According to a recent study conducted by a team of physicists at Stanford University, there is no logical explanation why airplanes are able to fly through the air. 'We understand the concepts of 'lift' and 'thrust,' but airplanes weigh like 800,000 pounds,' head researcher Gabe Koplowitz said. 'How does a huge metal tube just float up there in the sky without falling? And it's not even 'floating,' really, even though it looks like it is, because it's going 500 mph. Which means that when I'm sitting in an airplane, I'm actually going 500 mph, too. Me, Gabe Koplowitz. Jesus, how come we all don't vomit or have our hair blow back?' The study posited a number of potential theories to explain the phenomenon, including wind propulsion, suspension of gravity, and the possibility that clouds 'pull' the plane skyward. The Stanford team plans to devote the next two years to a new study on why telephones hear.
