Quantum Spacetime in the Sky: From Horizon to Horizon

Explore the fascinating realm of quantum spacetime fluctuations and their impact on gravitational wave observations in this comprehensive lecture. Delve into three key aspects: quantum fluctuations near black hole horizons leading to Hawking emission and Kerr geometry deformation, irreducible noise in gravitational wave detectors caused by spacetime geometry fluctuations, and the potential for a "cosmic glitch" in gravity near the cosmological horizon. Gain insights into the theoretical and observational evidence supporting these phenomena, and understand their significance as manifestations of UV/IR coupling in non-perturbative quantum gravity theories. This in-depth presentation offers a unique perspective on the intersection of quantum mechanics and cosmology, providing valuable knowledge for researchers and enthusiasts in the field of gravitational physics.
