If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

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 ...

Japanese physicists have created a string theory model that simulates the birth of the universe. In their model, the Big Bang was a "symmetry-breaking event" — a fluctuation that caused three spatial ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of Your Place in the Universe. String theory is a hypothetical ...

What is string theory: It replaces point-like particles with tiny vibrating strings, requiring extra dimensions to reconcile gravity with quantum mechanics. Why it matters: String theory could unify ...
