Einstein’s big shift: He replaced Newton’s pull with curved spacetime, showing gravity as geometry rather than a force. Time isn’t universal: Special and general relativity reveal that motion and ...

Instead of tackling black holes head-on, researchers translated Hawking radiation into the language of particle physics using ...

For decades, we thought the biggest black holes were born from the most massive stars, but a groundbreaking study published in May 2026 flips that script. Scientists analyzing the latest gravitational ...

A link between particle physics and gravity equations, called the double copy, applies to Hawking radiation, creating a new ...

Among them is the Season 5 finale of Quantum Leap, an NBC sci-fi show that first aired in 1989 and followed a physicist ...

A 10-year effort to measure gravity, a fundamental force in the universe, has failed to come up with a conclusive answer.

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

Scientists determined that if those theories are true, there must be a limit to how accurately time can be measured. This ...

One of the best-performing models in cosmology is also one with the least physical rationale behind it. Columnist Leah Crane ...

We all have this image in our mind of what rich people spend their money on. But as it turns out, they also spend their ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...
