New Scientist: Every black hole may hold a hidden universe.
“How would we know if we are living inside a black hole? Well, a spinning black hole would have imparted some spin to the space-time inside it, and this should show up as a ‘preferred direction’ in our universe, says Poplawski. Such a preferred direction would result in the violation of a property of space-time called Lorentz symmetry, which links space and time.” Fodder for sci fi, certainly.
Comments:
True. How do we find a ‘fixed point’ that is free of black hole or universe spin-bias? Perhaps mathematics/physics has the answer.

If the cause of the spin is external to anything we can experimentally detect I find it difficult to see how such assertions can be part of any meaningful theorum.
