Discoveries Fuel Fight Over Universe’s First Light
Researchers have looked further into the early universe than ever before. The new discoveries should make clear just how much black holes contributed to the reionization of the universe, even as they’ve opened up questions as to how such supermassive black holes were able to form so early in the universe’s history.
A Defense of the Reality of Time
Time isn’t just another dimension, argues Tim Maudlin. To make his case, he’s had to reinvent geometry.
Swirling Bacteria Linked to the Physics of Phase Transitions
The new experiments suggest that simple models can explain the behavior of thousands of interacting organisms.
The Quantum Thermodynamics Revolution
As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information.
The Secret Power of the Cell’s Waste Bin
Trash collectors in the cell moonlight at the controls of the genetic machinery.
A Long-Sought Proof, Found and Almost Lost
When a German retiree proved a famous long-standing mathematical conjecture, the response was underwhelming.
Physicists Attack Math’s $1,000,000 Question
Physicists are attempting to map the distribution of the prime numbers to the energy levels of a particular quantum system.
Quantum Questions Inspire New Math
In order to fully understand the quantum world, we may have to develop a new realm of mathematics.
A New Blast May Have Forged Cosmic Gold
For decades, researchers believed that violent supernovas forged gold and other heavy elements. But many now argue for a different cosmic quarry.
