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 ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

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 ...

Imagine a world unified by a single scientific principle, something that can explain life’s greatest mysteries, from the origin of space and time to gravity and smaller matters, like daydreams. Now ...

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

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 ...

Jason Lotay explains how mathematicians studying special geometries are collaborating with physicists to explore M-theory, an 11-dimensional description of the world that unifies the various string ...

Einstein introduced the cosmological constant to his equations of general relativity because he believed the universe was static. Faced with evidence that the universe was actually expanding, however, ...

Does string theory excite you? Mathematically, it holds up. Aspects about it suggest not one but several different dimensions, ones we're not generally privy to, though we may be interacting with some ...
