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

String compactification refers to the process of reducing the ten or eleven dimensions intrinsic to string or M-theory down to the four dimensions of observable spacetime by assuming that the extra ...

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 ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

String theory might be the theory of everything… or a flawed framework for theoretical physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

What is the stuff in the universe made of? Our high-school physics tells us atoms, with 90 natural elements building the world around us. But what are these atoms made of? Over the last century, we've ...
