APS Survey of 1,660 Finds Most Fundamental Physics Questions Lack Majority Support
3 articles · Updated · Gizmodo · May 13
APS said responses from about 1,660 participants showed broad disagreement across 10 major physics questions, with only one topic drawing a clear majority: 68% defined the Big Bang as a hot, dense state rather than an absolute beginning.
35.7% backed the Copenhagen interpretation of quantum mechanics, keeping it the top view but far from dominant; “no opinion” ranked among the top three answers for most questions, including quantum gravity at 28.7%.
50.8% said the early universe underwent cosmic inflation, but views split on what drives expansion now: time-varying dark energy edged constant-density dark energy by 1.9 percentage points.
Dark matter answers were even more fragmented, with axions at 17.4% beating once-favored WIMPs at 10%, while 20.6% chose a hybrid explanation and 15.1% had no opinion.
APS and the Perimeter Institute framed the weak consensus as evidence that frontier physics remains unsettled, with gaps in agreement pointing to where better data and theory are still needed.
If physicists can’t agree on the nature of reality, which long-standing cosmic puzzle will be solved first?
With experts divided on cosmology, what does this deep uncertainty reveal about the universe and our place in it?

"2026 APS Survey: 1,600 Physicists Disagree on Dark Matter, Quantum Gravity, and the Universe’s Biggest Questions"
Overview
The "Big Mysteries Survey," released by the American Physical Society’s Physics Magazine in May 2026, gathered responses from over 1,600 physicists and science enthusiasts to explore opinions on ten major questions in physics. The survey revealed a striking lack of consensus, showing deep divisions and significant fragmentation within the physics community. This challenges the idea that there are clear, majority-supported answers to the field’s biggest puzzles. The results, published in Physics Magazine and available online, highlight that many fundamental questions remain unsettled, with radically different ideas still being actively explored.
