New techniques can answer questions that were previously inaccessible experimentally — including questions about the relationship between quantum mechanics and relativity.
Scientists at TU Wien and other institutions have developed a “quantum simulator” using ultracold atomic clouds to model quantum particles in curved spacetime, marking a major step toward reconciling quantum theory and the theory of relativity. The model system offers a tool to study gravitational lensing effects in a quantum field, which may lead to new insights in the elusive field of quantum gravity and other areas of physics.
The theory of relativity works well when you want to explain cosmic-scale phenomena — such as the gravitational waves.
