I don't know your problem now - but the universe is 13.8 billion years old and has a radius of 46.6 billion lightyears. So I would say a distance of 10 billion lightyears is equivalent to a time of 10/46.6*13.8 billion years in a cosmic context. Relativelly young, I would say.The iron atoms are 10 billion light years away ... how old does that make them? ...Nothing has been around 10 billion years. Everything would eventually wear down due to entropy. For example, our Earth's magnetic field could be gone in 500 years by one projection. That would be the end of all of us -- The Weakening of Earth’s Magnetic Field Has Greatly Accelerated, Could Have Apocalyptic Implications for All of Us - Global Research.
