In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

String theory suggests that the most fundamental building blocks of the universe are not particles like electrons or quarks, ...

String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of ...

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?" Forty-five years later, ...

Our universe may be fundamentally unstable. In a flash, the vacuum of space-time may find a new ground state, triggering a cataclysmic transformation of the physics of the universe. Or not. A new ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, ...

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 ...

When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain. Ordinary matter, the stuff we can see and touch, accounts for just ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...
