Similarity accounts of counterfactuals: A reality check1
Philosophy and Phenomenological Research, Volume 110, Issue 3, Page 887-915, May 2025.Abstract To an unusual extent, philosophers agree that counterfactuals have truth conditions involving the most similar possible worlds where their antecedents are true, in the style of the celebrated and path‐breaking Stalnaker/Lewis accounts. Roughly, these accounts say that the counterfactual if A were the case, C would be the case is true if and ...

A Non-Polynomial Gravity Formulation for Loop Quantum Cosmology Bounce
Galaxies, 2017 Recently the so-called mimetic gravity approach has been used to obtain corrections to the Friedmann equation of General Relativity similar to the ones present in loop quantum cosmology.

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

, 2014 We present a pedagogical introduction to the notions underlying the connection formulation of General Relativity - Loop Quantum Gravity (LQG) - with an emphasis on the physical aspects of the framework.

Enemies: uneasy accompaniments in late life Ennemis : accompagnements de fin de vie difficiles
Journal of the Royal Anthropological Institute, Volume 31, Issue S1, Page 128-144, April 2025.Against a phenomenological orientation to ageing as path or course, a contrastive frame is offered around a figure termed the enemy. Four distinctive ethnographic fragments are utilized: (1) a Polish‐Jewish migrant to Canada in her late eighties who listens continually to the radio and worries over the malign forces in the world that the radio ...

Primordial power spectrum from the Dapor–Liegener model of loop quantum cosmology [PDF]
General Relativity and Gravitation, 2018 We compute the predictions for the power spectrum of scalar perturbations from a recent new proposal for the effective Hamiltonian of loop quantum cosmology.

Place as a Metaphysical Problem in Albert the Great and Thomas Aquinas
Modern Theology, Volume 41, Issue 2, Page 292-310, April 2025.Abstract Thomas Aquinas’ particular synthesis of Aristotelianism and Neoplatonism, and the intellectual tradition it inaugurated, has at least twice faced critical challenges from developments in physics. Besieged by the sixteenth and seventeenth century novatores and more or less ignored by the nineteenth‐ and twentieth‐century practitioners of ...

Living Reviews in Relativity, 2004 The observable universe could be a 1+3-surface (the "brane") embedded in a 1+3+$d$-dimensional spacetime (the "bulk"), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

DeWitt boundary condition is consistent in Hořava-Lifshitz quantum gravity
Physics Letters B, 2022 In quantum cosmology the DeWitt boundary condition is a proposal to set the wave function of the universe to vanish at the classical big-bang singularity.

Stellar Physics and General Relativity
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...
