- The set of all possible string theories
Extensive Definition
Recent developments in string theory suggest that
the string
theory landscape of vacua is vast. It is natural to ask if this
landscape is as vast as allowed by consistent-looking effective
field
theories. Some authors (like Cumrun Vafa)
suggest that this is not the case, and that the landscape is
surrounded by an even more vast swampland of consistent-looking
semiclassical
effective field theories, which are actually inconsistent.
