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 ...

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 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, ...

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 ...
