Getting the most out of cosmic maps
Los Angeles CA (SPX) Jan 22, 2025 A University of Michigan-led research initiative is paving the way for cosmology to fully utilize the capabilities of telescopes and instruments tackling the universe's biggest questions. The project highlights a novel computational method that extracts significantly more information from cosmic maps depicting the clustering and distribution of galaxies across the universe. Such maps are critical tools for exploring dark energy, dark matter, and other enigmatic cosmic phenomena. h3>The dark ... read more |

Building safer and more accessible nuclear clocks
Los Angeles CA (SPX) Dec 26, 2024 Scientists are making significant strides in creating nuclear clocks, a new frontier in ultra-precise timekeeping. Unlike optical atomic clocks that depend on electronic transitions, nuclear clocks harness the energy transitions within atomic nuclei. These transitions are less influenced by external forces, offering potentially unparalleled timekeeping accuracy. Despite their promise, nuclear clocks face steep challenges. The isotope thorium-229, essential for these clocks, is rare, radioactive, a ... read more 
Dark energy theory challenged by evidence of a 'lumpy' UniverseLondon, UK (SPX) Dec 23, 2024 A groundbreaking study from researchers at the University of Canterbury in New Zealand proposes that dark energy, a long-debated concept in cosmology, may not exist. Using improved supernovae light ... more |
