"But most of the time, the movie neglected to put it in," he says. Kakalios noticed a few sonic booms in the recent blockbuster Superman Returns. It travels at the speed of sound to your ear, which detects it as a loud noise called a sonic boom (see diagram, p. ff you were to spot Superman dashing by, just wait The shock wave would follow. The pressure waves pile up in front of him, forming a high-energy shock wave. These parting air molecules create pressure waves, which are sound waves, around the object But when Superman flies faster than the speed of sound, the air molecules can't move out of his way fast enough. And when you finally do hear him, what a racket you would hear! Why? When any object flies through air, it pushes air molecules aside.

If Superman were in such a hurry, you'd see him zip past you before you would hear him fly by. If Superman flies at the speed of sound through 20C (68F) air, he would be moving at a rate of 342 meters (1,122 feet) per second. And how fast those waves travel is partly determined by what medium the waves are moving through-gases, liquids, or solids-and the medium's temperature.
Most bullets move faster than the speed of sounds, says Kakalios. Kakalios believes that Krypton's gravity must be a whopping 15 times stronger than Earth's.īesides making impossibly large leaps, Superman can also move faster than a speeding bullet. So when he pushes off Earth's surface, his Krypton-adapted muscles send him sky high. his body is adapted for his home planet of Krypton. Similarly, Superman can skip over buildings on Earth because. If you were to jump on the moon using the same amount of force that you would on Earth, you would leap six times higher than at home. There, the force of gravity is six times weaker than that on Earth. If you want to leap like a superhero, Kakalios suggests a visit to Earth's moon. So you can only jump a short distance before gravity tugs you back down to the ground. But the human body can exert a limited amount of force. The greater the force of your push, the larger the net upward force and the higher you'll jump. When you jump, you use your body to push against the ground. To lift off Earth's surface, you need to exert a force that is strong enough to offset the downward pull of gravity. This attracting force tugs at you, keeping you close to the ground. Why can't humans jump like Superman? "Your body is adapted to deal with Earth's gravity," says Kakalios. "Personally, I'm lucky to leap over a trash can," says Kakalios. Said that he could hurdle a 20-story building. When Superman first appeared in comic books in 1938, it was
Read on as he explains what makes Superman so awesome. Kakalios is so mesmerized by physics-defying superpowers that he wrote a book called The Physics of Superheroes. "None of this is possible for humans," Kakalios says. Superman can leap tall buildings, fly, and see through objects. What makes the superhero so captivating? "He is exempt from the laws of nature," says James Kakalios, a fan and a the University of Minnesota.
