The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 ...

Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. This exercise was largely theoretical: The researchers found that the answer, which is ...
