Fine-tuning in Cosmology

I forgot to post a link to a paper by Fred Adams that appeared on the arXiv last month on the topic of the fine-tuning of the Universe which I had bookmarked for a blog a while ago.

My heart always sinks when the arXiv informs me that the abstract of a paper is `abridged’ so here’s the full version from the PDF you can download for yourself here. Please be aware, though, that it’s a lengthy paper running to over two hundred pages:

My own view on this topic is that it is indeed remarkable that the Universe is finely-tuned to exactly the extent required to allow authors to write such long papers about the fine-tuning of the Universe…

One Response to “Fine-tuning in Cosmology”

  1. Wow! 212 pages! Note the reference:

    [345] G. F. Lewis and L. A. Barnes, A Fortunate Universe, Cambridge Univ. Press (2016)

    I reviewed that book a while back. Essential reading, even if you don’t agree with everything. And you won’t, since the two authors don’t agree on everything. I think that this is a very important point: the existence of fine-tuning is independent of the mechanism used to explain it. Some people avoid the topic, or deny that fine-tuning exists, because they don’t like any of the mechanisms.
