Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Disclaimer: I am very much a physics noob. This might be a nonsensical question. That spacetime can be curved or warped is something I can grasp, but I keep getting stuck on one specific aspect of how ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

Einstein's general theory of relativity, published in 1915, relates spacetime curvature to matter distribution, leading to the Schwarzschild solution describing a black hole. The Schwarzschild ...

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 ...
