Thermodynamics in space-times without horizons
Raymond Isichei, João Magueijo
We consider the energetics and thermodynamics of spacetimes with no horizons, but endowed with a preferred timelike junction surface. They could arise as a limiting case of the gra…
Attracting without being attracted: Dark Matter as an aether wind
Raymond Isichei, Joao Magueijo
We explore the possibility that part of what we call dark matter may be the mark of a preferred frame, revealing a breakdown of diffeomorphism invariance. In the non-relativistic l…
How to make a Universe
Paolo M Bassani, Joao Magueijo
We establish the general conditions under which evolution in the laws of physics and matter creation or destruction are closely intertwined. They make use of global time variables…
Quantum wormholes at spatial infinity
João Magueijo, Ganga Singh Manchanda
We derive the interesting result that the two asymptotically flat Universes classically linked by the Einstein-Rosen bridge may also be quantum mechanically connected in their far…
Dark matter and space-time symmetry restoration
Joao Magueijo
We examine local physics in the presence of global variables: variables associated with the whole of the spacelike surfaces of a foliation. These could be the (pseudo-)constants of…
