Cooling metal bars to near absolute zero, suspending microscopic gold beads, or searching for signs that gravity might be ...

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

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 ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and out of superposition. A new line of work now argues that this picture is ...

It’s unclear whether science as a discipline—and scientists as people—will ever be able to answer some questions definitively ...

Super-intelligent, general-purpose humanoid robots are within our grasp, says the hype. Not so fast, says reality. Allow meus to explain.

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction.

A recent study proposes that the peculiar behavior of galaxies could be due to gravity functioning differently at vast cosmic scales, challenging the existence of dark matter.

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 ...
