Answer 2

that is an enormous question that even renowned physicists have themselves repeatedly asked. some say it isn't a theory at all...that its more a philosophy than a theory. they say this because, thus far, no one has come up with an experiment to test it...until it can be tested, it is not a true theory in many minds.

that being said...string "theory," or whatever, says that the fundamental particle of our universe is a one-dimensional vibrating string of energy, where the vibrating frequency (energy level) determines what that string is in our real-world, 4 D world (including time as the fourth D). thus, depending on the vibration frequency, strings look like gravity, light, magnetism, and some exotic atomic particles that I've long since forgotten.

Brian Greene is the best source I know of for the novice in string theory. There are also multiple sources on the web; just browse with "string theory," you may be surprised at the wealth of sources.

Answer 3

String theory states that : The tension in a string is directly proportional to the force applied on the string.

Answer 4

Can't push a string! Wait, that's a rope. Oh well should apply to strings too. Try it at home if your not convinved.

Answer 5

its a multi dimensional(10 - 26) theory of space and energy.Can get alot of detail on wikipedia - search string theory!
