Pero no quedamos en que eso no lo sabia ni la avatarpedia? Y que si flotaban por la influencia gravitatoria del planeta vecino era absurdo que el agua cayera normalmente, pero en cambio si levitaba porque tenia un huevo de mineral dentro era raro que los humanos estuvieran tan centrados en un arbol poblado por navis que no debe tener ni la mitad de mineral debajo, dado que no flota.
Es loque pasa cuando dejo de escribir, friki-posts, que no se actualizan las fuentes.
Va, venga.
The Floating Hallelujah Mountains
The topic of how an entire mountain range can bob over the landscape like corks is never explicitly addressed in the film, yet the explanation is woven throughout the story. It all has to do with superconductors. When superconductors are in the presence of a magnetic field, they can float. "Avatar's" alien world of Pandora, it turns out, is simply a massive superconductor. At the very beginning of the story, we are told that humans have come to Pandora to mine unobtanium.
Unobtanium is the ultimate superconductor. (The very name, "unobtanium," is a nod to sci-fi afficionados, who coined the word to describe a material with mythical properties.) In Cameron's world, unobtanium can conduct electricity without resistance at room temperature; the best current superconductors work only when the temperature is below minus 200 degrees F. The discovery of unobtanium, which exists only on Pandora, revolutionized technology on Earth, the story goes, and the future human economy is dependent upon it.
On Pandora, however, entire mountains loaded with unobtanium float in the world's massive magnetic field. In a glimpse of how thoroughly Cameron has thought through the science behind his creation, he and his team have written a 380 page "Pandorapedia" that explains (among other things) the tectonics behind how such mountains could form.
Natural Phenomena Inspire Cameron's Visions
In effect, they crumble upward. This happens because Pandora is not a planet but a moon of a gas giant the size of Saturn – the fictional planet Polyphemus. Moons of gas giants are constantly tugged and deformed by the stresses of gravity. One of Jupiter's moons, Io, is pulled so violently by the gravitational forces of both Jupiter and Jupiter's other large moons, that it has ground tides – the ground literally rises and falls like a sea tide on Earth.
On a second moon of Jupiter, Europa, these tidal forces have heated the interior of the moon to the point that part of its crust has melted, creating a sea of liquid water beneath a surface of ice, scientists say. On Cameron's Pandora, those tidal stresses have fractured the landscape, and, in the case of the Hallelujah Mountains, sent it up into the sky. A companion book to the movie explains the larger process: "This … energy drives continental drift at a much faster rate than on Earth, causing tectonic plates to fracture more extensively because of the increased stress."
Cameron's fascination with the deep sea has already led to one of the most successful films of all time: "Titanic." It appears to have shaped "Avatar," too. The oceans' depths have a curious answer to sunlight, which has never been seen there. It's called bioluminescence – organisms' ability to create their own light. Fireflies are perhaps the most obvious example, but the bioluminescent fish of the deep sea tell a different story – that nature, when deprived of light, sometimes creates its own.
On Pandora, where the nights can be many Earth days long, Cameron has suggested that an entire bioluminescent ecosystem could emerge. This is where Cameron's decision to make Pandora a moon – and not a planet – comes in. Moons, including Earth's, are typically "locked" to their planets, with one side eternally facing the planet and one side eternally facing out into space. What this means is that one day on a moon equals the time it takes to orbit its parent planet – a long time.
To watch the phases of our Moon is actually to watch the lunar day in real time. A full moon is midday for the side of the Moon facing the Earth. A new moon is midnight for the side of the Moon facing the Earth. In other words, a lunar day takes more than 27 Earth days. And that means a very long night.

La idea original de la película se llama Project 880. Como suele pasar, se cortan muchas cosas interesantes, virus, suicidios de avatares, sangre...
Se explica que los humanos intentan explotar las montañas de mineral pero las pérdidas de vidas, el transporte y uso del material y varias causas más lo hacen inviable
En la idea original el mineral estaba principalmente en las montañas, pero se trasladó la acción(y el mineral) al árbol madre.
"In
Avatar the humans attack Hometree because they're just sick of waiting to get at the unobtainium. Moving unobtanium to Hometree makes much of
Avatar's storytelling more streamlined, but it also makes the flying mountains nothing but a novelty and creates a weird lack of urgency in the humans' mission. "
