Neil Turok: Endless Universe

[1over137]

Has someone read his book? (http://endlessuniverse.net/) Are there some problems with his theory?
I have not read his book yet, just discovered it.

Infinite regress alert... infinite regress alert...

Their theory is based on the cyclical model which results in all kinds of absurdities (such as time needing time at the rounding edge of a singularity before another bounce). I also doubt the book addresses the BVG theorem of 2003, which states that for any type of universe to be anthropic it must follow the inflationary model (having a Hubble rate of inflation greater than zero). The theorem further states that any inflationary model would have to have begun via a singularity. So it doesn't really matter how many bounces or cycles or bangs have occurred, every single one of them must have had a beginning. In other words, like Rick said, infinite regress on a cosmic scale, infinitely irrational.

Thanks Byblos : )
I've just emailed your response to authors. Am interested if they respond.

Not that I object but as a matter of courtesy you could have checked with me first.

I apologie. Sorry.

I apologie. Sorry.

No worries. Had I known though, I would have phrased it a bit differently but now you've peaked my interest, let me know if they respond.

: ) sure. you are friend Byblos. thanks.

Any time. Let's just hope what I said makes sense, considering I'm not a physicist.
