Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

Here’s what you’ll learn when you read this story: String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to ...

Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, ...

For decades, physicists have chased the dream of unifying all of nature’s forces under a single theory. String theory has long been a top candidate, offering a single mathematical framework that could ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

CERN’s calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility of new physics. Particle’s surprise mass threatens to upend the standard ...

The Theoretical Advanced Study Institute in Elementary Particle Physics (TASI) recently concluded its 40th year, bringing 65 students from around the world to Boulder to delve into the “Frontiers of ...
