Can anyone explain to me what 'string theory' is?

I know this is a stupid question, but I've heard about string theory many times, but have no clue what it really is. Please understand I have very little background in physic. Do you have a good explanation about what it is and why it matters a lot in our universe? Thanks!

  • May 24 2012: Hi Felippa, String theory is one attempt to explain how matter gets its properties such as mass and gravity. It does this by attributing each known particle as if it were a string vibrating in different frequencies such that each vibration frequency ties in to a certain characteristic of the particle. No question is stupid!
