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

Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the ...

Since the 1980s, string theory has emerged as the leading candidate for achieving every physicist’s dream: reconciling general relativity with quantum mechanics and thereby finding a tidy ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial ...

String theory remains our best candidate for a theory of everything, but where can it be tested? By studying black holes, says Marika Taylor.

An idea derived from string theory suggests that dark matter is hidden in an as-yet-unseen extra dimension. Scientists are racing to test the theory to see if it holds up.
