Universal problems
Speaker(s): David Mattingly
Abstract: Arguments that gravity cannot be a local renormalizable quantum field theory come from both field theory lore and black hole physics. Two current approaches to quantum gravity, asymptotic safety and Horava-Lifshitz gravity, both of which treat quantum gravity as a local renormalizable QFT, are expli... read more

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

Quantum Gravity Effects in Black Holes and Gravitational Waves
Abstract: Quantum-gravity effects as noise for gravity-wave detectorsI discuss a mechanism that can allow Planck scale effects to manifest themselves as a source of lof-frequency noise for interferometers.  The mechanism requires a discrete formulation of dynamics at the Planck scale._______________... read more
