Some see string theory as the one great hope for a theory of everything – that it will unite quantum mechanics and gravity and so unify all of physics into one glorious theory.

Are Virtual Particles A New Layer of Reality?

Why has string theory been the obsession of a generation of theoretical physicists? What exactly is so compelling about tiny, vibrating strings? In our last string theory episode I talked about what these things really are, and covered some history. In short: the strings of string theory are literal strands and loops that vibrate with standing waves. Simply by changing the vibrational mode you get different particles – analogous to how different vibrational modes on guitar strings gives different notes. And, by the way, strings exist in 6 compact spatial dimensions on top of the familiar 3.
