Gravity Duals

Gravity duals are relationships in theoretical physics where a complex quantum system without gravity can be represented by a higher-dimensional gravitational theory. Think of it as two different descriptions of the same phenomena: one involving particles and forces without gravity, and the other involving a curved spacetime with gravity. This duality allows scientists to study difficult problems in quantum physics by instead examining the more manageable gravitational model. It’s a powerful tool in understanding phenomena like black holes, high-temperature superconductors, and the behavior of strongly interacting particles.
