The definition of a quantum theory for gravity is a long standing problem. Currently, different approaches exist. In this talk, I will present the main ideas behind Loop Quantum Gravity and the Spinfoam frameworks. These are attempts to quantize directly General Relativity using respectively Dirac’s canonical quantization and Feynman’s path integral quantization.
I will give an overview of...

Recent implications of results from quantum information theory applied
to black holes has led to the confusing conclusions that requires
either abandoning the equivalence principle (e.g. the firewall
picture), or the no-hair theorem (e.g. the fuzzball picture), or even
more unpalatable options.
The recent discovery of a pulsar orbiting a black hole opens up new
possibilities for tests...

The cornerstone of thermodynamics is the first law, which for a black hole
identifies thermodynamic energy with its mass, temperature with its surface
gravity, and entropy with its area. Recent work that posits the
identification of a cosmological constant with thermodynamic pressure results
in black holes behaving somewhat like chemical systems, with pressure-volume
terms appearing in...

We formulate quantum field theory in accelerated frames using Prigogine transformations. We then derive a background independent formulation of such transforms, and attempt a new formulation of quantum gravity.
