A novel approach to diffusing the black hole information paradox
Speaker(s): Daniel Sudarsky
Abstract: We will briefly review the issue of "information loss" during the Hawking evaporation of a black hole, and argue that the quantum dynamical reduction theories, which have been developed to address the measurement problem in quantum mechanics, possess the elements to ... read more

PIRSA:15060005  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum fluctuations as the seeds of cosmic structure.
Speaker(s): Daniel Sudarsky
Abstract: Although the inflationary predictions for the primordial power spectrum of density inhomogeneities seem very successful, there is an obscure part in our understanding of the emergence of the seeds of cosmic structure: How does a universe which at one pint in time is described by a state... read more

PIRSA:12100108  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Lorentz symmetry: Broken, intact or deformed?
Abstract: Is aether technically natural?I will discuss whether higher energy Lorentz violation should be considered a natural expectation in theories of quantum gravity with a preferred frame._____________________________If spacetime is a causal set then Lorentz symmetry is unbroken___________________________... read more

PIRSA:12100090  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Quantum Gravity Effects in the (Early and Late) Universe
Abstract: Quantum Gravity at the origin of seeds of cosmic structure?This meeting shows a our impatience for uncovering at long last any signal of unknown physics that might have a quantum gravitational origin. I will argue that the transition from a homogenous and isotropic state characterizing the mid-earl... read more

PIRSA:12100127  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Improved test of the Equivalence Principle as a probe of quantum gravity
Abstract: Current approaches to the problems of dark energy and unification generically predict the existence of new fields (quintessence dilatons etc.) that will in principle couple with different strengths to different standard-model fields. These different coupling strengths will cause test materials of di... read more

PIRSA:07110040  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The quantum origin of the cosmological structure: an arena for quantum gravity phenomenology
Speaker(s): Daniel Sudarsky
Abstract: I will review the shortcomings of the standard account of the origin of anisotropies and in-homogeneities in inflationary cosmology. I will argue that something beyond the established paradigm of physics in needed for a satisfactory explanation of the process by which the seeds of structure emerge f... read more
