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. Some theoreticians, tentatively suggest, swamp is not a mathematical theorem of superstring, or given rasing to the more fundamentally M-theories of tentative theoretical background, quantum or with a relativity remarkable spinor interchange (graviton).
