Steps toward Quantum Gravity in a Realistic Cosmos

Jordan Cotler –  

Theorists have modeled an expanding spacetime—akin to our Universe—by taking inspiration from a string theory framework in which spacetime is emergent.   Read More »

A Way to Experimentally Test String Theory’s “Fuzzball” Prediction

Simulations reveal the gravitational-wave signal of string theory’s “fuzzy” black holes, a signature that researchers could potentially measure.   Read More »

A Microscopic Account of Black Hole Entropy

Leopoldo A. Pando Zayas –  

String theory provides a microscopic description of the entropy of certain theoretical black holes—an important step toward understanding black hole thermodynamics.   Read More »

Cosmic Predictions from the String Swampland

For more than a decade, string theorists have been trying to distinguish good models from so-called “swampland” models that are inconsistent with gravity. This sorting effort has led to testable predictions about dark energy.   Read More »

Out of Bounds

Liquids that approach an often-quoted lower limit for viscosity are deemed “perfect,” but now this lower limit is itself being questioned.   Read More »

Gravitational Theory Reproduces Superconducting Circuitry

Theorists created a gravitational model that is mathematically analogous to one for a standard superconducting device, extending the ways that the tools of general relativity can lead to insights into condensed matter physics.   Read More »

In pursuit of a nameless metal

John McGreevy –  

Although theoretical approaches to modeling “strange metals,” such as the cuprate superconductors, originate from apparently different sources, research now suggests they flow toward a single universal model.   Read More »

The weak and strong ends of a theory

Joseph Minahan –  

A mathematical formulism makes a step forward in proving the AdS/CFT correspondence that connects quantum mechanics with gravity.   Read More »
