gravitational field quantization

Gravitational field quantization is the process of applying quantum mechanics to gravity, treating it as composed of tiny, discrete units called gravitons, similar to how electromagnetic fields are carried by photons. This approach seeks to unify general relativity, which describes gravity as spacetime curvature, with quantum theory, which describes subatomic particles. Although we have successfully quantized other forces, gravity remains challenging due to its weakness and the universe's extreme conditions. The goal is to develop a consistent theory that explains gravity at the smallest scales, potentially revealing new fundamental insights about the nature of the universe.
