- LIGO's gravitational wave detectors measure changes less than the width of a proton.
- LIGO detected its first gravitational wave in 2015 from colliding black holes.
- Rana Adhikari and team used AI to improve LIGO's design for broader frequency detection.
- AI-designed interferometer included a counterintuitive 3km ring to reduce quantum noise.
- AI's design could have improved LIGO's sensitivity by 10-15% if implemented earlier.
- Entanglement swapping allows previously non-interacting particles to become entangled.
- Krenn's team used PyTheus software to design quantum experiments via graph optimization.
- AI discovered simpler configurations for entanglement swapping than human designs.
- AI has been used to find patterns in dark matter and symmetries in particle physics data.
- Large language models may soon help automate hypothesis construction in physics.
