The invisible string theory went viral on TikTok in 2023, but has been around for years. Here’s everything to know about the invisible string theory.

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

The answer, dear multi-dimensional bundles of vibrating string, lie as much in our selves as in our stars. It’s not just that the math of string theory is complex, though it certainly is.

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.

String theory might be the theory of everything… or a flawed framework for theoretical physics.

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 ...

The theory failed to unite gravity and quantum mechanics. But it still has become one of the most useful tools in science.

Tests are possible If string theory is correct, fundamental particles of nature would not be the zero-dimensional pointlike objects of standard theory.

If string theorists can show that their framework is the only consistent theory of quantum gravity, does that make it true even without tangible evidence?

The physicist-mathematician Miranda Cheng is working to harness a mysterious connection between string theory, algebra, and number theory.
