Are the Hometrees in James Cameron’s Avatar Structurally Possible?

Rowan Reynolds, Chris Ringrose, Robbie Roe


In James Cameron’s Avatar, the Hometree is a sacred home for the Na’vi clans. These “trees” are said to be made of several thinner trees which have grown together to form a larger structure, suitable for its inhabitants. On Earth, the largest trees are significantly smaller (by almost a third). This paper concludes that factors such as reduced gravity result in only 22,100 N m-2­ of compression, low enough to allow the tree to stand.
