as I know, they both explain about how gravitation work.
But how they different? which one is the most correct?

General relativity is a theory of gravity that describes how massive objects interact with each other and with space-time. It was developed by Albert Einstein in the early 20th century. Quantum gravity, on the other hand, is a theoretical framework that aims to unite general relativity with quantum mechanics, which describes the behavior of particles on a very small scale.
The main difference between general relativity and quantum gravity is their approach to understanding the fundamental forces of the universe. General relativity explains gravity as the curvature of space-time, while quantum gravity attempts to explain gravity as a quantum force carried by particles called gravitons.
Understanding the difference between general relativity and quantum gravity is important because it can help us develop a more complete understanding of the universe. General relativity is successful in explaining the behavior of large-scale objects, while quantum mechanics is successful in explaining the behavior of small-scale particles. By combining these two theories, we can potentially unlock new insights into the fundamental laws of the universe.
One of the main challenges in reconciling general relativity and quantum gravity is that they use different mathematical frameworks. General relativity uses smooth, continuous equations to describe the behavior of space and time, while quantum mechanics uses discrete, probabilistic equations to describe the behavior of particles. This creates a fundamental incompatibility between the two theories.
Currently, there is no single theory that can fully explain both general relativity and quantum gravity. Many scientists are working on various approaches and theories, such as string theory and loop quantum gravity, in an attempt to reconcile these two fundamental theories. However, the search for a unified theory is ongoing and the ultimate answer may still be unknown.
