String theory suggests that the universe is far more complex than we ever imagined. What if the fabric of reality is woven ...

String theorists are betting that extra dimensions do indeed exist; in fact, the equations that describe superstring theory require a universe with no fewer than 10 dimensions. But even physicists ...

While still theoretical and highly debated, the mathematics of string theory suggests that there could be multiple dimensions of time. Columbia University's theoretical physicist Brian Greene ...

In the following interviews, read what seven physicists—some string theorists and some not—have to say about the theory and some of its more mind-bending components, such as extra dimensions ...

“String theory was developed for people to understand the physics of the strong interaction. [...] People started from a very ...

In order for that to work, string theory has to make one more radical assumption. That instead of living in a universe with three dimensions of space and one of time, we live in one with either 9 ...

Bootstrapping strings Evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering. (Courtesy: iStock/Anadmist) Striking ...
