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

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

The Standard Model of our universe doesn’t match the evidence, in part because of dark energy, a ghostly force pushing the ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only a sliver of reality. Extra dimensions, if they exist, would not just be a ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

Most people are perfectly content with three dimensions to carry out daily tasks -- or four if they take time into account. String theorists, on the other hand, think that many more dimensions are ...

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 ...
