Swampland Revisited

Abstract The transcendental expectation of string theory is that the nature fundamental forces, particle spectra and masses, together with coupling constants, uniquely determined by mathematical logical consistency, non-empirically, pure reason. However pluralism triumphed explosive emergence multiverse. String theorists have extended a long-sought dream (their unique final theory) to landscape or happy caparnaum. Proponents try qualify their arguments via swampland conjectures while cosmologists retreat telescopes. We review current status swampland.
