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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit ...

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 ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a "provable" phenomenon. But a team of physicists has now taken a significant ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, ...

A detailed look at the Universe reveals that it's made of matter and not antimatter, that dark matter and dark energy are required, and that we don't know the origin of any of these mysteries. However ...

I am fine with there being extra dimensions - for example, I'd be happy to think of electrical charge as some property that is projected or emergent from some higher dimension (1) and I've always ...

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 ...
