We know that Einstein’s general relativity is, strictly speaking, wrong. That’s because it doesn’t account for quantum effects despite the fact that those e ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

Mind = blown.

For decades, black holes were thought to be invisible cosmic monsters that swallow everything, even light. But Stephen ...

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 ...

Nearly 40 years after Stephen Hawking's A Brief History of Time, Sarah Alam Malik's epic exploration of the cosmos reflects a ...

Published January 7 in the journal Nature, one paper tackled the age-old problem of nature’s construction with a bit of a twist: it suggests that living networks, like our brain, may use some of the ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...
