It is fantastic that the farthest star detected is so far away: 12.9 billion light years. As a result, it is not the first star born in the Universe but it does predate the Sun by 7.9 billion years. Though this star is too short lived for life to evolve, but a dimmer star formed at the same time might have been the location of the first life in the universe. If that life evolved into intelligent civilization within 5 billion years (as it did here on Earth), that civilization would be 2.9 billion years old. What kind of civilization might it be?
Check out my article on the Kardashev scale to imagine the civilization that might be so incredibly old and associated with the farthest star. Could this end up being a class III galactic civilization? Maybe its only a class II stellar civilization? Or the civilization might have died out before it reached class I. The questions abound regarding such a civilization.
Science and science fiction are intertwined. Science does not rule out the fantastic. The universe we live in works according to science, but I find it fantastic.
