No plant type life forms to maintain atmosphere on that volcanic Hades.<br /><br />Also, the radiant heat from all the lava should have incenerated the characters. It was evident to me that no one involved in storyboarding that scene has never been near a burning building.<br /><br />Still I liked the movie, and I'm sure various technical specifics bothered other viewers too. Just thought that one detail pushed too far.<br /><br />Fumes from all the lava should have been unsurvivable, too. Maintaining mountains on such an intensely volcanic world should be quie difficult, too.<br /><br />In an establishing shot at the beginning of the sequence, they showed a nearby, much larger planet. I think the implication exists in the movie that the volcanic activity was caused by tidal effects.<br /><br />I don't see a volcanic aerosol cooling effect being operative on such a world, the percentage of heating of the planets surface provided by sunlight compared to the volcanic heating would be miniscule, increasing the albedo of such a world won't cool it.<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>
