For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural Revolution had stalled its development. Robert P Crease finds out more from ...

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 ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Samuel McKee does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very ...

Right now, molecules in the air are moving around you in chaotic and unpredictable ways. To make sense of such systems, ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

A recent interview with the well-known physicist Sean Carroll on “the physics of consciousness” gives us a great example of a reductive physicalist view of consciousness and the world around us. In it ...
