Dr Richard Battye from Manchester University and Jodrell Bank led our discussion on String Theory.

We have touched on String Theory in several topics in the past but this dealt with the basics of the theory itself. We are apparently not made of strings but merely of the vibrations of the string. We covered what is a “brane” and how strings relate to branes.

If we have no evidence that the theory is correct, why all the interest? What’s exciting about it is, if it’s right it solves a lot of very serious problems in physics – like reconciling gravity and quantum mechanics.

These strings are vibrating in 10 dimensions of which most are invisible.
