According to our best understanding, the universe is expanding – and is doing so at an accelerating rate. This is believed to ...

Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational ...

A newly merged black hole does not become quiet at once. It vibrates, sheds energy through gravitational waves and produces a ...

When it comes to losing weight, it turns out the simple math of counting calories doesn’t always add up. Fad diets come and ...

The nature of light and photons reveals deep insights into spacetime, showing how they traverse without time, reshaping our ...

When it comes to losing weight, it turns out the simple math of counting calories doesn’t always add up. Fad diets come and go, but the underlying message almost always follows a simple equation: If ...

Albert Einstein’s general theory of relativity predicts that a rotating mass like the Earth pulls the fabric of space and ...

When it comes to losing weight, it turns out the simple math of counting calories doesn’t always add up. Fad diets come and ...

The laws of physics that concern heat and work could gain a firmer mathematical footing thanks to “gauge theory”, which ...

Scientists from Brazil are challenging the traditional view of universal constants, proposing that only one constant—time itself—is needed to measure relativistic spacetime. The research team argued ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics apply ...
