The Core Movie Review Message Board and Comments

The ridiculous feats of engineering purposing that a possible machine could drill through the Earth removing all solid state from its path using sonic lasers, that at once an object passes through the air it creates a series of pressure waves, these waves travelling at the speed of sound amazing ’move the object’ The so insane theory of such technology is ‘quite funny’ yet the bad physics provides a ‘non-stop’ surprise. One of my personal favourite bad science points of this movie would have to be their suits of which can outstand not only the intense heat of below the Earths surface but also the pressure of all mass above them (they say in the movie it’s about 800,000 p ounds per square inch.) but not can they take that kind of pressure, but is actually able to resist it enough to move. When a crack in the top of the geode lets in magma, which falls on the commanders head, which burns through his suit and kills him. He falls backward and sinks into the pool of magma. (not lava which was said in the film) Objects sink in liquid if they are denser than that liquid. A human is roughly as dense as water, but liquid rock is far denser than water. So in reality the Commander would float in the pool of liquid rock, and not sink,saying this the commander would momentarily be crushed like a tin can! under such high pressures. It's a great film for science lessons as it teaches alot of points of the Earth's make up (planet peach!)and is good for students finding incorrect science. I found it a fairly useful resource and I know my students enjoyed it.
