Theory-Affirming Evidence About the Universe
Bill Kendrick writes "Astronomers using a radio telescope at the South Pole have recorded a flicker of light from nearly 14 billion years ago that verifies most modern theory about the cosmos. Way back then, light and matter were only just beginning to separate from each other."
Everyone knows the Universe is only 4000 years old :)

Way back then, light and matter were only just beginning to separate from each other
14 billion years ago, matter and light were inseperable. They went everywhere together. Friends cheerfully complemented them on their strong attachment to each other, but whispered behind their backs about 'co-dependency'.
Then, something happened. No one apart from a few math-sodden physics profs are quite sure what is was. Some say matter was too indecisive, today forming simple hydrogen isotopes, tomorrow churning out all sorts of unstable heavy metals. Others blame light for being too inflexible, not wanting to 'move too fast'.
Whatever the cause was, matter and light decided to separate. Matter moved on, churning out everything from noble gases to metals that explode in water, satisfying every creative urge. Light, the brighter of the two, contented to be always aglow, yet unafraid to reveal shadows when the opportunity arose.
The tragic part of the tale involves the unfortunate castoff children of the great breakup, as divorces are never easy on offspring. Cosmic ray wreaks havoc anywhere and everywhere. Cynical X-Ray prefers to reveal everything hidden, as if compensating for repressed emotion. Young microwave is communicative, but very hot under the collar, and don't even ask about Gamma ray. Maybe someday the children of the great breakup will work out their issues.
It's not the matter in the Universe which is "expanding", but the Universe itself. The Big Bang didn't happen at just one point in space; it happened at one point which became all of space. So the Big Bang happened everywhere - Kidderminster, Baghdad, Mercury, Andromeda, everywhere. So there are parts of the Universe which are very very far away from us. Light from these parts has travelled for billions of years to reach us, hence it was intially emitted a very long time ago, at a time just after the Big Bang.
Many people think the Big Bang theory means that the universe expands like a conventional explosion from a sigular point. This is not correct.
Imagine an infinite rubber sheet covered in dots. At the beginning of the universe (or as early as we can postulate) this sheet started stretching in all directions , so the dots on it became further apart. This is similar to what happened to the universe, except in the universe it was 3 dimentional. So there is no special place where the big bang happened, it was everywhere
Since the universe was always infinite and the big bang happened everywhere on the 'sheet', as we look further away we see further back in time. This means light is always coming from every age of the universe since the big bang for us to see. The light in this case came from when the 'sheet' stretched just enough for the density of the universe to allow light to pass freely without being continually absorbed and re-emitted. This is the base microwave background radiation.
This article is saying polarisation has been detected which means some evidence of the lights last scattering event is present, so this tells us something about the universe at the point when it became opaque to light.
I work at UChicago (Carlstrom, the professor here, is my advisor). For more information about CMB polarisation, I reccomend Wayne Hu's (a theorists) webpages at http://background.uchicago.edu.
He provides an excellent lay (and more complicated,
if you're interested) introduction to what's going on here.
Essentially, it boils down to the fact that people
have been looking for this phenomenon for 20 years, and if someone finally said conclusively, "It's not there" that means the last few decades of cosmology would literally have been back to the drawing board.
This really is an exciting timne in cosmology.
Nowhere in the Bible does it mention the Earth's age. Sure some Jews/Christians believe it was only 6000 years, but there are plenty of others (like myself) who believe in the Bible and still believe the earth is quite a bit older.
Anyway when I read this:
"when matter and light were only just beginning to separate from one another."
I thought of this:
Genesis 1:3 And God said, "Let there be light"; and there was light. 4 And God saw that the light was good; and God separated the light from the darkness.
I believe Genesis was inspired by God, but written though a person. I think the author of Genesis did a pretty good job trying to find words and descriptions for what they were shown.

This is really off-topic, but...
Yes, you're correct about Piltdown Man; he was a fraud perpetrated by a rather small group of British researchers (including, of all people, Arthur Conan Doyle.) He is mentioned in many scientific and literary works of the early 20th Century, including the stories of H.P. Lovecraft. It was a wildly successful piece of scientific trickery and deceit, perhaps the most successful hoax in history.
But here's the thing: it wasn't anti-evolution activists or Baptist ministers who exposed Piltdown as the fraud it was. The truth came out of a process that started at an international congress of paleontologists in 1953. That's right; the same scientific establishment that you are accusing of widespread fraud and corruption is responsible for learning the truth about Piltdown Man. Your mission, should you choose to accept it, is to find a biology textbook written any time after 1958 that mentions Piltdown Man in any context other than that he was a fraud. Find me a modern biology textbook that references Piltdown Man as evidence for evolutionary common descent.
Good luck.
Compare and contrast this with the creation science community. Many (but not all) of these folks consistently refer to theories and pieces of physical evidence that have long been debunked or shown to be fraudulent. Perhaps the most obvious example of this is references to the Paluxy River tracks, which some claim show human tracks next to dinosaur tracks, suggesting that man and dinos were contemporaries. This "evidence" was debunked a long time ago, and even the Institute for Creation Research, an organization not known for its strong committment to the scientific method, has suggested that "honest creation scientists" not use the Paluxy River tracks as evidence for a young Earth.
That's just one example of creationists providing false and/or debunked evidence for their particular brand of creationism. The list goes on and on; we've got ridiculous claims that evolution violates the 2nd law of thermodynamics, we've got the false stories about moon dust and about how NASA was afraid that Apollo 11 would get mired in it, we've got the urban legend about NASA computers "finding" the missing day from Joshua's siege on Jericho, etc. etc.
The point is this: Before you accuse scientists en masse of widespread fraud, lies, and deception, you might want to consider getting your own house in order first. The Piltdown Man debacle demonstrates that scientists are ever skeptical and are willing to admit when they are wrong and have been misled. Are you and yours capable of the same honesty?
We're going down, in a spiral to the ground
Oh boy another wonderful /. creationist-vs-evolutionist debate!
The experiment produced only about half the amino acids that are necessary for life.
But, there is no reason to doubt that the other amio acids can be similarly produced by non-miraculous means.
Non-organic reactions always produce left-handed and right-handed molecules in (roughly) equal amounts. However, only left-handed amino acids can be used in living cells.
Actually, as far as we can tell, life could exist using all right-handed amino acids also. It's quite possible that both types of life existed for a brief time, but one out-competed the other very early in earth's history.
The experiment succeeded in producing amino acids, but scientists have never been able to produce any more complex organic molecules in the lab. No DNA (not even fragments), no RNA, and certainly no proteins.
Current scientific thinking on the origin of life tends toward the idea that the earliest self-replicating molecules were simple peptides, chains of perhaps a couple dozen amino acids. Given that a lab experiment can form a bunch of amino acids in a few weeks, it's not that farfetched to imagine a chain of 30 or so to be spontaneously generated throughout the oceans of earth in a number of years.
Organic molecules tend to break down over time. This process is accelarated by water (didn't life supposedly form in the ocean?) and heat.
Last I heard, RNA is thought to have first been formed on catalytic clay substrates. But why would creation "scientists" bother to check the current theories when attacking straw men is so much easier?
No matter how many creationists point out their supposed "holes" in the mainstream scientific theories on the origins of life, they always fail to produce the one thing that would end the debate forever: ONE IOTA of SCIENTIFIC EVIDENCE that GOD EXISTS and that HE CREATED LIFE.
Until such time as this first piece of evidence is seen, why should the scientific community be expected to constantly defend the whole of mainstream geology, astronomy, and biology against attacks by creationists who have NO evidence supporting their own "theories", which are all based on a creation story the ancient Hebrews borrowed from the Sumerians and some unverifiable genealogies?
Hey kids, there's only 5 days left 'til Yak Shaving Day!
