WebThe String Landscape and the Swampland Cumrun Vafa Jefferson Physical Laboratory, Harvard University Cambridge, MA 02138, USA Abstract Recent developments in string theory suggest that 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. WebString Theory is a supervillain imprisoned in the Birdcage.

WebDec 6, 2024 · In this article, we study the implications of string swampland criteria for dark energy in view of ongoing and future cosmological observations. If string theory should be the ultimate quantum gravity theory, there is evidence that exact de Sitter solutions with a positive cosmological constant cannot describe the fate of the late-time universe. Even … WebMay 10, 2024 · If the real world were to lie in the swampland, it might strongly suggest that either string theory itself or the swampland program is wrong. 1 This is a unique—although still intensively debated and clearly controversial—way of possibly falsifying a candidate theory of quantum gravity.
