英译汉,解释下这个英语句子

这句话需要意译：他做出了足以震撼全人类的壮举,即完全改变了人们对宇宙的看法.
这句话包含双重否定,he didn't...和less...than...,字面意思就是：他没做不够震撼人类的事情.双重否定即肯定,即：他做了足够震撼人类的事情.
具体分析：he主语,didn't do谓语,anything less...宾语,其中less Earth-shattering than completely...修饰anything,作定语.
句子里包含less...than...搭配,意思是：不如...
比如：Her skirt is less colorful than mine.　她的裙子不如我的裙子色彩鲜艳.
