摘要: We construct an instanton describing the pair production of non-Kaluza-Klein bubbles nothing in higher odd-dimensional de Sitter spaces. In addition to showing that higher-dimensional spaces have a nonzero probability become topologically nontrivial, this process provides direct evidence for association entropy with cosmological horizons as well are necessary ingredient string theory or any other consistent quantum gravity dimensions.
