Spotting Quantum Black Holes in the Lab

July 15, 2020

Can we test speculations about how quantum physics affects black holes and the Big Bang?

Dark Matter Experiment Finds Unexplained Signal

June 17, 2020

Researchers say there are three possible explanations for the anomalous data. One is mundane. Two would revolutionize physics.

Growing Anomalies at the Large Hadron Collider Raise Hopes

May 26, 2020

Collider physicists report that several measurements of particles called B mesons deviate from predictions. Alone, each oddity looks like a fluke, but their collective drift is more suggestive.

What Goes On in a Proton? Quark Math Still Conflicts With Experiments.

May 6, 2020

Two ways of approximating the ultra-complicated math that governs quark particles have recently come into conflict, leaving physicists unsure what their decades-old theory predicts.

Neutrino Asymmetry Passes Critical Threshold

April 15, 2020

The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing.

Why Do Matter Particles Come in Threes? A Physics Titan Weighs In.

March 30, 2020

Three progressively heavier copies of each type of matter particle exist, and no one knows why. A new paper by Steven Weinberg takes a stab at explaining the pattern.

Axions Would Solve Another Major Problem in Physics

March 17, 2020

In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty.

Top Dark Matter Candidate Loses Ground to Tiniest Competitor

November 27, 2019

Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.

Neutrinos Lead to Unexpected Discovery in Basic Math

November 13, 2019

Three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math.
