“Advanced civilizations may live safely inside the supermassive black holes in the galactic nuclei without being visible from the outside,” he says.
Such a civilization would be subject to huge tidal forces and energy density that builds up in these stable orbits as photons become trapped. There’s also the problem of causality violations, which some cosmologists predict would afflict this kind of weird space-time.
My brain. It is in love.
What is a causality violation, and can I keep one as a pet?
OH GO ON TALKING DIRTY TO ME.
“One of the problems that would at first seem to negate any chance of planetary orbits inside a black hole is that inside the event horizon of a black hole, radial dimension becomes time-like, rather than space-like. Conventional orbits are clearly impossible. But further in there is another horizon where the dimensions switch back again (at least, inside charged and rotating black holes). This is the inner Cauchy horizon and it’s beyond here that Dokuchaev says the interesting orbits for massive planets exist.” !!
