国际天体物理学家团队发表新研究，驳斥去年南韩团队提出的宇宙膨胀减速假说，重新确认宇宙正在加速膨胀1。研究团队指出，南韩研究存在关键分析缺陷，包括将星系年龄错误地等同于超新星年龄，以及未能正确考虑星系质量因素1。这项研究由Southampton大学Phil Wiseman博士领导，包括2011年诺贝尔物理学奖得主Adam Riess和Brian Schmidt等研究员1。
Wiseman博士表示："我们的当前理解宇宙命运仍然稳健"1。研究确认了长期以来的标准宇宙学解释——推动宇宙加速膨胀的暗能量理论依然成立1。该论文已发表在《Monthly Notices of the Royal Astronomical Society》期刊上1。
An international team of astrophysicists has published new research refuting claims made by a South Korean team last year that the universe's expansion was slowing down, reaffirming instead that cosmic expansion continues to accelerate.1 The study, led by Dr. Phil Wiseman of the University of Southampton and including 2011 Nobel Prize in Physics laureates Adam Riess and Brian Schmidt, identified critical flaws in the previous analysis, including incorrect estimations of supernova ages and a failure to properly account for galaxy mass.1 "Our current understanding of the universe's fate remains robust," Wiseman stated.1
The South Korean team had published their findings in November, proposing that the universe might be entering a phase of decelerated expansion.1 However, the new research demonstrates that these conclusions were based on methodological errors, particularly the conflation of galaxy age with supernova age.1 The findings support the standard cosmological explanation for cosmic acceleration: dark energy.1 The research has been published in the Monthly Notices of the Royal Astronomical Society.1
