444. 宇宙膨胀可能减速的研究

from 知为谁 · host 知为谁

这两份资料均讨论了一项重要的宇宙学研究，该研究对宇宙加速膨胀的现有理论提出了质疑。具体来说，研究人员通过修正Ia型超新星观测中的恒星年龄偏差，发现遥远超新星的亮度变化更多地是由于其宿主星系的恒星特性，而非仅仅是宇宙的膨胀效应。经过这种校正，数据显示宇宙的膨胀可能正在减速而非加速，这表明暗能量可能随时间推移而减弱。这一发现挑战了曾获诺贝尔奖的理论，并暗示宇宙的最终命运可能是“大挤压”，标志着宇宙学的一个重大范式转变。内容来源：https://www.theguardian.com/science/2025/nov/06/universe-expansion-slowing-not-accelerating-nobel-prizehttps://phys.org/news/2025-11-universe-expansion-evidence-mounts-dark.html
