Wide Energy Spectrum of Gravitation: The General Theory and Beyond

The mere fact that GR confirms that (non-gravitational) laws of physics may take on their SR forms locally at a point, where a Lorentz frame is set, means that it may handle high energy particles. As a matter of fact, energy considerations of high-energetic particles necessitate to modify Newton’s theory of gravitation, due to its underlying action at-a-distance, and gives rise to Einstein’s GR. After developing the GR theory, in its entirety, from scratch, we consider its consequences and witness how it stood the test of time and spell out the intricacies of black holes, white holes and wormholes. High energy considerations of GR, in a perturbative QFT setting, show that the degree of divergence of transition amplitudes increases, with higher orders, with no bound, implying the underlying theory fails to satisfy the criterion of renormalizability met by our other theories. In a non-perturbative background independent formulation of gravitation, considerations of a high-energy probe to explore the space structure at distances beyond the Planck length, seem to convey the quantization of area in units of the Planck length squared and describes space as composed of a network of loops woven together with nothing else in between.
