Quantum gravitational effects suppress the formation of trapped surfaces

Ram Brustein, A. J. M. Medved, Hagar Meir

Classical general relativity predicts that a contracting, spherically symmetric matter system with a large-enough mass will result in the formation of a trapped region whose outer…

Hierarchical constraints on gravitational waves from horizonless compact objects

Rajrupa Mondal, Julian Westerweck, Yotam Sherf +2

We use the data of several promising gravitational wave observations to obtain increasingly stringent bounds on near-horizon deviations of their sources from the Kerr geometry. A r…

Black hole mimickers: from theory to observation

Cosimo Bambi, Ramy Brustein, Vitor Cardoso +16

The black hole paradigm, while remarkably successful, raises fundamental questions-both classical and quantum-about the nature of spacetime, horizons, and singularities. Black hole…

Origin of the blackhole information paradox

Ram Brustein

It is argued that the blackhole information paradox originates from treating the blackhole geometry as strictly classical. It is further argued that the theory of quantum fields in…

Limitations in using luminosity distance to determine the equation of state of the universe

Irit Maor, Ram Brustein, Paul J. Steinhardt

Supernova searches have been been suggested as a method for determining precisely the current value and time variation of the equation of state, , of the dark energy component r…

Duality in cosmological perturbation theory

R. Brustein, M. Gasperini, G. Veneziano

Cosmological perturbation equations derived from low-energy effective actions are shown to be invariant under a duality transformation reminiscent of electric-magnetic, strong-weak…
