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

“Speed Of Sound” was a huge moment for Coldplay, as it kicked off the X&Y era and was the band’s first top-10 single in the US. Yet, the band has a contentious relationship with the song. Before ...

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 ...

NASA built an X-42A hydrogen-powered scramjet to reach speeds of Mach 9.6 for a brief moment in 2004. Therefore, this new ...

Queen’s performance at Live Aid 1985 was only 20 minutes, but it lived on forever. Propped up by an infectiously enthusiastic Freddie Mercury and Brian May’s screaming guitar, the performance has gone ...

Seven down. Three to go. Boom Supersonic—the developer of a 64-to-80-passenger commercial airliner that flies faster than the speed of sound—last week set speed and altitude records with its XB-1 test ...

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 ...

WHEN IT COMES to cosmic speed limits, light gets all the attention. Its velocity in a vacuum, a tad below 300m metres per second, is an absolute upper bound on how fast anything in the universe can ...

Humankind was once determined to break the sound barrier, as it was considered the ultimate achievement in speed. But our technology didn't stop there, as we've built experimental vehicles that can ...
