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

Notoriously ghostly particles called neutrinos may have revealed a crack in our understanding of all the particles and forces in the universe. The standard model of particle physics, which catalogues ...

Here’s what you’ll learn when you read this story: It used to be thought that bizarre interactions between subatomic particles known as neutrinos could be explained by another type of neutrino. The ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

DeepMind COO Lila Ibrahim discusses building powerful AI with care, ethics and a long-term focus on human impact.

The six-year Dark Energy Survey has released its full results, showing that two leading models of cosmology are equally valid ...

So, if you have learned nothing else from this story, please don’t underestimate the power of a strategically placed and ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a new paper suggests.

Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that two of its least understood components may be interacting, offering a rare window ...
