Aliens hide in black holes

The discovery of stable orbits inside certain kinds of black hole implies that planets and perhaps even life could survive inside these weird objects, says one cosmologist.

He calculates that the stable orbits are nonequatorial and have a rich structure (see picture). They would also be brightly illuminated by the central singularity and by photons trapped in the same orbit.

That raises an interesting question: whether a planet in such an orbit could support a complex chemistry that is rich enough to allow life to evolve.

Dokuchaev clearly thinks so. "Advanced civilizations may live safely inside the supermassive BHs in the galactic nuclei without being visible from the outside," he says, somewhat speculatively.

Of course, such a civilisation would have to cope with extraordinary conditions such as huge tidal forces and the huge energy density that builds up in these stable orbits as photons become trapped. There's also the small problem of causality violations, which some cosmologists predict would plague this kind of tortured space-time.

Ah, nothing like using the irresponsible tactic of stating something that is speculative as fact to make Asterisk feel just like the neighborhood grocery store check-out line!

Arxiv submission was on time though.
