Inflation from R^2 gravity: a new approach using nonlinear electrodynamics
We discuss another approach regarding the inflation from the R^2 theory of gravity originally proposed by Starobinski. A non-singular early cosmology is proposed, where, adding a nonlinear electrodynamics Lagrangian to the high-order action, a bouncing ...

La cosmología evasiva de Ramon Llull [PDF]
Ramon Llull fou un autor prolífic que escrigué més de 240 obres sobre els temes més diversos, però el seu interès principal era apologètic. Així, la major part de les seves obres s’orienten a la demostració racional de principis religiosos mitjançant el ...

"What are mortals that you are mindful of them?" A Reading of the Biblical Message about Human Being and Nature from the New Vision of Science and Ecology [PDF]
The author integrates the new scientific view of the universe with a rereading of the Genesis creation narratives. He introduces a reading of the human being as Vicar of God in light of \"precomprehension\" offered by science and the ecological crisis ...

A black ring with a rotating 2-sphere
We present a solution of the vacuum Einstein's equations in five dimensions corresponding to a black ring with horizon topology S^1 x S^2 and rotation in the azimuthal direction of the S^2. This solution has a regular horizon up to a conical singularity,

A note on accelerating cosmologies from compactifications and S-branes
We give a simple interpretation of the recent solutions for cosmologies with a transient accelerating phase obtained from compactification in hyperbolic manifolds, or from S-brane solutions of string/M-theory.
