In the context of cosmology, the concept of a "baby universe" refers to a theoretical scenario where a new region of space-time is created through a quantum gravitational process.
These baby universes are considered unlikely to interact with their parent universes because the process involves the new region "budding off" and potentially disconnecting from the parent universe entirely. This separation creates a "tree" of universes, where the physical disconnection prevents interaction after their formation. It has been speculated that this process may occur within the interiors of black holes.1
