What exactly is 2D quantum gravity? Is it just a simplification of 3D quantum gravity i.e. to get results easier?

2D quantum gravity is a theoretical framework that attempts to describe the behavior of gravity at the quantum level in two dimensions. It is a simplified model used to study the effects of quantum mechanics on gravity, and it does not fully reflect the complexities of our three-dimensional world.
Classical gravity, as described by Newton's law of gravitation, is a force that acts between two massive objects. 2D quantum gravity, on the other hand, considers gravity as a quantum field that is affected by the principles of quantum mechanics. This means that at the quantum level, gravity may behave differently than what is predicted by classical physics.
One of the main challenges in studying 2D quantum gravity is that it is a highly theoretical concept that is difficult to experimentally test. Another challenge is that it involves complex mathematical calculations and requires expertise in both quantum mechanics and general relativity.
2D quantum gravity is often studied as a potential step towards finding a theory of everything, which would unify all the fundamental forces of nature. By studying how gravity behaves at the quantum level, scientists hope to gain a better understanding of how it fits into the larger picture of the universe.
While 2D quantum gravity is primarily a theoretical concept, it has potential applications in fields such as cosmology, where it could help explain the behavior of the early universe. It may also have implications for understanding black holes and their behavior at the quantum level.
