How might black holes contain the universe's history?

Black holes may hold the entire history of the universe through their unique properties. Scientists believe that specific black holes, like Poehi, contain rings of light known as photon rings that function similar to frames in a movie, capturing the timeline of cosmic events throughout the visible universe's history. These photon rings essentially record and preserve information about the universe as it evolves. While black holes are typically known for their gravitational pull that prevents even light from escaping, this theory suggests they simultaneously act as cosmic record-keepers, storing the universe's secrets within their mysterious structures.
