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

The professor why we wanted to quantize gravity, in the sense that we want to treat the metric on space-time as a quantum field, as opposed to, for example, just leaving the metric alone, and doing quantum field theory in curved space-time. The Skyrmion as a fermi field enters the picture when this potential energy portion has Bogoliubov coefficients, which both define quantum field in curved spacetime and superconductivity. He highlighted how gravitational force is replaced by a curving of space-time in Einstein's theory of General Relativity. A very thin rubber sheet is a pretty good . Perhaps suggesting a less dense area in space say nearer the center of a galaxy v/s the extreme perimeter light could travel faster or slower until it comes to the field we know and love here called Constants. This curvature is very small, and its effects are hardly noticable in everyday life and over small distances. "The various developments of quantum field theory in curved space-time have left the false impression that general relativity and quantum mechanics are compatible. Well, the issue is that professor Wisdom's 'breaststroke' is not particularly effective to overcome earth's gravity, as it relies on the local curvature of spacetime. Relativity tells us that spacetime is curved, and that curvature causes the force of gravity. The three microscopic forces arise from force-carrying particles in Quantum Field Theory. A recent study of gamma-ray bursts finds that spacetime is smoother on the quantum scale than expected. Or indeed the Quantum Field, Higgs Field, New Luminiferous Ether, or whatever else we may end up calling it.
