Extractions: Dr Michael Hobson reveals how Crimewatch led his research in a new direction "Have you ever wondered how astronomers produce those wonderful pictures that appear in the papers or on television from time to time? They certainly look very impressive, but in many cases it has taken a lot of work to turn the signal received by the telescope into a clear image of a star cluster or distant galaxy. The basic images produced by telescopes often bear only a passing resemblance to the final pictures presented in the media or scientific journals. These `raw data' (as they are called) usually suffer from `blurring' and `noise' caused by the inevitable imperfections inherent in any measurement process. Therefore, an important part of modern astronomy is to develop ways of processing the raw data to remove these unwanted artefacts, and produce a clear picture, worthy of a slot on the Ten O'Clock News As an astronomer working in the Cavendish Astrophysics Group in Cambridge for the last 10 years, I have been very closely involved in developing a wide variety of `image reconstruction' techniques. These are basically mathematical algorithms that run on a (usually very large) computer. The program reads in the blurred, noisy data and attempts to reconstruct the actual image the telescope observed (which we generally call `the truth').
Fred Hoyle And The Mythical Big Bang - Jean Claude Pecker was indeed a splendid solution, and he said it in more or less that way the BigBang is nothing We were all beginners in astrophysics; Fred was the older. http://www.humanist.org.nz/Docs/BigBang.html
Extractions: Fred Hoyle and the origins of the Universe. S ir Fred Hoyle died at the age of 86, on Monday August the 20 th , at Bournemouth, UK, where he had retired several years ago. He was, no doubt, still the young man he has ever been, active, creative, unconventional, multi-talented, interested by everything, deeply sensitive, exceptionally imaginative, and strongly uncompromising. Jean Claude Pecker Born on June 24 th , 1915, he displayed very early an obvious taste for the "mysteries" of the Universe, for its beauties, and for astronomy. At the age of 13, he is said to have observed the sky every possible night,with a small telescope. Later, after his Doctorate Thesis on Quantum Electrodynamics, defended at Cambridge in 1939, as a student of Allen Smailes and Paul Diracand later, disgusted by the military applications of nuclear physics, he turned towards astrophysics, then influenced by his friend Raymond Lyttleton. He became Plumian Professor of Astronomy And Experimental Philosophy at Cambridge in 1958, until 1972. He kept very close relations with foreign universities and observatories. He worked at the Mount Wilson and Palomar Observatories (although he was essentially a theoretician), at Cal-Tech, and also at Cornell University where he was professor at large from 1972 until 1978, and kept very close working relations with astronomers all over the world, Fritz Zwicky, Halton Christian (Chip) Arp, William (Willi) Fowler, Geoffrey and Margaret Burbidge, in the USA, N. Chandra Wickramasinghe, Jayant V. Narlikar, in India, and in the UK, not to speak of his earlier Cambridge accomplices, Thomas Gold, Sir Hermann Bondi, and of course Lyttleton.

We are all so accustomed to reading that the universe "began" once a time in the Big Bang that most people no longer think it necessary to question or scrutinize it. A detailed analysis of the Big Bang theory, however, leads to consequences and implications that are irrational, or are contradicted by astrophysical observations, including important ones.

Extractions: ONLINE No. 54: Nov-Dec 1987 Issue Contents Sourcebook Project Sourcebook Subjects Doubts concerning the validity of the Big-Bang hypothesis must be becoming more serious, when the conservative Scientific American devotes an entire page to dissenters and their data. After all, the Big Bang, like Evolution and Relativity, is a vital part of the general scientific outlook. How shaky is the Big Bang? L.M. Krauss of Yale, admits that all cosmological theories are "tenuous." He adds: "There are a lot of fundamental assumptions we base our model on that may be wrong." A leading Big-Bang basher in H. Arp, of whom we have written frequently in SF. We will therefore not pursue his sort of bashing any further here. It is sufficient to say that Arp's doubts about the red-shift/distance relationship continue to receive support through observations of the heavens and in the lab. The other Big-Bang basher featured in Scientific American is H. Alfven, a Nobel-Prize winner in physics. Alfven postulates a universe dominated by electromagnetic forces, which he believes to be more important in shaping the cosmos than gravitation. His electromagnetic theory disallows any universe smaller than 1/10 the diameter of our present universe, thus excluding the Big Bang's point origin. Electromagnetic forces can account for all types of galaxies without resorting to the infamous "missing mass." Alfven can even account for the cosmic microwave background. Furthermore, Alfven's theories are supported by observations of solar-system plasma and magnetic fields. NASA's T.E. Eastman allows:

With this purpose, theoretical astrophysicists create and evaluate models to reproduce and predict the observations. In most cases, trying to figure out the implications of physical models is not easy and takes a lot of time and effort. Theoretical astrophysicists use a wide variety of tools which include analytical models (for example, polytropes A polytrope is a solution to the Lane-Emden equation.

Stars appear as points in the nighttime sky that twinkle because of the effect of the Earth's atmosphere. The Sun is an exception: it is the only star sufficiently close to Earth to appear as a disc and to provide daylight. Common language does not always reflect this astronomical usage; the term "star" ordinarily does not include the Sun, and sometimes includes the visible planets and even meteors ("shooting stars" or "falling stars").

Extractions: The Big Bang theory, in its modern embodiment as popularly taught in the schools, is offered as a refutation of Divine Creation. The universe is said to have happened by accident without a need for God. Starting from the chaos of an explosion, matter became spread out across the universe yet able to gather together into stars and galaxies all under the influence of purely natural laws. (Actually, there are multiple scientific theories offering different details for how the Big Bang occurred, but at the popular level, we still speak of "the Big Bang theory.") Of course, the Big Bang theory cannot explain the origin of those natural laws and the many particular constants such as the strength of gravity or the mass of the electron, all of which seem so precisely tuned to permit stars and planets and life to exist. But the modern atheistic does injustice to history: the Big Bang theory was initially viewed as a major blow to atheists and as crucial evidence for God. "Let there be light" - the divine command that began the Creation, bringing order out of chaos - was viewed as fulfilled by the Big Bang. A carefully orchestrated explosion that could lead to life in the universe surely must have had a cause, and that cause was God.

Extractions: Astronomers using the giant 10 meter Keck telescope have made the most precise measurement to date of the amount of deuterium, or heavy hydrogen, in the universe. This finding provides a stringent constraint on the Big Bang theory for the origin of the universe. Led by David Tytler of the University of California, San Diego, a team of six astronomers observed absorption lines in light from a quasar. Specific wavelengths of the quasar light were absorbed by various types of atoms in an intervening, and very distant intergalactic cloud. They determined that the cloud contained about one deuterium atom for every 40,000 normal hydrogen atoms. This number, which is consistent with other independent measurements, gives the team confidence that they and other scientists are closing in on one of the most important pieces of evidence for proving the Big Bang theory. "According to the theory, primordial deuterium was created by nuclear reactions in the first one thousand seconds of the Big Bang," explained Tytler. "The amount depends sensitively on the number of protons and neutrons present, so if we measure the deuterium, we can determine how many protons, and therefore how much matter is present in the universe."

Extractions: The objective of this research program is to investigate nuclear processes that take place in stars, in the big bang, and in interstellar and intergalactic space. Nuclear phenomena are ubiquitous in the universe. The stars shine by nuclear energy, and the chemical compositions observed in the solar system and elsewhere are the results of nuclear processes that occurred in the big bang and inside the several generations of stars that have formed since then. Many astrophysical phenomena may only be understood by a combination of nuclear physics with methods more familiar to astrophysicists. A particularly important problem is to determine rates for the nuclear reactions that occur in astrophysical environments. We have applied advances in the theoretical descriptions of light nuclei to compute cross sections important for big-bang nucleosynthesis and the solar neutrino flux. This work continues in close connection with our other work on light nuclei, and the main goals at present are to improve the wave functions and computational methods. There are many applications (for example, the rapid neutron capture process) where large contributions from theoretical nuclear physics particularly masses and cross sections will always be necessary as input, and we maintain research interests in these areas. Understanding nucleosynthesis and energy generation in a particular astrophysical environment requires calculations of nuclear reaction networks. Even for cases in which the detailed astrophysical phenomena can only be understood from difficult calculations coupling a reaction network and hydrodynamics, simpler network calculations can identify the crucial reactions and other nuclear properties to be determined by more detailed theoretical and experimental work. Ongoing work in this area involves big-bang nucleosynthesis, nuclear burning in low-mass stars, and photon-nucleus reactions in high-energy cosmic rays.

PRIMORDIAL MAP. The intensity and polarization of the cosmic-microwave-background radiation recorded by the Degree Angular Scale Interferometer. Among the tiny variations in temperature, yellow is hottest and red is coldest. Each black line's length represents strength of polarization at a location; its orientation reflects direction. DASI Collaboration Revealing for the first time that microwave-background photons from adjacent patches of the sky vibrate in slightly different directions, the discovery confirms that by studying that background "we really are observing the universe as it was about 300,000 years after the Big Bang," says theorist Wayne Hu of the University of Chicago. The finding verifies that just about everything astronomers thought they understood about the early universe and the emergence of galaxies is likely to be true, he adds. Had astronomers not detected the polarization, "we would have had to go back to the drawing board" regarding our theories about the universe, says John E. Carlstrom of the University of Chicago. He led the new study of the cosmic microwave background and announced the results last week at the Cosmo-02 meeting in Chicago.
