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

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...

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 ...

The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a ...

In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very ...

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 ...

Recent theoretical advances have underscored the significance of momentum space geometry in the realm of relativistic physics. Traditional notions of flat momentum space are being re-evaluated in ...

The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide. Quantum theory works well when describing ...
