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

Physicists tested sound as it travels through different materials Sound can almost reach its upper limit when traveling in solid atomic hydrogen The finding is vital in different fields of studies ...

The fastest possible speed of sound — 22.4 miles per second, nearly twice its speed in air at the Earth's surface — has been calculated for the first time. British researchers found that such speeds ...

Upper limit: a US Navy F/A-18 travelling near the speed of sound in air. The white halo comprises water droplets that have condensed from the air because of the sudden drop in pressure behind the ...

When we talk about the speed of sound, we usually mean how fast it moves through air. But it can travel much faster through other media, and now scientists at the University of Cambridge and Queen ...
