interesting (& perplexing) problem there...
since we can only 'observe' some ~13-14 billion light-years out in any direction...
then
that is the observable size of the universe
the ~46 billion light-year model is an acadmic exercise, a model adapted to our comprehension.
for instance, a being living on a planet of that dwarf & light-weight galaxy
the scientists have discovered...would have the same ~13-14 billion-light-year horizon
that we presently have here on earth.
But their view of of their observable universe would include a volume of sky that would remain unseen from earth, because they are 6 bly distant
their 'horizon' would different in the direction exactly opposite the
earth-dwarf galaxy alignment
the new - "looking from above madel" - of the observable universe
from 2 points in space (here & there) would make the universe have the shape of an ellipse...some 52 billion light-years large, 'in theory'
but in practicality, the observable universe is only ~13-14 bly large, from any observation point at any one time
boggling!
Do they mean half way across the "known" universe?
