Late-time effects of Planck-scale cosmology: dilatonic interpretation of the dark energy field

open access: yes, 2003
We present a model of dark energy based on the string effective action, and on the assumption that the dilaton is strongly coupled to dark matter. We discuss the main differences between this class of models and more conventional models of quintessence ...

Da maçã de Eva à maçã de Newton [PDF]

open access: yes, 2017
Este trabalho tem como objetivo demonstrar como o aristotelismo foi reconstruído a partir do século XIII por Santo Tomás de Aquino para dar respaldo racional e filosófico à teologia católica e como a física e a cosmologia aristotélicas foram, no decorrer

Scale-dependent and background-preserving gravity from an action: cosmological tests

open access: yesEuropean Physical Journal C: Particles and Fields
We investigate the observational implications of a gravitational model wherein the gravitational constant G and the cosmological constant $$\Lambda $$ Λ exhibit scale-dependent behavior at the perturbative level, while preserving the General Relativity ...

O PRINCÍPIO DA CIÊNCIA:

open access: yesPolymatheia, 2021
Neste breve artigo tratamos da origem da atitude científica entre os filósofos gregos antigos, conhecidos como pré-socráticos. Nossa vindicação é de que tais filósofos instauraram os pressupostos filosóficos básicos do pensamento científico.

Emilie du Chatelet's Metaphysics of Substance [PDF]

open access: yes, 2018
much early modern metaphysics grew with an eye to the new science of its time, but few figures took it as seriously as Emilie du Châtelet. Happily, her oeuvre is now attracting close, renewed attention, and so the time is ripe for looking into her ...

A supersymmetric black ring [PDF]

open access: yes, 2004
A new supersymmetric black hole solution of five-dimensional supergravity is presented. It has an event horizon of topology S1xS2. This is the first example of a supersymmetric, asymptotically flat black hole of non-spherical topology.

Restoring Lorentz symmetries in parity-even Einstein–Cartan domain walls conformal to Bianchi I metric embedded in weak gravity Weitzenböck vacuum manifold

open access: yesEuropean Physical Journal C: Particles and Fields
It is well known that a weak gravity limit can be associated with a restoration of Lorentz covariance. In this paper we present a physical example of a parity-even Einstein–Cartan domain wall (ECDW) embedded in a Weitzenböck zero connection vacuum ...

¿Cómo construir cuerpos individuales en el universo cartesiano?

open access: yesAnales del Seminario de Historia de la Filosofía, 2016
En el presente artículo se muestra que en la cosmología cartesiana no resulta claro cómo se puede hablar o referir a cuerpos individuales en el marco de un universo absolutamente compacto.
