But he added that the European research was "not as secure as the measurements made with the Hubble."Freudian slip, perhaps? ;)

Most Distant Galaxy in Universe Detected Wow! Really? Now all we have to do is peek to the other side of that galaxy, and we'll get to see what's at the end of the universe. I guess there's nothing left in space to explore, then.

OK, somebody help me understand this. If this galaxy is 13.23 billion light-years from Earth and everything started with the big bang, which means everything started in the same place. Then if this galaxy went the opposite direction from the milkyway, why does it only look 2 billion years old and not 26.46 billion years old. How did we get way over here and still see this far galaxy as it was 13.23 billion years ago. Any reasonable explanation will be appreciated.

it's red shift?
(total shot in the dark)
To: Licensed-To-Carry
Because you're assuming the Milky Way galaxy is at the opposite end of the observed universe?
There's a big IF embedded in your question.
To: Licensed-To-Carry
Because of time dilation. This distant galaxy is travelling at close to the speed of light (in our reference frame). From our point of view, time is moving more slowly there.
To: Licensed-To-Carry
The galaxy didn't go the opposite direction from the milky way, I don't recall that being stated in the article.
However, you would be correct as far as a galaxy that expanded in the opposite direction as the milky way, as far as I understand. A galaxy that is today 13.23 billion light years from the center of the universe, if we were also 13.23 billion light years away from center in the opposite direction, would look 26.46 billion years old. That light being emmitted from that galaxy this instant, however, will take an additional 26.46 billion years before we actually observe it.
We cannot see to the origin of the universe, or the big bang, with current astronomy. This galaxy is young, but we are still magnitudes of magnification (boy that sounds funny) away from doing so if it is indeed possible and the big bang exists.

believed to have started with the Big Bang some 13.7 billion years agoWhat if they find a galaxy 13.8 billion light years away?

So, assuming it is moving away from us at "close" to the speed of light; what we have seen is purely a "marker" in time of where it "was". Now it is 90%+ further away (image we just saw was speed of light to us; it'speed, close to speed of light away from us;)? Can calculations be made to determine it's "now" distance away from us?

But I have heard the big bang described as being like a balloon being blown up. There are dots on the deflated balloon which represent galaxies but when the balloon is inflated the dots all rush away from each other at the same speed. So why does the observation of far off galaxies not reflect them as being even more distant. It's like the milky way expanded much faster than these other objects. I don't see how they can still reflect their youthfull appearance. Is it possible to see them in multiple places? Like 2 billion then 4 then 6 then 8 billions years away.

You know what, this is really beyond my realm of understanding. I understand the expansion of the universe (ala big bang theory) and all that jazz, but when time dilation and all of that is thrown in, things just get wishy washy in my mind. (though this won't be true for long as soon as I take my next physics course) Actually, now that I think of it, this is more of a question for
www.physicsforums.com. I'm sure that there are plenty of people there capable of providing insight.

The most important question.

Actually it's based on the book "The Elegant Universe."
Which is great. Only didn't understand about 10% of it (The parts about wrapped strings around cylinders and such) While I already basically understood relativity he explained portions of it in a totally new and neat way.

Light travels at a finite speed. So it takes time for light from that youthful galaxy on another part of the "balloon" to reach our galaxy. And while it's catching up with us, the balloon keeps expanding, and our galaxy is getting older and older. Finally, the light reaches us, and we see a still-young galaxy. If you want to see it when it's "our age", just keep watching and waiting, and be very patient, and live for a very long time.
