Question: Expansion of the universe

  1. Apr 30, 2014 #1
    Hello, I started this account to ask you about that, if the place of big bang was in the middle and we are on its right side, we can't observe that what was on the left side?
    My train of thought: << (Left side, object) <<<(Big Bang)>>> (Right side, we) >>

    There was no "middle" to the big bang, no center, no left side, no right side.

    I recommend the link in my signature.

    Phind's Excellent Balloon analogy will fill in a lot of gaps, for further reading I ercommend the following, and yes the links are under my signature as well. This question is so common its handy to have on hand.

    You will find various literature to study and get started in Cosmology under my signature at,

    particular articles of interest are,

    http://cosmology101.wikidot.com/redshift-and-expansion, (note I have a few minor metric corrections to make on this one, but overall still accurate)

    some excellent articles with visual graphs etc. Will definitely clear up some misconceptions.

    http://arxiv.org/abs/1304.4446 :"What we have leaned from Observational Cosmology." -A handy write up on observational cosmology in accordance with the LambdaCDM model. ( FAQ style catch up )
    http://arxiv.org/abs/astro-ph/0310808 :"Expanding Confusion: common misconceptions of cosmological horizons and the superluminal expansion of the Universe" Lineweaver and Davies
    http://www.mso.anu.edu.au/~charley/papers/LineweaverDavisSciAm.pdf: [Broken] "Misconceptions about the Big bang" also Lineweaver and Davies

    if your interested this is a very basic article on relativity its more a historical reference article.

    http://www.gutenberg.org/files/30155/30155-pdf.pdf: "Relativity: The Special and General Theory" by Albert Einstein

    As far as historical references I've compiled numerous articles. Including

    http://arxiv.org/abs/1302.1498 " “The Waters I am Entering No One yet Has Crossed”: Alexander Friedman and the Origins of Modern Cosmology" written by Ari Belenkiy

    Reprint of one of Hubbles papers

    The "Great debate of the 20's" jubilee reprint article avalable

    The historical articles will help show how much as changed in the last century. Feel free to ask any questions and enjoy
