Emergence of time in Loop Quantum Gravity As long as one uses a quantization scheme which re-spects covariance, holonomy corrections from loop quantum gravity generically leads to non-singular signature change, thereby giving an emergent notion of time in the theory
Loop quantum gravity: overview and recent developments Using these structures, Thomas Thiemann was able in 1996 to write the first non-trivial, mathematically well defined, finite, anomaly free theory of quantum gravity (including coupling to matter)
Loop Quantum Gravity (LQG): A Discrete Structure of Spacetime Loop Quantum Gravity (LQG) is a leading approach to quantum gravity that attempts to reconcile general relativity (gravity as spacetime curvature) with quantum mechanics (discrete, quantized physics)
Time in quantum gravity. | PIRSA I will briefly review the different notions of time in classical and quantum mechanics and then focus on explaining the fundamental clash that exists between the notions of time in Quantum Field theory and general relativity
6 - Space and Time in Loop Quantum Gravity Published online by Cambridge University Press: 24 April 2020 Quantum gravity is expected to require modifications of the notions of space and time I discuss and clarify how this happens in loop quantum gravity
