In the maximally extended Kerr spacetime (a rotating black hole), light rays have been discovered that pass through both horizons and the ring singularity, connecting our region to another asymptotically flat universe. A special parameter zone has been identified — the 'inner throat,' where photons have no turning points, and forbidden polar angles that restrict the reach of a distant observer. Analytical and numerical solutions in Eddington–Finkelstein coordinates refine previous formulas. Simulations for an observer in the negative r-region show strong distortion and inversion of the image, echoing the optics of white holes.
An ordinary black hole is a trap from which nothing escapes. But a rotating black hole is structured differently: at its center is not a point, but a ring of infinitely compressed matter. Space here is curved to the limit, and light rays trace unimaginable loops.
New research has revealed: thin beams of light slip through this ring, like a thread through a needle's eye. The slightest miss and the beam perishes, but a precise hit carries it into a mirror-reflected universe with inverted laws. From there, our sky would appear upside-down and distorted.
And so, information that falls into a black hole may not be lost, but seeps through the ring into another world.
🎯 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'.
