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 ...

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 ...

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

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 ...

After 60 years, this beautiful theory hasn't produced many tangible results. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Paul M. Sutter is an ...

NOVA: What is so compelling about string theory to make you want to devote your career to it? Lykken: I think when a lot of people go into theoretical physics, they're looking for the big answers to ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

For more than a century, physicists have suspected that the familiar three dimensions of space might be only a small slice of reality. The idea that the universe could be hiding several additional ...

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 ...
