Black holes turn white fast, otherwise stay black: no half measures
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay
Recently, various authors have proposed that the first ultraviolet effect on the gravitational collapse of massive stars to black holes is the transition between a black-hole geome…
Where does the physics of extreme gravitational collapse reside?
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay
The gravitational collapse of massive stars serves to manifest the most severe deviations of general relativity with respect to Newtonian gravity: the formation of horizons and spa…
Uncovering the effective spacetime: Lessons from the effective field theory rationale
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay
The cosmological constant problem can be understood as the failure of the decoupling principle behind effective field theory, so that some quantities in the low-energy theory are e…
Some not-so-common ideas about gravity
Raúl Carballo-Rubio, Carlos Barceló, Luis J. Garay
Most of the approaches to the construction of a theory of quantum gravity share some principles which do not have specific experimental support up to date. Two of these principles…
Longitudinal diffeomorphisms obstruct the protection of vacuum energy
Raúl Carballo-Rubio
To guarantee the stability of the cosmological constant sector against radiative corrections coming from quantum matter fields, one of the most natural ingredients to invoke is the…
