John Donoghue: The Physicist Who Says We've Already Quantized Gravity
John Donoghue, a theoretical physicist known for work on quantum gravity and effective field theory, argues gravity can be quantized like other fields. He discusses quadratic gravity, effective field theory, and how higher-derivative terms affect causality and singularities. He also challenges assumptions about unification, naturalness, and offers the idea of random dynamics shaping low-energy laws.
