Researchers use the S-matrix bootstrap to examine whether string theory is the only consistent theory of quantum gravity
The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few decades, some physicists have ...
String theory solves mystery about how particles behave outside a black hole photon sphere
A paper by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Director Ooguri Hirosi and Project Researcher Matthew Dodelson on the string theoretical effects outside the black hole photon sphere ...

Mathematicians unravel a thread of string theory
Simply put, string theory is a proposed method of explaining everything. Actually, there's nothing simple about it. String theory is a theoretical framework from physics that describes one-dimensional, vibrating fibrous objects ...

Chandra data tests 'theory of everything'
One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably the best-known proposal for a "theory of everything" that ...

Researchers uncover an anomaly in the electromagnetic duality of Maxwell Theory
Researchers at the Kavli Institute for the Physics and Mathematics of the Universe (WPI) and Tohoku University in Japan have recently identified an anomaly in the electromagnetic duality of Maxwell Theory. This anomaly, outlined ...
Researchers propose new holographic method to simulate black holes with tabletop experiment
A research team from Osaka University, Nihon University and Chuo University has proposed a novel theoretical framework whose experiment could be performed in a laboratory to better understand the physics of black holes. This ...

Dark energy vs. modified gravity: Which one will prevail?
Einstein's theory of general relativity predicts the existence of dark energy—a mysterious form of energy that permeates space and accelerates the expansion of the Universe. But what if Einstein was wrong and there was ...
