Experimentally verified thermodynamic model reduces relative uncertainty of previous model by over one order of magnitude.

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 ...

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make ...

The universal speed limit of any kind of wave – be it electromagnetic or gravitational – travelling through a vacuum has been known since Albert Einstein developed his theory of special relativity in ...
