《孤筏重洋》是一部描述科学探险的纪实性作品。作者托尔·海尔达尔在太平洋中的波利尼西亚群岛上调查研究时,从那里的文物遗迹、民间传说以及太平洋上的风向潮流等方面发现了种种迹象,使他认为群岛上的第一批居民,是在公元5世纪从南美洲漂洋过海而来的。但是当时南美洲人的文化还处在石器时代,海上交通工具只有木筏,没有船。因此,许多科学家认为他的说法不对,最简单的原因是:人类不可能乘木筏横渡太平洋,安抵彼岸。 Raft Rays is a documentary work describing science expeditions. When the author, Tol Heldar, investigated the study in the Polynesian Pacific Ocean in the Pacific Ocean, there were signs of relics, folklore and trends in the Pacific Ocean that made him think the first inhabitants of the islands were In the 5th century ad from South America across the oceans. However, South American culture was still in the Stone Age, maritime transport only rafts, there is no boat. Therefore, many scientists think his argument is wrong. The simplest reason is that it is impossible for mankind to cross the Pacific with a raft to reach the other side.
