Waterworld movie avatar
Even withoutbrain-computer interfaces, telepresence units are now allowing surgeons toperform life-saving operations from afar. Still, scientists in reallife are making advance after advance when it comes to brain-computer interfacesto control robot arms and type and speak through machines. Even ifaliens have DNA, humans would probably have more in common with corn oranything else on Earth than with life on Pandora. The bodies in question resemblethe native blue-skinned humanoid race, the Na'vi, although they are hybridsthat incorporate the DNA of their operators.īuildinga body that weaves together human and alien DNA might be far-fetched. Thedevices that give the film its name are avatars ? artificial bodies the maincharacters operate wirelessly by thought alone. The filmsshow these magnetic fields can interfere with technology, just as they would inreal life ? although, apparently, not whatever wireless links which allow themain characters to link with their "avatars."
Just as real-world superconductors can float in the presence of amagnetic field, mountains on Pandora apparently loaded with unobtanium canfloat in the powerful magnetic pockets that dot the moon's surface. (Technically, since it's a mineral, it mightbetter be called "unobtainite," but that's a pretty nerdy quibble.)Unobtanium is the best superconductor known, and apparently works at roomtemperature. Thedraw that Pandora has for humans is a naturally occurring ore dubbed"unobtanium," an old in-joke in science fiction for materials withphysically impossible qualities. Jupiter's moonsexist within an intense radiation belt of electrons and ions trapped in theplanet's magnetic field, and Saturn's gravitational pull leads to extraordinarytidal effects that may have once ripped apart nascent moons to produce itsrings, and today can drive winds and volcanic eruptions on its moon Titan. However,life on a gas giant's moon might present a host of challenges. A fewyears ago, this might have seemed implausible, but most of the alienplanets scientists have discovered so far are in fact gas giants that areexceedingly close to their stars. Tropicalrainforests cover most of Pandora's continents, which suggests its motherplanet must be fairly close to its sun to take advantage of its light. In reality, scientists might soon be able to detect habitable moons withthe James Webb Space Telescope and also study their atmospheres for keylife-related gases such as oxygen, and water vapor. The larger of the two real, sunlikestars that make up this alien system, Alpha Centauri A, is the fictional Pandora'ssun. And the AlphaCentauri system could be a place worth looking. Whileastronomers have yet to discover moons beyond our solar system, they expectto.
