Question: What is string theory

Erm, something to do with violins, violas, cellos, double basses, harps & guitars?!?!

Seriously, though, this is a bit beyond my area of expertise. It’s basically a mathematical model that people have created to try and explain the results from some experiments that have been done in quantum mechanics. I’m absolutely not going to pretend that I understand it, though, because I don’t!!
