昆士兰大学领导的国际研究团队对2,884颗Ia型超新星进行了迄今最大规模分析1，该数据集整合了30年的历史观测资料1。这项研究发现暗能量可能随时间变化1，这一发现对现代宇宙学的基本假设提出了挑战。
研究团队将跨越三十年的天文观测数据重建为单一、一致的框架1。昆士兰大学教授Tamara Davis表示，"2024年DES超新星数据首次显示暗能量可能随时间变化，这项新编汇也显示与标准模型的偏离"1。这一发现得到了独立研究的佐证——DESI项目也发现了暗能量变化的证据1，两项完全独立的测量都提示暗能量具有时间依赖性1。研究团队的分析结果已在arXiv发布1，未来计划通过Dark Energy Bedrock All-Sky Supernova program (DEBASS)进一步扩展数据集1。
An international research team led by the University of Queensland has conducted the largest analysis of Type Ia supernovae to date, examining 2,884 stellar explosions and discovering evidence that dark energy may vary over time 1. This finding challenges a fundamental assumption of modern cosmology. The research consolidates 30 years of supernova observations alongside other cosmological measurements, providing fresh insights into how the universe's expansion has evolved 1.
According to PhD candidate Ryan Camilleri, the team has successfully "reconstructed three decades of astronomical observations into a single, unified framework" 1. Professor Tamara Davis noted that 2024 data from the Dark Energy Survey initially suggested temporal variation in dark energy, and the new comprehensive compilation similarly reveals deviations from the standard cosmological model 1. Independently, the DESI project has also detected evidence of dark energy variation, with both completely separate measurements pointing toward the possibility that dark energy changes with time 1. The findings have been published on arXiv 1, and the research team plans to expand the dataset through the Dark Energy Bedrock All-Sky Supernova program (DEBASS) 1.
