Astronomers Find an Old-Looking Galaxy In the Early Universe
schwit1 tips news that a team of astronomers has studied one of the most distant galaxies ever observed and found puzzling results. The light we're seeing from this galaxy comes from roughly 700 million years after the Big Bang, so on the cosmic scale, it's quite young. But the galaxy appears much older than astronomers expected. Their paper was published today in Nature.
At this age it would be expected to display a lack of heavier chemical elements — anything heavier than hydrogen and helium, defined in astronomy as metals. These are produced in the bellies of stars and scattered far and wide once the stars explode or otherwise perish. This process needs to be repeated for many stellar generations to produce a significant abundance of the heavier elements such as carbon, oxygen and nitrogen. Surprisingly, the galaxy A1689-zD1 seemed to be emitting a lot of radiation in the far infrared, indicating that it had already produced many of its stars and significant quantities of metals, and revealed that it not only contained dust, but had a dust-to-gas ratio that was similar to that of much more mature galaxies.
Uh no, the Big Bang explains the ratios of hydrogen, helium and lithium in the observable universe. All the other elements were created when the first stars went supernova. That is rather the point of the nucleosynthesis line of evidence.

The Big Bang wasn't an explosion; it was a rapid expansion of all space. There is no center.

What do you think will happen when immensely more powerful space telescopes are launched?
They are going to find more and more distant stars.
There is no evidence that distant objects are younger objects, we see spiral armed galaxies (these require galactic collisions) at 13 B light years out and there are cosmic structures that take up a fair percent of the sky that could not have been formed quickly, maybe not even in 13 B years and certainly at vast distances not in 1 or 2 billion years.
The CMB does not match a perfect black body, the perfect black body chart is and the CMB chart use different scales. Notice this is http://en.wikipedia.org/wiki/C... is in frequency and this is in wavelength http://en.wikipedia.org/wiki/B... --- those are opposite units of measurements.
The Big Bang was an idea from 1920s before the modern era of space telescopes. The Catholic Church jumped onto the Big Bang in the 1950s because it aligns with the idea of divine creation and to atone of the treatment of Galileo, etc.
The Big Bang is going to join geocentrism as one of those funny beliefs humans had in early days of science, although it might take 20 years or so.

The "dark" stuff is essentially a placeholder, its a different way of saying "we don't have the foggiest what is going on heree".
