This, a lengthy and thorough read well worth the effort.
In which Lawrence Roberts summarizes - with shortfalls, the current state of Cosmology, and makes suggestions and revisions that he thinks may help us on to a greater (and improved) understanding. One of his postulates suggests that gravity accreting at the end of the visible universe may help to explain the red-shifting we have long attributed to expansion.
There are some very good ideas here, well and simply explained so that someone with almost no experience in what he's discussing can come to a comprehension of what he's suggesting.
