title = "Child universe production",
abstract = "There are solutions of Israel junction conditions that describe the detachment of a region of spacetime, a bubble, from what can be called the parent spacetime. In the past these solutions have been mostly considered in the context of inflationary cosmology (the so called baby universes). We will i) briefly review these ideas, ii) show that they can be of interest under more general settings and iii) present solutions where it is possible to create a universe at arbitrarily small energy cost. This could have interesting applications for quantum gravity and particle physics, besides cosmology.",
