Supermassive rotating black holes could be portals: a beam of light slips through the ring singularity into a mirror universe. This explains white holes — inverted black holes. Scientists have shown that the view from there is a distorted, upside-down sky.
🎯 The central ring of a rotating black hole is like a needle's eye: the slightest miss dooms a falling object, but a perfect hit ejects it into a mirror universe.
🎬 Passing through a rotating black hole into another universe echoes the wormhole concept shown in the movie 'Interstellar'.
