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. Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. The prediction of their existence falls out of the Dirac Equation, but Einstein's model accounts for the negative energy states differently than modern quantum field theory does: Once Upon a Spacetime · 3:58 PM. Quantum Wave Theory proposes a new model of space. 1:29 And All said, Behold, we rule the quantum field, which is upon the face of all the universe, and every piece of space and time, yet we fail to understand how the quantum bends space and time. Even a “perfect” vacuum would still hold vacuum energy, the Higgs field, and spacetime curvature. Since there is no complete quantum theory of gravity, they used an established approach called quantum field theory in curved spacetime (QFTCS). Red oval (1/c = 0, vanishing slowness of light): theories ignoring relativistic effects, blue circle (h = 0, vanishing quanta): theories ignoring quantum effects, green circle (G = 0, vanishing gravity): theories ignoring spacetime curvature. The theory describes space as a continuous, quantized, flexible 'field;' nowhere divided or divisible, but capable of discrete motions of compression and rebound. He highlighted how gravitational force is replaced by a curving of space-time in Einstein's theory of General Relativity. Einstein's proposed unified-field equations (fundamental laws of physics) were generally derived from a variational principle expressed in terms of the Riemann curvature tensor for the presumed space-time manifold. 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.

Outer space is teaming with fields and particles. [2][3] Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. The three microscopic forces arise from force-carrying particles in Quantum Field Theory. In field theories of this kind, particles . In loop quantum gravity, the four dimensions of spacetime are composed of networks of intersecting loops — ripples of the gravitational field.
