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.

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

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.

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, 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 ...

String theory is a potential “theory of everything”, uniting all matter and forces in a single theoretical framework, which describes the fundamental level of the universe in terms of vibrating ...

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.

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 ...

Another possible test for string theory will be analyzing the detailed observations of the light left over from the Big Bang, called the cosmic microwave background radiation, which permeates space.
