positive brane cosmological constant in the Randall-Sundrum cosmologies
Stephon Alexander, Yi Ling, Lee Smolin
We describe a novel dynamical mechanism to radiate away a positive four dimensional cosmological constant, in the Randall-Sundrum cosmological scenario. We show that there are mode…
The Maldacena Conjecture and Rehren Duality
Matthias Arnsdorf, Lee Smolin
We analyse the implications of the fact that there are two claims for a dual to \N=4 superconformal SU(N) Yang-Mills theory (SCYM), the Maldacena conjecture and the theorem of Rehr…
The present moment in quantum cosmology: challenges to the arguments for the elimination of time
Lee Smolin
Barbour, Hawking, Misner and others have argued that time cannot play an essential role in the formulation of a quantum theory of cosmology. Here we present three challenges to the…
The exceptional Jordan algebra and the matrix string
Lee Smolin
A new matrix model is described, based on the exceptional Jordan algebra. The action is cubic, as in matrix Chern-Simons theory. We describe a compactification that, we argue, repr…
