How might black holes serve as records of the universe's history?

According to a report in New Scientist, black holes may contain historical records through rings of light trapped in their orbits. Scientists compare these photon rings to tree rings or film frames, suggesting they store the entire history of the universe. Researchers believe these rings capture and preserve information about cosmic events over time. This perspective positions black holes as crucial pieces in the cosmic puzzle, containing valuable historical data despite their mysterious nature. The trapped light rings could potentially serve as a repository of universal history, offering insights into the evolution of space and time that scientists are still working to understand and access.
