At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

The final installment of a three-part NOVA series about "String Theory," a new branch of science that seeks to explain nothing less than how the universe works, airs on PBS. Ray Suarez speaks with ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

Scientists propose a link between string field theory and quantum mechanics that could open the door to using string field theory as the basis of all physics. Their calculations "could solve the ...

The most celebrated theory in modern physics faces increasing attacks from skeptics who fear it has lured a generation of researchers down an intellectual dead end. In its original, simplified form, ...

String theory, simultaneously one of the most promising and controversial ideas in modern physics, may be more capable of helping probe the inner workings of subatomic particles than was previously ...

Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

Was the big bang really the beginning of time? or did the universe exist before then? Such a question seemed almost blasphemous only decades ago. Most cosmologists insisted that it simply made no ...

Researchers at The University of South Carolina, USC, have proposed that a link between string field theory and quantum mechanics does exist. The link assumes that string field theory is a fully ...
