Gravity: A Theory in Crisis May 5, 2009 — Note: This is **not** a joke. How could gravity be a theory in crisis? Isn’t gravity one of the best-understood facts of nature? Don’t we all avoid jumping off cliffs because of the law of gravity? Gravity is doing just fine, thank you. It’s our theory of gravity, and the cosmology built on it, that is in crisis – according to a report on PhysOrg today: “Study plunges standard Theory of Cosmology into Crisis.”...

BRIAN GREENE spent a good part of the last decade extolling the virtues of string theory. He dreamed that one day it would provide physicists with a theory of everything that would describe our universe - ours and ours alone. His bestselling book The Elegant Universe eloquently captured the quest for this ultimate theory. "But the fly in the ointment was that string theory allowed for, in principle, many universes," says Greene, who is a theoretical physicist at Columbia University in New York. In other words, string theory seems equally capable of describing universes very different from ours. Greene hoped...

Science Still in the Dark about Dark Energy by Brian Thomas, M.S.* Evolutionary astronomers have a problem. The universe is expanding at an ever-increasing rate, but if general relativity is an accurate cosmological model, and if the universe is made up of the kinds of matter and energy that are directly detectable (like atoms and light), then its expansion should be slowing. Astronomers “fixed” this problem by theorizing that “75% of the energy density of the universe exists…as dark energy.”[1] This non-detectable dark energy allows the man-made model to match astronomical observations. However, scientists are aware that dark energy itself...

Is theoretical physics becoming the next battleground in the culture wars? Not according to some theologians and scientists.People have long sought after a theory of everything, even when they had nothing but their five senses as tools of measurement. In the 6th century BCE Thales asserted that all matter is made of water; Anaximenes responded that itÂ’s all air. Parmenides a century later concluded with exacting proofs that everything we see is an illusion and that reality really consists of a single, unchanging sphere. Today, scientists are once again looking beyond the pale of measurable time and space to answer...

Early Large Galaxies Stun CosmologistsApril 02, 2009 — Cosmology has a kind of Cambrian Explosion of its own to grapple with.  Contrary to expectations, some of the earliest galaxies appear as large as current ones, if not larger.  Astronomers, using the Subaru telescope in Hawaii, examined five galaxy clusters with ages estimated at 5 billion years after the Big Bang.  Statements in a report on this study in Nature News make it sound revolutionary: The findings could overturn existing models for the formation and evolution of galaxies that predict their slow and steady growth through mergers. They calculated the mass...

Does Dark Energy Really Exist? Or does Earth occupy a very unusual place in the universe? Scientific American, March 2009 By Timothy Clifton and Pedro G. Ferreira ... Most of us are very familiar with the idea that our planet is nothing more than a tiny speck orbiting a typical star, somewhere near the edge of an otherwise unnoteworthy galaxy. In the midst of a universe populated by billions of galaxies that stretch out to our cosmic horizon, we are led to believe that there is nothing special or unique about our location. But what is the evidence for this...

On March 16, 2009, the Templeton Foundation announced the winner of its annual 1 million pound sterling (1.42 million USD) prize, an amount that exceeds the payoff of the prestigious Nobel Prize...Dr. d’Espagnat was awarded the prize for his work using theoretical physics to predict the reality of a hypercosmic god, who exists outside of the physical universe...

Critics of the Bible have often said that the writings of Genesis reflect an “unscientific view” of the universe—one that reflected the cosmology of the ancient world. One of these criticisms centers on the Hebrew word raqia used in the creation account of Genesis 1. Several Bible versions, such as the New King James, translate this word as firmament: Genesis 1:6–8, NJKV Then God said, “Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.” Thus God made the firmament, and divided the waters which were under the firmament from...

God’s mighty expanse by D. Russell HumphreysPublished: 26 February 2009(GMT+10) Psalm 150:1, the first verse of the last psalm, contains a phrase that has always intrigued me: … Praise Him in his mighty expanse. (NAS), or… praise him in the firmament of his power. (KJV) God made the expanse (firmament) on the second day and called it “heavens” (Genesis 1:8, plural from literal Hebrew). Later, on the fourth day, He populated the expanse with the sun, moon and stars (Genesis 1:14-19). So the expanse is not the heavenly bodies, but rather the space that contains the heavenly bodies. Normally people...

Evidence for Inflation, or Inflating the Evidence? Feb 24, 2009 — Cosmic inflation has become an accepted truth in cosmology, but its appeal is primarily philosophical and theoretical. Something as weird as a universe jumping 26 orders of magnitude in size in one trillion trillion trillionth of a second (see 02/21/2005) should raise eyebrows in any scientific circle. Is there any evidence for it?...

Scientists announced today new evidence supporting the theory that the infant universe expanded from subatomic to astronomical size in a fraction of a second after its birth. The finding is based on new results from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) satellite, launched in 2001 to measure the temperature of radiant heat left over from the Big Bang, which is the theoretical beginning to the universe. This radiation is known as the Cosmic Microwave Background (CMB), and it is the oldest light in the universe. Using WMAP data, researchers announced in 2003 that they had pieced together a very detailed...

(301) 286-7745 March 16, 2006 RELEASE: 06-097 NASA Satellite Glimpses Universe's First Trillionth of a Second Scientists peering back to the oldest light in the universe have new evidence to support the concept of inflation. The concept poses the universe expanded many trillion times its size in less than a trillionth of a second at the outset of the big bang. This finding, made with NASA's Wilkinson Microwave Anisotropy Probe (WMAP), is based on three years of continuous observations of the cosmic microwave background (CMB), the...

A handful of researchers posit an alternative theory of origin — the universe has no beginning Many, if not most, people assume that certain aspects of nature’s workings are absolutely known. Outside of intelligent design circles, no modern biologist doubts the theory of evolution by natural selection; it is too well established by harmonious data across a multiplicity of fields. No credible doctor questions the germ theory of disease. And, one might think, no serious cosmologist disagrees with the standard cosmological model. The SCM is the official designation of what is informally called “the big bang”: that relatively recent but...

Creationist cosmologies explain the anomalous acceleration of Pioneer spacecraft by D. Russell Humphreys A broad class of creationist cosmologies offer an explanation for the ‘Pioneer effect’, an apparent small Sunward anomalous acceleration of the Pioneer 10 and 11 spacecraft. If a large volume of empty space surrounds the matter of the cosmos, so that the cosmos can have a centre of mass, then the matter is in a deep gravitational potential ‘well’. If space is expanding and spreading the matter outward, then the depth of the well is decreasing. According to general relativity, especially a new solution of Einstein’s equations...

WHEN he was buried - at the insistence of the Catholic Church in unconsecrated ground - Galileo Galilei left behind at least two conundrums: how could a man with impaired eyesight have made the observations that revolutionised astronomy; and did his faulty vision alter what he saw and recorded? When his body was moved to the Basilica of Santa Croce in Florence, some 100 years later on the initiative of local freemasons, it gave rise to a third riddle: who was the woman found buried alongside him? Scientists are planning now to solve all three questions with the help of...

A Brief History of Intolerance in Modern Cosmology by Dr. Jerry Bergman January 21, 2009 Abstract A review of some recent well-documented cases of intolerance in the cosmology field illustrates a common problem in science. Many relate to the Big Bang theory, such as the case of Geoffrey and Margaret Burbidge and Halton Arp. None of the accounts involved Intelligent Design advocates or creationists. This selection removes this compounding factor from the evaluation, but the cases have direct relevance to both Intelligent Design and creationism because both groups face the same resistance. It was concluded that it is critical for...

DRIVING through the countryside south of Hanover, it would be easy to miss the GEO600 experiment. From the outside, it doesn't look much: in the corner of a field stands an assortment of boxy temporary buildings, from which two long trenches emerge, at a right angle to each other, covered with corrugated iron. Underneath the metal sheets, however, lies a detector that stretches for 600 metres. For the past seven years, this German set-up has been looking for gravitational waves - ripples in space-time thrown off by super-dense astronomical objects such as neutron stars and black holes. GEO600 has not...

The UWA Zadko Telescope, owned by the University of Western Australia, was the first one in the world to capture the massive Universe event that saw a giant star collapsing into a black hole and emitting a massive gamma ray burst , fortunately for us in a very distant galaxy. The emission is believed to be about 11 billion years old, and is visible only now because of the time the light needed in order to travel from the site of the collapse to our planet. Australian astronomers say that, if such an explosion were to happen in a place...

ABHAY ASHTEKAR remembers his reaction the first time he saw the universe bounce. "I was taken aback," he says. He was watching a simulation of the universe rewind towards the big bang. Mostly the universe behaved as expected, becoming smaller and denser as the galaxies converged. But then, instead of reaching the big bang "singularity", the universe bounced and started expanding again. What on earth was happening? Ashtekar wanted to be sure of what he was seeing, so he asked his colleagues to sit on the result for six months before publishing it in 2006. And no wonder. The theory...
