PHYSICS 24 LECTURE NOTES
Topic: The Big Bang Model
January 23, 1997
LECTURER: Professor Bernard Sadoulet
STUDENT WEB PAGE AUTHORS: Dean Chen and Chris Mayor
SUMMARY
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.
1) The Hubble Expansion:
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"

Implications of the COBE DMR Map
of the Early Universe
What COBE DMR saw:
The COBE DMR ( Co smic B ackground E xplorer D ifferential M icrowave R
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.
What this meant!
Public and Media Interest
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.
This interest, support and pride made it possible for next generation experiments to obtain public, institutional, and to some extent scientific support - though the science implications and future potential would eventually provide the continuing scientific support.

    The Really
    Big Bang
    BY LIZ NEWALL
    As a child, Dieter Hartmann was fascinated with explosions. At age seven or eight, the Clemson astrophysicist recalls taking powder out of fireworks and putting them in larger containers, and, as he says, "getting a much different reaction."One of his experiments almost blew up the family barbershop in Braunschweig, Germany. "My mother was very supportive of my interests," he says. "She had even let me set up a laboratory of sorts in the basement of our shop where I did have a few accidents." All of those exploding interests became focused on outer space in 1969 when man first walked on the moon. "I remember watching it on TV and collecting every bit of printed material I could find about it," says Hartmann. His interests turned to space rockets, then to outer space itself and eventually to the most powerful explosions in the entire universe gamma-ray bursts. And ultimately his interests have helped launch Clemson into the international astrophysics spotlight through team efforts, collaborations and sheer passion for knowledge. Clemson physics students, particularly astrophysics majors, have benefited tremendously, too, by being among the handful prepared for outstanding job opportunities in the field. And not only graduate and post-graduate students benefit.

    New Reaction Rates
    For Big Bang Nucleosynthesis
    An evaluation of the 12 reaction rates most important for understanding the synthesis of elements in the Big Bang was made and published in M.S. Smith, L.H. Kawano, and R.A. Malaney, Astrophysical Journal Supplement Series 85 (1993) 219. The uncertainties of these reaction rates were also determined as functions of temperature. These are updates of rates previously given in the Caughlan and Fowler 1988 rate compilation. The valid temperature ranges of these new reaction rates are indicated with the rate, and vary from to . We reproduce analytic expressions for these rates below, in FORTRAN formats similar to that in the Caughlan and Fowler 1988 compilation.

    There are a number of existing evaluations of nuclear data important for astrophysical models. A comprehensive collection of available nuclear astrophysics datasets can be browsed at www.nucastrodata.org One dataset, the REACLIB reaction rate library, contains over 60,000 thermonuclear reaction rates. An online viewer RatePlotter for these reaction rates is also available. online in the format as they appeared in print: a text file of reaction rates as analytic functions of temperature , and tables of rates values versus temperature for each reaction. Additionally, we have extended the utility of this compilation by creating a graphical interface to select rates using the table of isotopes, and by posting GIF and Postscript plots of each rate, a downloadable fortran subroutine of all the reaction rate formulae analytic expressions for temperature derivatives of these rates, and a downloadable fortran subroutine of the reaction rate derivatives A number of reaction rates have been updated since the publication of the Caughlan and Fowler 1988 compilation. Most notably, the NACRE Collaboration revised the evaluations of approximately half of the rate collection. Additionally, we have posted a 1997 evaluation of the

    The Big Bang
    Q: Can you give a succinct explanation of the Big Bang Theory? Specifically, how is it possible that all of the atoms of all of the matter in the Universe were squeezed together into a tiny point, which then exploded? A: That's one good question. Before we get into an answer, though, let's clear up a common misconception. The Universe did not start from a single point. "The Big Bang was an explosion of space (with matter carried along), not stuff exploding from a point into space," says Dr. Michael S. Turner, Chair of the Department of Astrophysics at the University of Chicago in recent email. According to Einstein's general relativity theory, the Big Bang event was the creation of matter, energy, space, and time. So, Einstein's theory says there is no such thing as "before" the Big Bang. The Big Bang created space and time itself. You ask, how could all the matter in the Universe be squeezed together into such a patch and then explode? Your question addresses the instant of the Big Bang: Time Zero. Our present theory doesn't cover that early a time: only right after the Big Bang instant.

    by David N Schramm (Univ. Chicago)
    This volume of important papers by one the world's leading astrophysicists provides a sweeping survey of the incisive and exciting applications of nuclear and particle physics to a wide range of problems in astrophysics and cosmology. The prime focus of the book is on Big Bang cosmology and the role of primordial nucleosynthesis in establishing the modern consensus on the Big Bang. This leads into the connection of cosmology to particle physics and the constraints put on various elementary particles by astrophysical arguments. Big Bang Nucleosynthesis has also led to the argument for nonbaryonic dark matter and is thus related to the major problem in physical cosmology today, namely, structure formation. The nuclear-particle interface with astrophysics also extends to the other topics of major interest such as the age of the universe, cosmic rays, supernovae, and solar neutrinos, each of which will be discussed in some detail. Each section contains historical papers, current papers, and frequently a popular article on the subject which provides an overview of the topic. This volume is testimony to the success of the integration of nuclear and particle physics with astrophysics and cosmology, and to the ingenuity of the work in this area which has earned the author numerous prestigious awards. The book, which is accessible to beginning graduate students, should be of particular interest to researchers and students in astronomy, astrophysics, cosmology and gravitation, and also in high energy and nuclear physics.

    Isaak Luria and the Tikkun of Creation
    Yakov Leib haKohain
    In his attempt to bring about the final Apocalypse, and the coming of the Messiah, Isaac Luria turned to an analysis of the laws of the physical universe and its Creator as encrypted in the Bible, Zohar and Jewish works of Written and Oral Scripture. Armed only with these tools of Kabbalah , he developed a cosmogony which is so strikingly similar to the findings of 20th century astrophysics that one can only conclude that they were all observing the same phenomena, but from different perspectives, and the conclusions of the latter validated those of the former 400 years later. For the first time in history, Luria proposed that the Universe was created not by an orderly process, but out of a cataclysmic accident, what he called the " Shattering of the Vessels ," by which he meant the breaking of the original Ten Sefiroth resulting from a cosmic destabization in the very fabric of God Himself. Fragments (which he called Holy Sparks, or " Nitzozot ") from these Vessels of Pure Light scattered in all directions and fell into the dark realm of forms where they entered and created all "things" including man. These Sparks and the Vessels of which they are the fragments, are created by
