John O'Mara: 世界末日的感觉取决于世界末日的定义(地球毁灭还是所有生物灭绝),以及末日发生的具体方式。大型天体撞击地球会导致大量尘埃进入大气层,阻挡阳光,从而破坏食物链,最终导致地球上大部分生命灭绝,这可能是恐龙灭绝的原因。超新星爆发会释放出巨大的能量,破坏地球大气层,影响植物和动物的生存。太阳最终会耗尽燃料,膨胀到足以吞噬地球。尽管这将在50亿年后发生,但这是必然会发生的事件。了解宇宙的科学知识能帮助我们减少对世界末日的恐惧,因为我们可以找到应对方法,并且这些事件发生的概率极低,时间尺度以亿年计。 Sarah Stewart-Taylor: 全球变暖会导致一系列缓慢的变化,例如洪水、人口迁移、粮食短缺等,这些变化会逐渐影响人们的生活。即使在遥远的未来,太阳吞噬地球时,人类的基本需求(爱、食物、住所)仍然存在。思考世界末日可以激励人们采取行动应对全球变暖等问题;从宇宙循环的角度来看,我们并不会真正消失,而是会转化为其他的存在形式。 M.T. Anderson: 地球的终结将在极其遥远的未来发生,那时人类可能已经进化或迁移到其他星球,地球的毁灭对他们来说可能就像祖先房屋的倒塌一样微不足道。

Shownotes Transcript

This episode looks at a big question, a really big question. It's about the end of the world and what it might feel like. Parents: this episode is about asteroids and supernovas; some kids may find this episode a bit scary, or may have never considered those possibilities before, so you may want to listen first on your own.
