The world, in perspective.

Data from the Large Hadron Collider has revealed evidence of a long-sought particle process that serves as a guide into the realm of the smallest scales ever probed

Scientists have created a miniature universe in the laboratory that could help answer one of the biggest mysteries in physics: What is time, and where does it come from? Using 24,000 ultracold atoms, a University of Birmingham researcher built an isolated quantum system that repeatedly expands and contracts, mimicking the Big Bang and a possible Big Crunch.

Physicists have discovered a strange new state of quantum matter in which ultracold atoms defy familiar organizational rules, forming a highly excited yet surprisingly orderly configuration called a "fractional Fermi sea." The discovery challenges established quantum theories and hints at exotic quasiparticles that scientists have dubbed potential "super-Fer
