    The airplanes can fly high up in the sky. Using the same phenomenon, I think the house can stand still in the air. If the pressure below the house is made large. Then, obviously enough upthrust would be generated to make a house stand still in the sky. What do you think? Is it possible?

    I'm not sure why you think that. airplanes cannot stand still in the air.

    If the pressure below the house is made large.
    A huge fan on the ground?

    If the air below the house is pressurized to a great enough level, you could just float the house on the now liquid atmosphere.

    Nature has been conducting experiments along this line for some time...



    On a more serious note, if the house is heavier than the air it displaces, gravity wins, does it not? As for getting the house to remain stationary, that will be problematical, in my opinion, for the air currents of the planet are almost always in motion and it would require some means to overcome these effects.

    My brother used to fly helicopters and 'hovering' is a more complicated maneuver than it appears. He took me for a flight on my birthday one time and we performed a 'toe-in' to a steep river bank, to simulate some of the tasks he used to perform during the caribou capture and monitoring work he did in conjunction with the Yukon wildlife services.

    I would not personally like my house to be in the air but that's likely just because I am accustomed to feeling the earth beneath my feet. I've been too long down from the trees, lol...

    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.
    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.”
