An evolution-inspired framework for how quantum fuzziness gives rise to our classical world shows that even imperfect observers can eventually agree on an objective reality ...

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

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 ...

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

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

The “Theory of Everything” is the dream of physics — one framework that connects gravity, quantum mechanics, space, time, and ...

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

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the supermassive black hole at the center of our galaxy. Sagittarius A* weighs ...

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 ...

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 ...
