Is a quasar thingy someone discovered.
It emited the light we saw 13.7 billion years ago (ish) meaning it emitted that light 770 million years after the big bang.
However, since we are seeing this 13.7 Billion years later. Does this mean that 770 million years into existence that the universe had already expanded 13.7 billion lightyears? Or was it closer, but expansion has made the gap bigger before the light could reach us?
Sorry, I'm not really sure what I'm asking myself. But every impulse in my body is screaming "this is wrong!" becuase I just can't understand how light can take 13.7 billion years to cross 770 million years distance
