Quantum Fields in Curved Space N. D. Birrell, P. C. W. Davies
Publisher: Cambridge University Press

Know that the above stuff converges properly to something which makes sense. The Field Equations control the curvature of space-time and represent our theory of gravity, while the Yang-Mills and Dirac equations represent the theory of particle interactions on a quantum level. €�Measuring the curvature of space caused by gravity is one of the most sensitive ways to learn how Einstein's theory of General Relativity relates to quantum physics. For light scalar fields, perturbation theory is plagued by infrared divergences which require resummation techniques. Excitations of the gravitation field give rise to the notion of length, are and volume ie.. Uniting gravity theory with quantum theory is a major goal of 21st-Century physics, .

In loop quantum gravity, the four dimensions of spacetime are composed of networks of intersecting loops — ripples of the gravitational field. The researchers applied loop quantum gravity theory to the simplest model of Pullin emphasized that they used a very simple model in this study, consisting of only highly curved spacetime without representing the actual matter found inside real black holes. Its also in the lecture series he gave, “Quantum FIeld Theory in Curved Spacetime and Black Hole Thermodyanmics”.
