    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 it’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...

    Critics of the Bible have often said that the writings of Genesis reflect an ďunscientific viewĒ of the universeóone 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 1:6Ė8, NJKV Then God said, ďLet there be a firmament in the midst of the waters, and let it divide the waters from the waters.Ē Thus God made the firmament, and divided the waters which were under the firmament from...

(NAS), orÖ praise him in the firmament of his power. (KJV) God made the expanse (firmament) on the second day and called it ďheavensĒ (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.

    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...

    Creationist cosmologies explain the anomalous acceleration of Pioneer spacecraft by D. Russell Humphreys A broad class of creationist cosmologies offer an explanation for the ĎPioneer effectí, 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 Ďwellí. 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 Einsteinís 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...

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.

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...

Gravitationally, the Earth Ďseesí the Sun where it is this instant, not where it was more than 8 minutes ago. Newtonís famous law of gravity does not refer to time.

    The apparent absence of shadows where shadows were expected to be is raising new questions about the faint glow of microwave radiation once hailed as proof that the universe was created by a "Big Bang." In a finding sure to cause controversy, scientists at UAH found a lack of evidence of shadows from "nearby" clusters of galaxies using new, highly accurate measurements of the cosmic microwave background. A team of UAH scientists led by Dr. Richard Lieu, a professor of physics, used data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) to scan the cosmic microwave background for shadows caused by...

    The theoretical physicist Stephen Hawking is to receive the Royal Society's most prestigious prize for scientific achievement. The Copley medal is the oldest scientific award in the world and has been won by such luminaries as Charles Darwin, Benjamin Franklin, Albert Einstein and Captain James Cook. The Cambridge don, most famous for his book A Brief History of Time, will be honoured in a ceremony on November 30 for his contribution to theoretical physics and theoretical cosmology. "This is a very distinguished medal," Professor Hawking said. "It was awarded to Darwin, Einstein and [Francis] Crick. I am honoured to be...
  • At last, the real answer to life, the Universe and everything - the ELT

    That's the Extremely Large Telescope, not just the Very Large one. ACCORDING to The Hitch-Hikerís Guide to the Galaxy, it is the answer to life, the Universe and everything. Now scientists have turned to Douglas Adamsís magic number ó 42 ó to help them to answer that question for real. Not satisfied with the spectacular views afforded by the Very Large Telescope (VLT), which is kept at Paranal Observatory in Chile, astronomers plan to build a bigger version, the Extremely Large Telescope (ELT), with a mirror measuring 42m in diameter. The project, to be undertaken by the European Southern Observatory...
  • Probing Question: What happened before the Big Bang?

    The question of what happened before the Big Bang long has frustrated cosmologists, both amateur and professional. Though Einstein's theory of general relativity does an excellent job of describing the universe almost back to its beginning, near the Big Bang matter becomes so dense that relativity breaks down, says Penn State physicist Abhay Ashtekar. "Beyond that point, we need to apply quantum tools that were not available to Einstein." Now Ashtekar and two of his post-doctoral researchers, Tomasz Pawlowski and Parmpreet Singh, have done just that. Using a theory called loop quantum gravity, they have developed a mathematical model that...

    That intergalactic road trip to Triangulum is going to take a little longer than you had planned. An Ohio State University astronomer and his colleagues have determined that the Triangulum Galaxy, otherwise known as M33, is actually about 15 percent farther away from our galaxy than previously measured.This finding implies that the Hubble constant, a number that astronomers rely on to calculate a host of factors -- including the size and age of the universe -- could be significantly off the mark as well.That means that the universe could be 15 percent bigger and 15 percent older than any previous...

    Cambridge physicist Stephen Hawking and his CERN colleague Thomas Hertog have proposed a radical new approach to understanding the universe that studies it from the "top down" rather than the "bottom up" as in traditional models. The approach acknowledges that the universe did not have just one unique beginning and history but a multitude of different beginnings and histories, and that it has experienced them all. But because most of these other alternative histories disappeared very early after the Big Bang to leave behind the universe we observe today, the best way to understand the past, they say, is to...

    University of California, Berkeley, physicist Saul Perlmutter has been awarded the 2006 Shaw Prize in Astronomy for his role in discovering that the universe is expanding faster than previously thought. Perlmutter is a UC Berkeley physics professor, an astrophysicist at the Lawrence Berkeley National Laboratory and leader of the international Supernova Cosmology Project. He shares the $1 million prize with Adam Riess of NASA's Space Telescope Science Institute and Brian Schmidt of Australia's Mount Stromlo Observatory, all recognized for their leadership of two teams, the Supernova Cosmology Project and the High-z Supernova Search. In 1998, the teams reported the acceleration...

    David Thomson and Jim Bourassa of the Quantum AetherDynamics Institute (QADI) released a new theory which mathematically predicts and explains the measured values of physics with striking precision. Their Aether Physics Model includes the "Holy Grail" of physics sought by Albert Einstein; the Unified Force Theory. "Our model shows the forces are unified by a simple set of general laws explainable as the fabric of space-time itself, which is a dynamic, quantum-scale Aether," said Bourassa. In February 2002, Thomson was observing a peculiar setup of a Tesla coil and noticed what appeared to be two distinctly different manifestations of charges....

    Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity. Charles R. Keeton of Rutgers and Arlie O. Petters of Duke base their work on a recent theory called the type II Randall-Sundrum braneworld gravity model. The theory holds that the visible universe is a membrane (hence "braneworld") embedded within a larger universe, much like a strand of filmy seaweed floating in the ocean. The "braneworld universe" has five dimensions -- four spatial dimensions plus time -- compared...

    Scientists use quantum gravity to describe the universe before the Big Bang.Scientists may finally have an answer to a "big" question: If the Big Bang was the beginning of the universe, what could have caused it to happen? Using a theory called "loop quantum gravity," a group led by Penn State professor Abhay Ashtekar has shown that just before the Big Bang occurred, another universe very similar to ours may have been contracting. According to the group's findings, this previous universe eventually became so dense that a normally negligible repulsive component of the gravitational force overpowered the attractive component, causing...
