Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers at the Max Planck Institute for the Science of Light (MPL) ...

A new study suggests that people are more likely to consciously notice neutral spoken words than negative ones when ...

Researchers claim sound waves do carry mass – gravitational mass. This implies that a sound wave not only is affected by gravity but also generates a tiny gravitational field. Our findings are valid ...

Heavy metal music isn’t heavy after all – it is actually the opposite. Sound waves have mass and can interact via gravity, but that mass is negative. In other words, sound floats upwards. Angelo ...
