Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Volunteer astronomers sifting through infrared images from a retired NASA telescope have spotted a faint object racing through space at roughly 1 million miles per hour, fast enough to eventually ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

My travel schedule has become much busier recently, so I’ve been on a lot of flights. This inspired me to share what I think is a helpful metaphor. Please bear with me. In the late 1600s, Isaac Newton ...

The lasers alone would cost around one trillion dollars and the technology to create a nanocraft does not yet exist.

Astronomers tracing a string of strange radio bursts from the direction of the Milky Way’s center have zeroed in on GCRT J1745-3009, a rare and still poorly understood radio transient that flares ...

For decades, research universities have relied on federal funding, with no guarantee that it will last. Now their survival may depend on compliance with the government.
