Researchers at UC-San Diego have engineered a negative-pressure gravity suit that could slow or even prevent the ravages of microgravity on astronauts' bodies suffered during extended spaceflight.

A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a kind of quantum instability that could trigger what's known as vacuum decay ...

A new theoretical study suggests that a strange flash of light appearing in empty space could reveal gaps in our current understanding of gravity and the nature of the Universe. The research, led by ...

Two physicists at the University of Sussex have made a startling discovery about black holes: they exert a pressure on their environment. Previously, black holes were believed to have a temperature ...

Negative pressure governs not only the Universe or the quantum vacuum. This phenomenon, although of a different nature, appears also in liquid crystals confined in nanopores. At the Institute of ...
