韩国的一项研究对加速宇宙扩张的想法提出了挑战,表明暗能量正在减弱,根据重新分析的超新星数据,宇宙可能会减速。 A South Korean study challenges the idea of accelerating cosmic expansion, suggesting dark energy is weakening and the universe may slow down, based on reanalyzed supernova data.

南韩研究于2025年11月6日发表, 质疑长久以来认为宇宙扩张正在加速的信念, A South Korean study published November 6, 2025, challenges the long-held belief that the universe’s expansion is accelerating, suggesting instead it may be slowing due to weakening dark energy. 研究人员对Ia型超新星数据进行了再分析,发现其亮度随宿主星系的年代而不同,引入了先前被忽视的偏差。 Researchers reanalyzed Type Ia supernovae data, finding that their brightness varies with the age of host galaxies, introducing a previously overlooked bias. 在纠正了这一点后,加速扩张的证据消失殆尽,与显示减速和潜在未来“大紧缩”的模型更加一致。 After correcting for this, the evidence for accelerating expansion disappears, aligning better with models showing deceleration and a potential future "big crunch." 这些调查结果得到DESI调查数据的支持,可以解决哈勃的紧张局势,促使宇宙学发生重大转变,尽管专家仍然谨慎,等待即将到来的观察结果确认。 The findings, supported by DESI survey data, could resolve the Hubble tension and prompt a major shift in cosmology, though experts remain cautious, awaiting confirmation from upcoming observations.
