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 ...

The universe began with a bang—an explosion so intense, it forged the fabric of space and time itself. This pivotal moment, known as the Big Bang, marked the birth of everything we see, know, and are.

This program was pioneered by Einstein, who lacked sufficient experimental information to achieve a unified field theory. Building on the lessons of the last 25 years we may now be on the verge of ...

Few fields of scientific endeavor are “hotter” than superstring theory. Despite a debate that has broken out between theoretical physicists over the substantiality of the field (see “Opinion,” page 9) ...

It's called superstring theory and it is, so far as I can see, totally divorced from experiment or observation. If not totally divorced, pretty well divorced. They will deny that, these string ...

Now there is no doubt that superstring theory, and its successor M-theory, are the dominant paradigms in current attempts to unify gravity and quantum mechanics and to explain all physical phenomena.

Moreover, the flowering of superstring theory in the 1980s and 1990s — in which the UV-divergence problems of gravity are cured by a completely different mechanism replacing the basic field ...

Officially known as "superstring theory," it differs from traditional physics, in which all matter is made up of ball-like particles. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other ...
