LHC Spies Hints of Infant Universe
techbeat writes "The big bang machine may already be living up to its nickname, writes New Scientist. Researchers on the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider near Geneva, Switzerland, have seen hints of what may be the hot, dense state of matter thought to have filled the universe in its first nanoseconds."

They have spied indications of conditions such as those postulated to exist during the beginning of OUR universe.
Sadly, they have NOT seen indications of a NEW infant universe.
Didn't they tally up the numbers in 1650. So it's at LEAST 6360 years old now.
Usher published his calculation the late 1648. Note that he gives the initial date of creation as 4004 BC, Sunday October 23rd. That makes the current year 6014. However, he's not the first person to make such a calculation. The traditional Jewish calendar which has been used for about 1500 years at minimum, puts the current year as 5771 since creation. Some Christian denominations with literalist leanings have gotten other numbers as well. In general, a literal reading of the Bible gets you an age somewhere between 5400 and 7000 or so but the exact time span is complicated. For example, the book of Judges has irregularities and vague parts so working out how much time it is supposed to be is difficult (most likely Judges is a compilation of different stories from each of the tribes in the pre-monarchical period that then became ascribed to leaders of the united tribes. Some of the stories in Judges explicitly have leaders who only control a handful of the Twelve tribes). There are other issues. For example, the sections in Kings and Chronicles have different chronologies, giving different lengths of reign for some kings. Also, working out the chronology from the end of the First Kingdom to the middle of the Second Kingdom is frat with difficulties, including serious contradictions between the Biblical text and other extant texts from that time period. This is annoying to not just Biblical literalists but also historians and archaeologists.
It's called "asymptotic freedom".
In a QGP, for the time and distance scales in question (very short and very small), a quark can act as though it is free to move, like a dog on a rope in the yard - as long as it doesn't go very far, it can move freely without the rope (a string of gluons) yanking it around. Since the density of the QGP is very high, just being able to roam his yard is enough - there's plenty of things to chase/bark at/hump in his yard, he doesn't NEED to go beyond it, and his rope doesn't change his behavior.
However, as the QGP cools and expands, all the good stuff leaves the yard, and poor ol' DownBoy can't get at anything without running into the end of his rope.
So as long as all the neighborhood UpBitches, LeptonCats, W-kids, Z-leaves, and other things are squeezed into his yard, DownBoy has asymptotic freedom. Let things cool, and his gluon leash is cramping his style again.
