Fundamental constants place a new speed limit on sound – Finance Brokerage

Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances.
Sound zips along at different rates in different materials moving faster in water than in air for example. But under conditions found naturally on Earth, no material can host sound waves that outpace this ultimate limit, which is about 100 times the typical speed of sound traveling in air.
The teams reasoning rests on well-kn…
