Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.
Three physicists have proposed a new solution to one of the deepest mysteries in particle physics: why the Higgs boson has such a tiny mass.
A statistical anomaly in the signal from rare particle decays at the Large Hadron Collider offers hope that new discoveries might be around the corner.
In his latest book, the Nobel Prize winner Steven Weinberg explores how science made the modern world, and where it might take us from here.
The Relativistic Heavy Ion Collider fired up for its 15th run to take a deeper look at the building blocks of atoms.
Early in cosmic history, our universe may have bumped into another — a primordial clash that could have left traces in the Big Bang’s afterglow.
Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics.
For five years physicists have been tantalized by possible evidence of dark matter in the Milky Way’s center. But new results from small satellite galaxies have complicated the story.
Newly discovered particles are forcing physicists to extend their simple picture of subatomic interactions or replace it with a more nuanced understanding.
