Or, is it?  The Subaru Telescope has captured about 1800 images of exploding stars, some 8 billion light years from Earth.  They say the distant universe is the early universe.  I once read that no matter where we are in the universe, we are at the center of the universe.  If that is true, then everyone in every part of the universe has a different "most distant".  There seems to be a fallacy somewhere here.  Perhaps in what shape we are giving the universe?

We have been told that we are living in an expanding universe which raises the question "what is the universe expanding into?"  I am sure I will be "corrected" shortly in the error of my ways, but from what I understand of inflation theory, the universe is expanding in all directions, which presumably would be a uniform expansion.  Assuming that the speed of light in a vacuum is constant, anything we observe that is farther away is also farther back in time.  The light from an object 8 billion light years away therefore should have left the source 8 billion years ago.  Logically the farther back in time we look the fewer objects there will have been to observe since they were still forming.  No matter how advanced our observational capabilities become, I don't believe we will ever be able to see the "Big Bang" or anything formed shortly thereafter.
