string theory

A possible way of resolving the greatest problem of physics.

If, as string theory suggests, the world is made of strings, then what does that mean for a geometry of points? Find out more in this video.

The holy grail for 21st century physics is to produce a unified theory of everything — M-theory is a prime candidate. Find out more in this video.

There are many theories in particle physics that cannot be tested in experiments. Does this make it unscientific? This debate, featuring one of our favourite theoretical physicists, David Tong, explores the question.

Could the world be simpler than our senses suggest?

"[String theory] has led us in strange directions that we couldn't conceive of; it's revealed depths of mathematical structure that we couldn't have anticipated". Watch a video interview with Professor Michael Green, winner of the 2014 Fundamental Physics Prize.
The fact that a sizeable proportion of the financial workforce is made up of physicists is one of the industry's best-kept secrets. We talk to Laura Tadrowski, who has made the leap from physics to finance.

How many dimensions are there? In the latest online poll of our Science fiction, science fact project you told us that you'd like an answer to this question. So we went to see theoretical physicist David Berman to find out more.
