String theory is an attempt to unite the two pillars of 20th century physics — quantum mechanics and Albert Einstein's theory of relativity — with an overarching framework that can explain all ...

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

The five main string-theory candidates may all just be pieces of a larger, cohesive whole — and M-theory could bring them together.

String Theory 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.

In the 2000s, string theorists realized that the theory's equations do not describe a single universe but a staggering number of 10 500 possible solutions. Each of these solutions corresponds to a ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted ...

Before I explain the significance of Smolin’s conclusion, it is important to understand what string theory is, what problems it is attempting to solve and why, in Smolin’s view, it has failed.

String theory was formulated in the late 1960s to explain certain features of the strong nuclear force, one of four fundamental forces of nature.

The reason strings are such a hot topic nowadays, Jones explains, is that the new theory not only helps to solve some long-standing problems in physics, but it also attempts to explain other, not ...

However, for more than 40 years now, there has never been found a single piece of experimental data that can only be explained by string theory. String theory cannot explain anything better than the ...
