It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...

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 ...

For decades, scientists have theorized about what lies beyond the third dimension and if there can exist a unified theory to explain all of the workings of the universe. This insurmountable task has ...

String theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that ...

The belief that all physical matter is made up of vibrating "strings." For example, protons, electrons and neutrons are strings each with different vibrations. Officially known as "superstring theory, ...

String theory aims to explain all fundamental forces and particles in the universe—essentially, how the world operates on the smallest scales. Though it has not yet been experimentally verified, work ...

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a ...

Scientists have found what they say is a link between complex number theory and string theory. A mathematician and physicist working together found the connection, which they say is part of plotting ...

Note: For a definition of unfamiliar terms, see our glossary. The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters" of all ...

How long’s a piece of string? You may want to sit down for a minute. Gnu2000 String theory entered the public arena in 1988 when a BBC radio series Desperately Seeking Superstrings was broadcast.
