Farthest Bang: A burst that goes the distance
The most-distant gamma-ray burst ever found hails
from 900 million years after the birth of the universe,
around the time when stars and galaxies first flooded
the universe with light.

Is this just within, or just on the other side of the causal
horizon?????
***********
http://www.nap.edu/readingroom/books/cosmology/1.html
The edge of the accessible universe is the causal horizon, a spherical
boundary centered on Earth with a radius of about 15 billion
light-years (the speed of light the age of the universe). Information
from beyond the causal horizon cannot reach us because there has not
been enough time since the Big Bang for any signal to travel so far,
even at the speed of light. But as the universe gets older, the horizon
moves out, bringing more of the unseen universe into view. What is the
nature of the "stuff" beyond the horizon? Lacking information and an
adequate physical theory of the Big Bang itself, cosmologists can only
speculate. Observers on a galaxy a billion light-years away from the
Earth could draw a similar causal horizon around themselves, but their
horizon would include parts of the universe that astronomers on Earth
would not be able to see. Given the assumption that observers see a
similar universe regardless of where they are, the part that we call
unseen must be similar to the part just inside our horizon. From this
argument cosmologists conclude that the part of the universe we can see
is embedded in a much larger universe of the same stuff, possibly
extending to infinity, or possibly not.

And where does that leave you, and all other BB and GR
worshippers???????
Something which utterely contradicts the possibility of both being
correct (very old "happenings/objects at large distance),
hereby paints you as a gullible disciple of the first order.

Explain sound to the born deaf?
Colour to the blind?
That takes a recipient of the explanation who has an open and seeking
mind.
Ignorance is bliss, so smile on.

Einstein Year - a year celebrating physics - Special Relativity
http://www.einsteinyear.org/facts/special_relativity/fact_view
It is not surprising that relativity is hard to understand and
even to believe - it goes against our everyday experiences. But
relativity has stood the test of time, and like it or not, the
universe really is this strange.
