Next stop: Easter Island

Alright, this one contains a few reading prompts (or reasons to comment if you don’t have the time to look it up):

Living in Norway, one cannot but think of Thor Heyerdal whenever Easter Island comes up in discussion (as it is wont to do, you know). The man had an idea: Humans colonised polynesia from South America, and he set out to prove it by using a raft to travel from South America to Polynesia.

It strikes me that this is how the story of another Norwegian celebrity is always told: Kristian Birkeland had an idea about how aurorae worked and reproduced the lights in his lab. Case closed. Right?

No.

Where Birkeland’s experiment fit with the rest of the available science, Heyerdahl’s went against the rest of the available evidence.

One of them turned out to be wrong.
One of them turned out to be right.
None of them proved anything by themselves. 😉
