Physicists can’t agree on how the Universe works

A massive worldwide survey of physicists revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area of stronger agreement stood out: 68% said the Big Bang does not necessarily represent the beginning of time.

Researchers say the divisions show just how alive and unsettled the frontiers of physics remain. Physicists can’t agree on how the Universe works. Com The largest global survey of physicists ever conducted 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 ΛCDM (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.
