The ScienceDaily article Our Universe at Home Within a Larger Universe? So Suggests Physicist’s Wormhole Research said

Could our universe be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe?
 
Such a scenario in which the universe is born from inside a wormhole (also called an Einstein-Rosen Bridge) is suggested in a paper from Indiana University theoretical physicist Nikodem Poplawski in Physics Letters B.
 
Poplawski takes advantage of the Euclidean-based coordinate system called isotropic coordinates to describe the gravitational field of a black hole and to model the radial geodesic motion of a massive particle into a black hole.
