Extractions: Physical cosmology Related topics edit In cosmology , the cosmic microwave background radiation (CMB) is a form of electromagnetic radiation discovered in that radiates throughout the universe in the microwave range. edit The principal feature of the CMB is how closely it matches a black body spectrum . Although the temperature of the CMB varies from point to point (i.e. it contains small anisotropies), the spectrum in a particular direction almost exactly resembles a black body . The CMB radiation frequency ranges from 0.3 GHz to 630 GHz, and peaks at 160.4 GHz, corresponding to a temperature of 2.725 kelvins There are however very small yet significant variations ( anisotropies ) from the black body spectrum. The most pronounced is the dipole anisotropy (180 degree scales) which is at a level of about 10

Extractions: ANU Billboard National Institutes Staff Pages Wednesday January Australian astronomers from the Anglo-Australian Observatory, The Australian National University and the University of New South Wales, together with their UK colleagues, today announced that they have found the 'missing link' that directly relates modern galaxies like our own Milky Way to the Hot Big Bang that created our Universe 14 thousand million years ago. This is the result of a 10-year effort to map the 3D distribution in space of 220,000 galaxies using the 3.9-m Anglo-Australian Telescope (AAT) in New South Wales â a project called the 2-degree Field Galaxy Redshift Survey (2dFGRS). This survey was almost ten times larger than any previous such study. It measured in detail patterns in the distribution of galaxies, on scales from 100 million to 1 billion light-years. Subtle features in these patterns were set by physical processes that operated when the universe was very young, and reveal the 'missing link' between present-day galaxies and the Big Bang.

Extractions: The hot Big Bang model is the currently accepted description of the universe's origins. This theory hypothesizes that the universe as we know it was born in an explosion of tremendous proportions. The three main observations supporting the big bang model are the Hubble expansion, the cosmic microwave background, and the relative primordial abundances of light elements (Helium 3 and 4, Deuterium, Lithium) Following are brief explanations of these observations and how they support the notion of the grand explosion called the Big Bang. A familiar law to astronomers is that the apparent brightness of an object decreases with increasing distance (as the inverse square of the distance). The farther away an object is, the darker is it. This relation, along with more sophisticated techniques described in the second lecture " Expansion of the Universe"

Extractions: The COBE DMR maps reveal the Universe when it was roughly 300, 000 years old (past the beginning of the Big Bang and time as we understand it). This seems to be quite old by human standards until we compare it to the current age of the Universe of about 14 billion (14 x 10^9) years today. Put in human terms, if the Universe were a middle-aged person today, then the epoch revealed by the COBE DMR maps corresponds to an image of an embryo at 10 hours age. Thus we have an image of the Universe at an extremely early epoch in its development. The COBE DMR discovery had an immediate public and scientific impact. The public and media interest was overwhelming. The COBE DMR results were carried on the front page of most newspapers throughout the world. Media interviews and public discussion continued for months. Magazines carried in depth stories and a number of scientific TV shows featured the results. The implications of an image of the very early Universe were well appreciated by the media and the public. NASA was properly proud of its first satellite dedicated to cosmology.

They reveal much about the nature of the Big Bang, the density of baryonic matter, nucleosynthesis and the formation and evolution of stars and galaxies ( Figure 1 : Cosmic abundances elemental abundances of the solar system). The majority of objects in the Universe are made mainly of hydrogen and helium, which contribute by mass of respectively 70 and 28 per cent of all baryonic matter in the Universe. Hydrogen and helium (as well as the very rare lithium) were manufactured during the first three minutes of the Big Bang approximately 15 billion years ago which starts the current observable universe. The remaining 2 per cent are heavy elements (all elements except H, He are loosely called `metals' by astronomers and thus `heavy') are later synthesized by generations of stars which glow by burning hydrogen and helium at the centre. Carbon, nitrogen and oxygen are the most abundant heavy elements. Oxygen is created by supernovae (mainly massive stars), while carbon is created by low-mass stars (red giants, planetary nebulae) and nitrogen is a mixture of the above two sources (

Big Bang Model The big bang theory, or more precisely described as the big bang model, which is a model of physics and astronomy (more specifically, astrophysics). http://www.geocities.com/darrickdean/bigbangmodel.html
Extractions: The best data we have [on the big bang] is exactly what I would have predicted had I nothing to go on but the Bible as a whole. Arno Penzias, Nobel Prize winning co-discoverer of background radiation The big bang theory, or more precisely described as the big bang model, is one of the most often misunderstood theories of science, especially by certain creationists and skeptics. This is the result of not studying the model itself, replacing the science with personal beliefs and not testing what others claim. First, a definition. The big bang creation event did not sound a bang, it was a sudden expansion of space that carried matter and energy with it, beginning from what is called a singularity. A singularity has an infinitesimally small volume, whose shape may have been similar to a dimensionless point or plate (which shape is still not fully understood). A black hole is a type of point singularity we know to exist. No space, time, matter or energy existed before the big bang event. Some young-earth creationists (who believe the universe is 10,000 years old or less) try to discredit the big bang or claim it is invalid. They do so because the big bang supports an ancient universe, which contradicts their interpretation of Genesis. Because of the big bangs support of an ancient universe, these creationists claim this model supports naturalistic biological evolution. On the contrary, as we will shortly see, neither the big bang nor ancient universe supports the theories resulting from naturalism.

The basic physical processes that govern the stars and gas in galaxies will be discussed. The course will particularly focus on the physics of nearby galaxies, the properties of distant galaxies in the early universe (a billion years after the Big Bang), the formation of galaxies from an initial very homogeneous and isotropic matter distribution after the Big Bang, and on the dark matter content of galaxies and the supermassive black holes that they host. The course will be in English.
FRS: From The Big Bang To DNA The course will begin with a description of the big bang, introductory cosmology, and an understanding of how matter was created. We will discuss the immune http://trc.ucdavis.edu/trc/freshSem/sp04/gershwin.html
Extractions: Format: This will be an audience-participated seminar series in which students will present, followed by a discussion by Dr. Gershwin. The first class will be a lecture by Dr. Gershwin entitled "Astrobiology: The Way We Were and the Way We Are Today." Thereafter, students will be assigned individual topics and will meet individually with Dr. Gershwin to obtain selected reading lists. There will be no formal text but there will be required reading. The course will meet for two hours per week in the late afternoon or early evening. Students will have an additional 2-3 hours per week of reading. Grading: Students will receive a grade based on class participation (1/3). Each student will also be graded on their oral presentation (1/3). Finally, there will either be a written final essay of no longer than 3,000 words, or a class debate in which the class will be divided into two groups to "argue" in favor of or against a hypothesis (1/3).
