Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...

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 ...

On Mars, the speed of sound depends on its pitch. All sound travels slower through Mars’ air compared with Earth’s. But the higher-pitched clacks of a laser zapping rocks travels slightly faster in ...
