A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

Sometimes the biggest puzzle in physics seems like the worst relationship in the universe. Quantum mechanics and general relativity are the two best theories in physics, but they have never been able ...

What exactly is … everything? What is space-time? At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

Falling into a black hole means facing extreme stretching, known as spaghettification, due to immense tidal forces. While ...

A team led by UNIGE has shown that the most mysterious component of our Universe follows the laws of classical physics, though some doubts still remain. Does dark matter obey the same physical laws as ...
