  • Outer Limits Not Lively (cosmic evos confirm galactic habital zone, but are not denied tenure)

    Outer Limits Not Lively Sept 29, 2009 — One of the “cosmic coincidences” cited in the intelligent-design treatise The Privileged Planet1 is the “galactic habitable zone” – a fairly narrow region of the galaxy where planets can form and exist safely.  The outer regions of the galaxy were described as lacking the heavy elements necessary for planet formation. Score one for the authors.  New Scientist reported on a planet search by astronomers at the University of Tokyo who failed to find planets in the outer reaches of the galaxy.  “Astronomers have long doubted that life could exist there,” the article...

    Scientists have peered further back in time than ever before using instruments designed to search for a phenomenon predicted by Albert Einstein almost a century ago but not yet proven to exist. An American observatory hunting for ripples in space and time called gravitational waves has produced its most significant results yet, despite not having directly detected any. Tycho's Supernova The “non-discovery” offers insights into the state of the Universe just 60 seconds into its existence. Previous research has been unable to look back in time further than about 380,000 years after the big bang. The new window on the...
  • Study Plunges Standard Theory Of Cosmology Into Crisis

    Science Daily ^ | 5/5/2009
    As modern cosmologists rely more and more on the ominous “dark matter” to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. Even if it does exist, dark matter would be unable to reconcile all the current discrepancies between actual measurements and predictions based on theoretical models. Hence the number of physicists questioning the existence of dark matter has been increasing for some time now. Competing theories of gravitation have already been developed which are independent of this...

    String theory “philosophy” challenged --snip-- The big bang is fundamental to cosmic evolution or the idea that somehow the universe made itself. The article majored on the varying ideas that emanate from big bang philosophy, such as dark energy and dark matter etc. that are used to solve some of the “science” problems of the big bang. It then went on to say that string theory is just another one of these ideas with no basis in experimental science...

Cahill School of Chemistry, Physics and Earth Sciences, Flinders University, Adelaide 5001, Australia E-mail: Reg.Cahill@flinders.edu.au The anisotropy of the speed of light at 1 part in 10^3 has been detected by Michelson and Morley (1887), Miller (1925/26), Illingworth (1927), Joos (1930), Jaseja et al.

    Building Planets: Can’t Make Them, But HurryMay 21, 2009 — Constructing planets is a delicate business.  Trying to get tiny bits of dust to join up into balls has never been found to work.  It has to work fast, though, because unless the whole planet clears its dust lane, it will be dragged into the star in short order.  It seems you can’t get there from the bottom up, and even if you could, you’d be in trouble.  These and other problems with planet-building were discussed this month in two papers in the Annual Review of Earth and Planetary...

    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...

    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...

    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...
