"We hypothesize that the advanced civilizations may live safely inside the supermassive black holes in the galactic nuclei being invisible from the outside, " according to Vyacheslav Dokuchaev --Moscow's Institute for Nuclear Research of the Russian Academy of Sciences.
The inner workings of these supermassive black holes may be less hostile than we realize, possibly with stable regions where life and even planets could exist, according to Russian cosmologist Vyacheslav Dokuchaev at Moscow's Institute for Nuclear Research of the Russian Academy of Sciences. Charged and rotating black holes have a complex internal structure that allow photons and particles of much greater magnitude to safely orbit the central singularity.
Dokuchaev's research demonstrates that "living inside the eternal black holes is possible in principle, if these black holes are rotating or charged and massive enough for weakening the tidal forces and radiation of gravitational waves to acceptable level." Type III advanced civilizations on the Kardashev scale that have achieved mastery of the resources of their galaxy, could inhabit such black hole interiors.
Sometimes we think we're so smart, because we have all these great tools, but we only understand four percent. That's not good. Dark energy has shaped the history of the universe ever since the Big Bang, and if we want to understand the history of the universe, how it evolved and where it's going from here, dark energy plays a big role in that.
