Comment They are getting older (Score 2) 17
It seems that 'the earliest Black Holes' (as observed by our increasingky accurate telescopes) are getting older and older, but are they really?
For extremely distant objects we rely on the Red Shift to calculate the distance (and therefore age)
But large black holes also have extreme gravity to incease the red shift of radia.ted electromagnetic waves.
In fact by definition the red shift of something at the event horizon is infinite.
Maybe we should take those 'age' indications with a grain of salt, especially as Sodium and Chlorine haven't had time to be fused yet.
