    在过去的9年里,科学家们一直对6500万年前恐龙灭绝的一个新观点争论不休,这个问题最终也许会得到解决。

    1980年,曾经有报道说,在一个6500万年前形成的沉积物薄层中,发现了稀有金属铱,它的含量异常丰富。一些人认为,这可能是由于一个巨大的小行星或彗星撞击地球的结果。这种撞击也许深入到了地壳内部,引起火山喷发,造成大火和潮汐大浪。许多尘埃进入了平流层中,结果造成在很长一段时间内阳光无法抵达地球表面。这也许是导致包括所有恐龙在内的许多地球生物灭绝的原因。

    毫无疑问,6500万年前地球上曾有过一次“大灭绝”,发生过一次“大劫难”。然而,并不是所有的科学家都认为这是由巨大撞击引起的。例如,1987年就有人指出,如果地球突然经历了一个火山爆发期,许多火山大致同时喷发,那么也能造成一个足以使生物大量灭绝的巨大灾难。

    因此,目前存在两种对立的理论,即“撞击说”和“火山说”。

    ​这不仅仅是一个学术问题,因为我们将来也许还会遇到这样或那样的大灾难(万一哪天某个星体要撞击地球,我们也许会知道如何来避免这种撞击)。我们需要尽可能多地了解这种事件所产生的影响,希望将来一旦面临这种事件,我们可以采取某种应急措施。
