We thought you could not exceed the speed of sound too. As speed increased, so did drag, a

nd at the speed of sound, you would have infinite drag. At the speed of light, in theory, you should have infinite mass. As you approached the sound barrier, drag did go up exponentially, to a point, and then dropped down. It peaks again at Mach 2. So perhaps mass does the same @ speed of light?
