Basic Fundamentals of Cosmology

  1. Dec 5, 2007 #1
    To begin with, I'll let you know I am a student. I am prone to theoretical physics and philosophy over cold, hard, mathematical fact. That being said, I was recently intrigued by a few things I learned regarding the Big Bang Theory.

    I'm still really shaky on the topic, though, and I could use a few good resources if anyone has information, sites, or books that I should look up. While I know the basic principles of the Big Bang, I'm confused over the recent controversy regarding red-shift and quasars. I also have no idea what an FLRW and FRW model is. I'd be glad to learn about anything else someboyd on the forums thinks is in any way important or pertinent.

    I am very much aware that there is a lot to cover, but is there anyhing that can help me both deepen my understanding of the theory and understand the talking points of the nay-sayers and those fueling the controversies? I'm looking for any information that can educate and/or enlighten me. Thanks to anyone who helps me out.

    High school? University

    Do you mean this? Or soemthing else?

    FLRW stands for Friedman-Lemaitre-Robertson-Walker model of the universe. Sometimes poeple leave out Lemaitre, but after recently reading more about him, I'll try not to do this. It is a solution of Einstein's equation of general relativity that models a homogeneous, isotropic, expanding universe.

    At what level?

    Books are the best source of information. Barbara Ryden's Introduction to cosmology is particularly readable (for those that have a second-year physics background).

    Ned Wright has a fantastic cosmology website.

    Well, I'm currently a senior in high school enrolled in AP Physics. However, I'm taking courses through LIU and Seton Hall as well. I just figured I might as well let everyone know I'm not the most well-versed in physics compared to many of the others on the site, I'm just learning. But please don't hold back information that requires a greater ability to comprehend. I don't believe I am the high school level.

    About the thread you left me, it is actually the kind of stuff I was talking about. I recently came into contact with some of Halton Arp's admirers' sites. They are very ambiguous at best and I was looking for support for what they claim, or any information that refutes his work. Either way, anything that helps me be a little more learned about red-shift and quasars in general is appreciated.

    But any information you have at all, up to any level, I'll take. I have a fantastic ability to retain what I'm taught or shown and I'm looking to become very well-versed in BBT.

    I'm willing to read and learn anything you have to offer.
