Unraveling of the extra dimensions?

  1. Jun 29, 2008 #1
    I read somewhere that string theory could be disproved if it is found out that the universe expanded at a certain speed as this would cause the extra dimensions to unravel and therefore mean that string theory could not describe our universe. I do not understand why the extra dimensions would unravel? Can anyone help?

    Many Thanks,
