Gauge/gravity duality

Gauge/gravity duality is a theoretical idea suggesting that certain quantum field theories (describing particles and forces) have equivalent descriptions in terms of gravity in a higher-dimensional space. Imagine a complex, dynamic system—like a web of interconnected particles—being perfectly represented by a gravitational universe with an extra dimension. This duality allows scientists to study difficult quantum problems using classical gravity models, and vice versa, providing a powerful bridge between two seemingly different realms of physics for better understanding of the universe’s fundamental laws.
