This sort of thing perplexes me.
They say the hubble deep field was the furthers we'e seen into the cosmos at an 11 day exposure 13 billion light years..
We see a field full of galaxies and yet...
They tell us they've seen beyond where galaxy formed...a hydrogen cloud from the begining that obscures our view. A bit confusing how they've seen these structures if the HUDF is the longest exposure to date.
