Quantum particles act as if they instantly 'agree' at any distance. Three physicists propose solutions: abandoning reality, the limitations of observers, or extra dimensions. This changes the very foundation of how we understand the world.
🎯 The strength of quantum connections in our three-dimensional space is limited (Tsirelson's bound). In worlds with a different number of dimensions, correlations could be much stronger.
🎬 Instantaneous particle connection is the physical analogue of the ansible from science fiction, a device for communication at any distance, described in Ursula Le Guin's novels.
