String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

Theoretical physicist Michio Kaku explains why he thinks string theory is the best way to understand how the universe works.

Alongside string theory’s explanation of the generation of subatomic particles is another idea often found in science-fiction novels: the concept of extra dimensions.

Then there is string theory's simple central, and oft-repeated, concept — that the spectrum of subatomic particles can be imagined as strings vibrating at different frequencies, like the notes ...

String theory - a simple way to understand the universe Theoretical physicist Michio Kaku explains why he thinks string theory is the best way to understand how the universe works.

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 ...

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 ...

Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles—though not yet those of our universe.

One aspect of string theory that riles many is that many versions of it require the universe to contain more than the three dimensions of space and one of time that we are familiar with.
