Abstract: (Elsevier)
It has been pointed out that the universe may contain Schwarzschild wormholes produced by first-order phase transitions of a vacuum. In this letter, we consider this possibility for the more general case in which the vacuum energy density inside growing bubbles remains finite. We show that (1) Schwarzschild-de Sitter wormholes are created instead of simple Schwarzschild ones, and (2) if the remaining vacuum energy density is greater than a critical value, no wormholes are created.- ASTROPHYSICS
