The universe feels three-dimensional — but some of the deepest physics suggests reality may have 11 dimensions hidden from our senses. This idea comes from theories like string theory and M-theory, ...

A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

Tiny little threads whizzing through spacetime and vibrating incessantly: this is roughly how you can imagine the universe, according to string theory. The various vibrations of the threads generate ...

For decades, scientists have taken issue with “string theory” — a theory of the universe which contends that the fundamental forces and matter of nature can be reduced to tiny one-dimensional ...

Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of the ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...
