COSMOLOGY AND LOCAL PHYSICS [PDF]

open access: yesInternational Journal of Modern Physics A, 2002
This article considers the two-way relationship between local physics and the large scale structure of the universe - in particular considering Olber's paradox, Mach's principle, and the various arrows of time. Thus the focus is various ways in which local physics is influenced by the universe itself.

Particle physics and cosmology [PDF]

open access: yesGeneral Relativity and Gravitation, 1995
ABSTRACTThe agreement between the observed light element abundances and calculations of homogeneous cosmological nucleosynthesis constrains inhomogenequs models, and suggests that most of the matter in the Universe is invisible Dark Matter. This could be in the form of neutrinos, lightest supersymmetric particles (LSPs) or axions.

Anomalies in Physical Cosmology

open access: yesAnnals of Physics, 2022
The ΛCDM cosmology passes demanding tests that establish it as a good approximation to reality. The theory is incomplete, of course, and open issues are being examined in research programs that promise to improve the cosmological tests and perhaps yield hints to a still better theory. But there is the possibility that less widely discussed observations,

COSMOLOGICAL TERM AND FUNDAMENTAL PHYSICS [PDF]

open access: yesInternational Journal of Modern Physics D, 2004
A nonvanishing cosmological term in Einstein's equations implies a nonvanishing spacetime curvature even in the absence of any kind of matter. It would, in consequence, affect many of the underlying kinematic tenets of physical theory. The usual commutative spacetime translations of the Poincaré group would be replaced by the mixed conformal ...

Laboratory Physics and Cosmology. [PDF]

open access: yesPhysics Essays, 2004
We find five fundamental reasons demanding that any gravitational mass m, and the speed of light c, vary with cosmological time such that mc remains constant. This is required by the universal condition of conservation of momentum in a Universe with spatial homogeneity. We prove that this is consistent with Einstein's Theory of General Relativity.

LHC PHYSICS AND COSMOLOGY [PDF]

open access: yesFundamental Interactions, 2007
In these Lectures I review possible constraints on particle physics models, obtained by means of combining the results of collider measurements with astrophysical data. I emphasize the theoretical-model dependence of these results. I discuss supersymmetric dark matter constraints at colliders (mainly LHC) in various theoretical contexts: the standard ...

Collider physics and cosmology [PDF]

open access: yesClassical and Quantum Gravity, 2008
In the coming year, the Large Hadron Collider will begin colliding protons at energies nearly an order of magnitude beyond the current frontier. The LHC will, of course, provide unprecedented opportunities to discover new particle physics. Less well-known, however, is that the LHC may also provide insights about gravity and the early universe. I review

Cosmology and new physics [PDF]

open access: yesPhysics of Atomic Nuclei, 2008
A comparison of the standard models in particle physics and in cosmology demonstrates that they are not compatible, though both are well established. Basics of modern cosmology are briefly reviewed. It is argued that the measurements of the main cosmological parameters are achieved through many independent physical phenomena and this minimizes possible

Physical and Relativistic Numerical Cosmology [PDF]

open access: yesLiving Reviews in Relativity, 1998
In order to account for the observable Universe, any comprehensive theory or model of cosmology must draw from many disciplines of physics, including gauge theories of strong and weak interactions, the hydrodynamics and microphysics of baryonic matter, electromagnetic fields, and spacetime curvature, for example. Although it is difficult to incorporate
