This also means that there could be hidden curvatures of space-time or gravitational fields, which could explain a ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

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 ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

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 ...

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 ...

At the Large Hadron Collider in Europe, the discovery of the century could start with nothing. When physicists begin smashing protons together at unprecedented energies over the next year, they will ...

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 ...
