Well, according to the abstract: "The advanced civilizations may inhabit the interiors of supermassive black holes, being invisible from the outside and basking in the light of the central singularity and orbital photons."
It's easy to imagine that black holes gobble up everything they encounter, consigning this stuff to eternal oblivion. Right?
Well, not quite. Today, Vyacheslav Dokuchaev at the Institute for Nuclear Research of the Russian Academy of Sciences in Moscow points out that certain black holes can have a complex internal structure. And that this structure ought to allow photons, particles and perhaps even planets to orbit the central singularity without ever getting sucked all the way in.
A black hole is a region of space where gravity is so strong that nothing can escape, not even light. However, cosmologists have known for some time that there are regions inside charged, rotating black holes where objects such as photons can survive in stable periodic orbits.
