Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady ...

Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...

Cosmic strings are hypothesised one-dimensional topological defects formed during symmetry-breaking phase transitions in the early Universe. As these strings evolve, they intersect and form loops ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices. The research, published in Physical ...

We used three-dimensional imaging of ocean waves to capture freakish seas that produce a notorious phenomenon known as rogue waves. Our results are now published in Physical Review Letters*. Rogue ...
