Galaxy clusters are the most massive objects in the universe held together by gravity, containing up to several thousand ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

There, over six years, neutrinos from two separate particle beams were studied by MicroBooNE, a state-of-the-art detector ...

Singing sand dunes create a deep booming sound during avalanches due to synchronized sand grain vibrations under hot, dry ...

The idea that we might be living in a simulated reality has worried us for centuries. Now physicists have found some ...

The X‑arithmetic technique offers a powerful new way to map the physics of other galactic structures across the universe and ...

In the end, the Universe becomes a place where gravity and quantum physics slowly turn all mass into faint streams of particles.

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to ...

From a particle smasher encircling the moon to an “impossible” laser, five scientists reveal the experiments they would run ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...
