Its hard to describe the frustration and anger I feel to see all these papers talk about “tensor networks” and geometry as if they are discovering something new which wasn’t already discovered 31 years ago under the framework known as Loop Quantum Gravity (LQG). Take this recent paper for example: http://arxiv.org/abs/2402.05910 “First, how might we… Continue reading The “Rediscovery” of Spin Networks and Loop Quantum Gravity
