Physicists Divided on What Quantum Mechanics Says about Reality

A century after quantum mechanics' inception, physicists remain divided on its interpretation of reality, as shown by Nature's survey of 1,100 researchers. The Copenhagen interpretation is favored by 36%, with alternatives like Many-Worlds (15%) and Bohmian mechanics (7%) also supported. Disagreements persist on whether the wavefunction is real (36%) or just mathematical (47%), and if a quantum-classical boundary exists. Despite these philosophical differences, 86% of respondents value attempts to interpret quantum mechanics physically, while the theory continues to succeed in practical applications.
