Scientists studying the deepest picture of the Universe, taken by the Hubble Space Telescope, have been left with a big poser: where are all the stars? The Ultra Deep Field is a view of one patch of sky built from 800 exposures.
The picture shows faint galaxies whose stars were shining just a few hundred million years after the Big Bang.
"Our results based on the Ultra Deep Field are very intriguing and quite a puzzle," says Dr Andrew Bunker, of Exeter University, UK, who led a team studying the new data."
"They're certainly not what I expected, nor what most of the theorists in astrophysics expected."
"There is not enough activity to explain the re-ionisation of the Universe," Dr Bunker told the BBC. "Perhaps there was more action in terms of star formation even earlier in the history of the Universe - that's one possibility.
"Another exciting possibility is that physics was very different in the early Universe; our understanding of the recipe stars obey when they form is flawed."

IS HE 01075240 A PRIMORDIAL STAR? THE CHARACTERISTICS OF EXTREMELY METAL-POOR CARBON-RICH STARS
[Snip from Hugh Ross' Site, RTB.org]
Astronomers in Japan may have found a significant piece of evidence for the big bang creation event. Their measurements on the star HE 0107-5240, the most iron-poor star yet observed, show that it may indeed be one of the long-sought first generation stars predicted by the hot big bang creation model. The big bang model predicts that virtually all first generation stars would be very massive and, thus, would have burned out some 13.5 billion years ago. These stars would be undetectable today, though a small first generation star can burn long enough to still be visible. However, such a star takes so long to form that some of the gas from which it accretes gets polluted by the ejecta from the supernova eruptions of the much larger first generation stars. The Japanese team showed that HE 0107-5240 has the chemical signature of such pollution and probably is indeed a first generation star. Future measurements, soon to be performed, will permit a definitive conclusion.

Isn't it easier for you to imagine a poured concrete wall, spray painted with flat-black paint, than to imagine a picture that exists, on and on, and on & never, ever ends.
Damn thing about it, though, something has to be on the other side of the poured concrete wall.
Infinite is just hard to comprehend, just as it would be to live forever.
