RJA #9: Evaluation of Sources

Looking at all of my sources, I find that some of the most useful ones include videos I found at Videosurf.com (search documentaries on the big bang theory.) I find this helpful because There are many scientists and astrophysicists talking about it who know a lot about the theory.
Umich.edu is another valuable and useful source.It is a large article written by scientists (with references of many other scientists and relavant books.)
There is a book I am looking at reading call "The Big Bang" by Paul Fleisher that has tons of good information on how they came about the theory of the big bang, and why they feel it is a reliable source of how the world began.
There is a periodical article at http://www.encyclopedia.com/topic/big-bang_theory.aspx that too has reliable sources to use for my paper.
A text in http://ssscott.tripod.com/BigBang.html is useful. There are pictures and diagrams and many sources of information supported by some respected scientists. What I have read appears to be relavant and reliable.
The other resource I found most useful is called All About Science. This article i found at http://www.big-bang-theory.com/ The sources that created this article were all non-fiction books, and documentaries on my subject. The article is not that long, but breaks the theory down by it's main points.
I have many other sources I will be looking at when writing my paper, which you can find in my blog. however, these were the sources i found to be the best.
