Cosmic strings vibrate much in the same way as a guitar string

String Theory supporters argue that the universe we live in has eleven dimensions, out of which three spacial dimensions and a temporal one, which define the void

and the space-time environment we experience daily. Some of you might say 'Well, the real world we live in has only four dimensions'. That may be true, but the concept of reality is rather strange, and states that the universe consists of anything that exists, does not exist and will exist.

For example, the Big Bang theory predicts there may be some areas of the universe that we may never see, as the space expands faster that the speed of light in relation to the observer, thus light from the respective area of space traveling for an infinite amount of time will never reach us. The fact that we cannot see an object outside the Hubble volume doesn't mean it does not exist, but the two systems are causally disconnected one from another.

String Theory predicts that the particles represented in the Standard Model as being point-like are actually more like strings of energy vibrating at different frequency which determines what type of particle it represents. Acoustics physicist Dr. Mark Lewney, in collaboration with rock guitarist Ibanez Sabre, recently released a book, called 'Rock in 11 dimensions: where physics and guitars collide', addressed to 14 to 16 year old students in order to explain String Theory, which currently promises to explain most of the mysteries of the Big Bang.

Dr. Lewney, is recognized as a physicist that often combines physics and rock music in order to explain physics aspects of guitar physics, and why not String Theory. Furthermore, the recently published book contains a brief introduction to the Large Hadron Collider, or LHC, which currently holds the record of the biggest particle collider ever built, and will become operational later this year.

While the LHC will provide with an image of the universe in the first seconds after the Big Bang that could explain the origin matter, and maybe reveal any 'hidden extra dimensions', Dr. Lewney is mostly interested in the examination of the fabric of space-time that poses some of the biggest mysteries along with the question where all the matter came from and, most important, where did it go?
