Physicists can’t agree on how the Universe works
A global survey of physicists reveals a lack of consensus on fundamental questions, including the nature of dark energy and the reconciliation of gravity with quantum mechanics. Only two topics, the Big Bang and cosmic inflation, received majority agreement among respondents.
Why it matters
The lack of consensus highlights that modern physics is at a critical juncture, with standard models being challenged by new observational data.
The largest global survey of physicists ever conducted has revealed just how unsettled some of the biggest questions in modern physics remain. Researchers found surprisingly little agreement on topics ranging from black holes and dark matter to the long-running effort to reconcile Einstein's theory of gravity with quantum mechanics.
Even the standard model of cosmology, known as CDM (Lambda Cold Dark Matter), failed to win support from a majority of respondents. That result may reflect recent findings from the Dark Energy Spectroscopic Instrument (DESI), which suggested that dark energy could change over time. Such a possibility would conflict with the standard model, which assumes that dark energy remains constant.
And cosmology was far from the only area where physicists disagreed.
Standard Answers Fail To Win Broad Support
