[ad_1] For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity, as allowed by the laws of quantum mechanics, an ascending glissando of the frequencies at which the fluid resonates. This research can help us understand some of the most extreme …

[ad_1] Just over five years ago, humanity still had to detect gravitational waves. Now, the observations are pouring in at amazing speed. Over a span of six months last year, the LIGO-Virgo collaboration detected, on average, 1.5 gravitational wave events per week. From April 1 to October 1, 2019, the …
