Spot on

exactly as I understood it. In the Foxtel show "Visions of the future", presented by Professor Kaku, he went on to say that this model will only work with this amount of dimensions- the others didn't cut it.
You would know this already, but for those who don't, the M theory name was invented by Witton and it stands for "magic".
Did you watch that series Craig? It was on recently. Brilliant!
