Quantum Physics, Quantum Mechanics, General RelativityAbstract
Quantum mechanics and general relativity, two of the most important branches of science explaining our world, are contradictory in nature. The search for a Grand Unified Theory of the universe that would be able to link these two branches so far with concrete foundations has been to no avail. So far, general relativity has successfully been able to describe the movement of planets and stars. Quantum physics describes the physics of the subatomic world. Unfortunately, gravity currently has no concrete basis in quantum theory; the most prevalent theories describing human understanding of the universe are incompatible. Using various research papers and articles, this paper reviews the different theories addressing the gap in our understanding, such as String Theory and Loop Quantum Gravity, and why they may fit with our expectations, as well as what shortcomings they have. By discovering a bridge between quantum physics and gravity, we would have a more complete general understanding of the mechanics of our universe. This review paper is aimed at helping to understand the development of the theory of quantum gravity and the various candidates for the Grand Unified Theory.
