Sorry to pop up, but i wanted to make a suggestion for a book. It is called "The time ships" by Stephen Baxter, a very interesting story with multiple time parodoxes and a person that travels even in the moment of the big bang. It is supposed to be the sequel to H. G. Well's "time machine"...
Correct me if I am wrong. I've checked the website and I read the "flaws" as it claims of the original BB model. Doesn't most of them explained with the iflation model?
ofcourse but the eye cannot see so far as to reject a no-boundary model and from a point of view this model sounds reasonable, but then... people always have a drift of using familiar models (from everyday life) to explain something unknown.
