Some see string theory as the one great hope for a theory of everything. Some see string theory as the one great hope for a theory of everything – that it will unite quantum mechanics and gravity and ...

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle, ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known universe. The ...
