The universe feels three-dimensional — but some of the deepest physics suggests reality may have 11 dimensions hidden from our senses. This idea comes from theories like string theory and M-theory, ...

A new study just added an interesting twist to the complicated history of the physics theory.

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

What if reality is more than we can perceive? Scientists believe the universe may have 11 dimensions, shaping the very fabric of existence! Learn how string theory and higher dimensions could explain ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

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

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 ...

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 ...
