Science of another order

As a scientist, I spent my research career asking questions, designing experiments to answer those questions and then conducting the experiments. Finally, the results would be analyzed, conclusions would be made, and then published for others to consider.
Being retired, I often run across science which is asking questions I would never be able to even ask. Here is an example I ran across today in Science Daily.

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. The final version of the paper was available online March 29 and will be published in the journal edition April 12.

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.
