A theory of everything?

“String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.”

Edward Witten

The strangeness of quantum mechanics were explored by various physicists whom explained the quantum interactions in terms of exchanging ‘virtual’ particles. More subatomic particles emerged of the collisions of other particles. The standard model of particle physics emerges from the fundamental particles of nature according to their properties.

There is a search for the theory of everything – a theory that would unite all four fundamental forces of nature.

Deep puzzles remain to be solved and a theory that would unite quantum mechanics with general relativity.

String Theory

An idea of tiny vibrating strings that makes up our entire universe is quite remarkable. Think of the universe as it is made up of tiny strings of energy and not point like figures. Waves of vibrations found within the strings give rise to quantized behavior that is described as nature.

(String theory will be explained in the next entry.)

“If string theory is a mistake, it is not a trivial mistake. It is a deep mistake and therefore kind of worthy.”

Lee Smolin
