Where Gravity Is Weak and Naked Singularities Are Verboten
The British physicist and mathematician Sir Roger Penrose conjectured in 1969 that visible or “naked” singularities are actually forbidden from forming in nature, in a kind of cosmic censorship. But why should quantum gravity censor itself?
Dark Matter Recipe Calls for One Part Superfluid
A different kind of dark matter could help to resolve an old celestial conundrum.
Wanted: More Data, the Dirtier the Better
The computational immunologist Purvesh Khatri embraces messy data as a way to capture the messiness of disease. As a result, he’s making elusive genomic discoveries.
A Theory of Reality as More Than the Sum of Its Parts
New math shows how, contrary to conventional scientific wisdom, conscious beings and other macroscopic entities might have greater influence over the future than does the sum of their microscopic components.
The Thoughts of a Spiderweb
Spiders appear to offload cognitive tasks to their webs, making them one of a number of species with a mind that isn’t fully confined within the head.
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.
