Dark Matter Elusive: Physicists Rethink Cosmic Mysteries
Summary
Physicists confront cosmic puzzles as dark matter experiments yield no particles, prompting theories like 'fuzzy dark matter' waves affecting galaxies or entropy-based gravity models that negate the need for dark matter, reshaping our understanding of the universe.
Key Points
- Dark matter experiments fail to detect particles, sending physicists scrambling for new explanations
- Some propose 'fuzzy dark matter' that behaves like waves, leaving observable effects on galaxies
- Others challenge gravity itself, suggesting the laws of entropy can account for cosmic motions without dark matter
