Spotting Quantum Black Holes in the Lab
Can we test speculations about how quantum physics affects black holes and the Big Bang?
Dark Matter Experiment Finds Unexplained Signal
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
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.
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
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.
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
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
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
Three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math.
