研究人员声称超新星可能因危害地球臭氧层而引发了两次重大大规模灭绝。 Researchers claim supernovas may have triggered two major mass extinctions by harming Earth's ozone layer.

研究者认为超新星可能已经造成地球最大的两次大规模灭绝 通过剥除地球的臭氧层 使生命暴露在破坏性辐射之下 Researchers suggest supernovas may have caused two of Earth's largest mass extinctions by stripping the planet's ozone layer, exposing life to damaging radiation. 该研究计算出,大约2.5个超新星每10亿年可能撞击地球,可能与3.72亿和4.45亿年前的灭绝事件相关联。 The study calculates that about 2.5 supernovas could impact Earth every billion years, potentially linking to extinction events 372 million and 445 million years ago. 然而,这一假设缺乏直接证据,突出表明需要进一步调查以证实其联系。 However, the hypothesis lacks direct evidence, highlighting the need for further investigation to confirm the connection.
