For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and ...

Researchers at The University of South Carolina, USC, have proposed that a link between string field theory and quantum mechanics does exist. The link assumes that string field theory is a fully ...

Was the big bang really the beginning of time? or did the universe exist before then? Such a question seemed almost blasphemous only decades ago. Most cosmologists insisted that it simply made no ...

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. This insurmountable task has ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

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 ...

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...
