Big Mysteries Survey: Physicists' Views on Cosmology, Black Holes, Quantum Mechanics, and Quantum Gravity

We present results from the Big Mysteries Survey, a large-scale survey conducted through the American Physical Society’s Physics Magazine on foundational and controversial topics in contemporary physics. The survey provides a snapshot of physicists’ views on issues in cosmology, black-hole physics, quantum mechanics, quantum gravity, and anthropic coincidences. A central finding is that several positions often described publicly as field-wide ``consensus’’ views are, in practice, supported by much narrower majorities or by pluralities rather than majorities.
