A time varying speed of light as a solution to cosmological puzzles [PDF]

, 1999
We consider the cosmological implications of light travelling faster in the early Universe. We propose a prescription for deriving corrections to the cosmological evolution equations while the speed of light $c$ is changing. We then show how the horizon,

Introduction: Beyond public reason Introduction : Par‐delà la raison publique

Journal of the Royal Anthropological Institute, EarlyView.
This introduction situates the special issue within longstanding debates on liberal public reason, tracing its Enlightenment roots through Habermas and Rawls to contemporary political dilemmas. It highlights how anthropology has revealed the exclusions embedded in public reason's universalist claims, particularly for those marginalized by culture, race,

Brane cosmology, Weyl fluid, and density perturbations [PDF]

, 2008
We develop a technique to study relativistic perturbations in the generalised brane cosmological scenario, which is a generalisation of the multi-fluid cosmological perturbations to brane cosmology. The novelty of the technique lies in the inclusion of a

Relativistic Hydrodynamic Cosmological Perturbations [PDF]

, 1999
Relativistic cosmological perturbation analyses can be made based on several different fundamental gauge conditions. In the pressureless limit the variables in certain gauge conditions show the correct Newtonian behaviors.

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War

Anthropology of Consciousness, EarlyView.
ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Cosmological perturbations from five-dimensional inflation

Journal of High Energy Physics
It was recently proposed that five-dimensional inflation can relate the causal size of the observable universe to the present weakness of gravitational interactions by blowing up an extra compact dimension from the microscopic fundamental length of ...

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Cosmological influence of super-Hubble perturbations

, 2005
The existence of cosmological perturbations of wavelength larger than the Hubble radius is a generic prediction of the inflationary paradigm. We provide the derivation beyond perturbation theory of a conserved quantity which generalizes the linear ...

Rotational Perturbations of Friedmann-Robertson-Walker Type Brane-World Cosmological Models [PDF]

, 2002
First order rotational perturbations of the Friedmann-Robertson-Walker metric are considered in the framework of the brane-world cosmological models.
