Threads, Quanta, and Technostuff: Theory of Loop Quantum Gravity

Thread, quantum and techno staff cycle The quantum gravity theory is the only effective competition for super string theory. This theory quantifies Einstein 's theory of relativity by decomposing space and time into plank - scale parts called quantum. The Planck scale, named after Max Planck, is the absolute minimum microscope measurement in the space-time structure physicists have always dreamed about. At this level there are very large and very small collisions in the so-called quantum gravity.

Another general theory is ring quantum gravity (LQG), the first theory advocated by Carlo Rovelli, which explains the quantum nature of gravity. In general relativity, spatiotemporal geometry is the expression of gravity, so it is also the theory of quantum space and quantum time. LQG attempts to integrate and tune standard quantum mechanics and standard general relativity. The main output of this theory is the physical image of the space where the space is granular. Grain size is a direct result of quantification. It has the same properties as photon grain size or discrete energy level of atomic energy in electromagnetic quantum theory. But here space itself is discrete. Rather, the space can be viewed as a very finite finite cycle of "weaving" of the fabric or network. These cyclic networks are called spin networks. The evolution of the rotating network over time is called the rotating form. Planck scale energy)

The main result of ring quantum gravity is the derivation of the granular spatial structure over the Planck length. This arises from the consideration that in the case of electromagnetics, the quantum operator representing the energy of each frequency of the field has a discrete spectrum. Therefore, the energy of each frequency is quantized and the quantum is photon. In the case of gravity, the operator representing the area and volume of each surface or spatial region also has a discrete spectrum. Therefore, the area and volume of any part of the space is also quantified. Here, quantum is the fundamental quantum of space. It is concluded that the space and time have the fundamental quantum particle structure of Planck scale and hence blocks UV infinity of quantum field theory.
