How might black holes contain a record of the universe's history?

According to scientists, the rings of light (photons) trapped in a black hole's orbit may serve as a historical record of the cosmos. Specifically, the black hole Poehi is described as a repository of universal history, with these photon rings being compared to tree rings or film frames that store historical information. Scientists believe these orbiting light structures could contain the entire timeline of the universe's past, making black holes not just destructive entities but also cosmic archives. While much of our knowledge about black holes remains theoretical due to their immense gravitational pull, these photon rings potentially offer unique insights into cosmic history.
