播音员：地球历史上发生过五次大规模物种灭绝事件，现在可能正在发生第六次。一些科学家认为我们正处于第六次大规模灭绝的边缘，另一些人则认为它已经开始。关于地球变化的原因，存在渐变论和灾变论两种观点。灾变论者认为地球变化发生迅速且剧烈，例如小行星撞击、大规模火山爆发、极移和巨大的太阳耀斑等。而渐变论者则认为地球变化缓慢且持续时间长。近年来，一些研究表明地球内核的减速或停止可能导致严重后果，甚至与地震有关。地震科学尚不完善，无法准确预测地震。但一些科学家通过观察潮汐力、地月引力以及动物行为等因素成功预测了几次地震。主流科学界对能够预测灾难的新理论持抵制态度。关于HAARP项目是否能够操纵天气和诱发地震存在争议。一些天文数字巧合可能暗示着某种重要的信息，例如与大规模灭绝事件周期性相符的26这个数字。关于太阳系中存在一个未被发现的大型天体（X行星或第九行星）的理论，以及它可能导致大规模物种灭绝的可能性。拉德克利夫波是一个巨大的星际结构，其周期性与大规模物种灭绝事件的周期性相符。主流科学界对挑战既有观念的新思想存在抵制，这与权力、金钱和名声有关。我们需要新的科学来理解地球变化的危险性，并给那些提出新思想的科学家一个机会。

The episode discusses the possibility of a sixth mass extinction, comparing it to historical mass extinctions and questioning whether there is anything we can do to prevent it.

Shownotes Transcript

Of all the species that have ever existed on Earth, 99% of them are gone. Most of those were wiped out during what are known as "Mass Extinction Events".

Since life emerged on our planet, there have been five mass extinctions. Sometimes these events last many years. But sometimes a mass extinction can happen very, very suddenly.

Some scientists think we're on the verge of a sixth mass extinction. Others think it's already begun.

But the question everybody asks is: "Is there anything we can do to stop it?"
