Gravity is a fundamental force in the universe, and it is one of the four fundamental forces in nature, alongside the strong nuclear force, the weak nuclear force, and electromagnetism. The basic concept of gravity, as you stated, is that it is a force that exists between two objects with mass and causes them to attract each other. This force is proportional to the masses of the objects and inversely proportional to the square of the distance between them.

While the basic concept of gravity is relatively simple, the full understanding of gravity can be quite complex. For example, the general theory of relativity, which provides a mathematical framework for understanding gravity as a curvature of spacetime, is a highly complex and abstract theory. Additionally, the search for gravitons, the hypothetical particles that are believed to carry the gravitational force, is an ongoing area of research in theoretical physics.

Overall, while the basic concept of gravity is relatively straightforward, the full understanding of gravity can be complex and abstract, requiring an understanding of advanced mathematical concepts and physical theories.
