Brian Greene explains the basic idea of string theory in under three minutes.
String theory aims to incorporate all four of nature's fundamental forces into a single quantum mechanical framework. These four forces are:
By modeling subatomic particles as tiny, vibrating one-dimensional strings rather than zero-dimensional points, the theory seeks to provide a unified field theory that reconciles quantum mechanics with general relativity. While it remains a promising mathematical construct for describing all physical phenomena, it is currently an untested hypothesis that has yet to be confirmed by experimental observation.12
