In a study, published in the journal Science Advances, the physicists said to calculate for the threshold of the speed of sound, they factored in the two dimensionless fundamental constants.

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 ...

The upper limit on the speed of sound in solids and liquids depends on just two dimensionless quantities – the fine structure constant and the proton-to-electron mass ratio. That is the surprising ...

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 ...

An MIT engineer has a radical idea for determining just how strong a hurricane is: Analyze the sound of its roar, recorded by hydrophones 800 meters under the surface, to calculate the speed of ...
