7 Megaparsecs black hole jet?

It appears that at least one black hole emitted 7 Megaparsec long jet structure (i.e. over 22 million light years) about 5 Gyr after the Big Bang (or about 9 billion years ago). That this jet structure is still visible today, is amazing. I wonder if black holes are effectively mini-Big Bangs and THE Big Bang is just a periodic singularity black hole that forms once in a while (as all previous black holes collapse into one).
