纪录片《恐龙灭绝真相》 第20期 争论不休

This is still one and the same impact, we have the Chicxulub impact here,

这还是一次碰撞，假设这里就是希克苏鲁伯大碰撞，

very quick sedimentation¹ by Tsunami² waves, and at the very end we get the Iridium from the Chicxulub impact

海啸带来的物质迅速沉淀，最后是希克苏鲁伯大碰撞带来的铱元素，

so the dinosaurs³ got extinct right here,

所以恐龙就是在这里灭绝了，

as a consequence of the Chicxulub impact and not by a second impact on some unknown place in the world.

原因就是希克苏鲁伯大碰撞，而并非世界上某个未知地点的第二次碰撞。

Jan Smit and Gerta Keller had fought each other to deadlock⁴.

Jan Smit和Gerta Keller的观点针锋相对。

Smit still represents the view of the great majority of scientists in this field

but there is now some support for Gerta Keller's position.

但是现在已有一些人转而支持Gerta Keller。

Neither side is about to back down.

双方都不愿意放弃自己的论点。

We looked at all evidence and I refute everything.

我们研究了所有证据并一一驳倒。

There's not a single argument which holds ground.

这不仅仅是一次为自己验明正身的辩论。

He built his career on this impact Tsunami hypothesis

他在碰撞海啸假设的基础上建立起了自己的事业，

and right now he's feeling this hypothesis crumble⁵ in front of his eyes.

而现在他正看着这种假设在自己面前坍塌。

But while two groups of scientists were obsessed⁶ with the debate about which was the guilty impact,

another thought the whole thing was completely beside the point.

另一批却站出来指出整个事情完全脱离了主题。
