Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Researchers suggest that tiny wormholes could be punching microscopic holes through the fabric of space-time, Live Science reports, thereby driving the accelerating expansion of the universe. For ...

Gravitational lenses could allow us to find black hole binaries long before we're able to measure their gravitational waves. When you purchase through links on our site, we may earn an affiliate ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space ...

Did you hear the one about the star that died twice? In 2014, astronomers saw the explosion of the Refsdal supernova. Then, 360 days later, it went bang again. This bizarre sequence of events was down ...
