Quantum Gravity- Gravitons

Quantum gravity aims to unify quantum mechanics, which governs small-scale particle behavior, and general relativity, which describes gravity and spacetime on a cosmic scale. Key approaches include string theory, where the universe's basic elements are tiny, vibrating strings, and loop quantum gravity, which proposes that spacetime consists of discrete loops. These theories seek to resolve cosmic singularities and offer new insights into the universe, potentially revolutionizing our understanding by creating a unified framework that bridges the microscopic and macroscopic realms.
