Cosmologist Luke Barnes answers 11 objections to the fine-tuning argument

This is from the blog Common Sense Atheism. (H/T Allen Hainline)

Atheist Luke Muehlhauser interviews well-respect cosmologist Luke Barnes about the fine-tuning argument, and the naturalistic response to it.

Luke M. did a good job explaining what was in the podcast. (I wish more people who put out podcasts would do that).

Details:

In one of my funniest and most useful episodes yet, I interview astronomer Luke Barnes about the plausibility of 11 responses to the fine-tuning of the universe. Frankly, once you listen to this episode you will be better equipped to discuss fine-tuning than 90% of the people who discuss it on the internet. This episode will help clarify the thinking of anyone – including and perhaps especially professional philosophers – about the fine-tuning of the universe.

The 11 responses to fine-tuning we discuss are:

  1. “It’s just a coincidence.”
  2. “We’ve only observed one universe, and it’s got life. So as far as we know, the probability that a universe will support life is one out of one!”
  3. “However the universe was configured, evolution would have eventually found a way.”
  4. “There could be other forms of life.”
  5. “It’s impossible for life to observe a universe not fine-tuned for life.”
  6. “Maybe there are deeper laws; the universe must be this way, even though it looks like it could be other ways.”
  7. “Maybe there are bajillions of universes, and we happen to be in one of the few that supports life.”
  8. “Maybe a physics student in another universe created our universe in an attempt to design a universe that would evolve intelligent life.”
  9. “This universe with intelligent life is just as unlikely as any other universe, so what’s the big deal?”
  10. “The universe doesn’t look like it was designed for life, but rather for empty space or maybe black holes.”
  11. “Fine-tuning shows there must be an intelligent designer beyond physical reality that tuned the universe so it would produce intelligent life.”

I’m going to put the list of resources for the podcast that Luke M. mentioned in his post, but without the actual hyperlinks. It saves me having to type up a summary. If you want to click the links that I removed, go over to Common Sense Atheism and the links are there.

Links for things we discussed:

  • Fine-tuned universe
  • Cosmological constant
  • Miss Marple
  • Other forms of life and Daleks
  • Elliot Sober
  • Cosmic inflation
  • The graceful exit problem
  • Carr and Rees, “The Anthropic Cosmological Principle and the Structure of the Physical World” (1979)
  • David Lewis’ modal realism
  • Boltzmann’s multiverse
  • Roger Penrose argues that some modern multiverse theories face the same problem that Boltzmann’s multiverse faces in The Road to Reality.
  • Everett’s multiverse
  • Wheeler – At Home in the Universe
  • Thorne-Hawking-Preskill bet
  • Edward Robert Harrison
  • Luke responds to PZ Myers
  • You can find some good talks by Polkinghorne and Ellis on fine-tuning at the Faraday Institute’s multimedia page.
  • William Lane Craig, “Design and the Anthropic Fine-Tuning of the Universe“
  • Robin Collins, “The Teleological Argument“
  • Good stuff: Davies – The Goldilocks Enigma; Rees – Just Six Numbers; Barrow – The Constants of Nature; Barrow & Tipler – The Anthropic Cosmological Principle; Leslie – Universes; George Ellis articles.
  • Fred Adams and Luke’s critique
  • Luke’s critique of Hector Avalos
  • Luke’s critique of Victor Stenger: part 1 and part 2
  • Luke’s critique of Hugh Ross
  • Luke’s critique of William Lane Craig: part 1 and part 2

I thought the funniest part was the Natalie Portman part. Boy, do I wish more atheists would listen to this podcast and understand what the fine-tuning argument is actually about. Luke M. gave Luke B. a ton of time to talk. There is a very good explanation of some of the cases of fine-tuning that I talk about most on this blog – the force of gravity, the strong force, etc. as well as many other examples. Dr. Barnes is an expert, but he is also very very easy to listen to even when talking about difficult issues. Luke M. is very likeable as the interviewer.

  1. Fabulous information. I have my work cut out for me tonight. The effort you make to read & review all this material is so appreciated. This represents an incredible amount of hard work on your part. Could not be for a better eternal cause.

      1. I listened to the interview/talk. Wow, what a lot of info packed into an hour. I’ll need to go through this again. Fascinating topics indeed. I did not know much about Luke Barnes before. His book suggestions seem worthwhile and I’ll be reading some of these. Was a bit surprised to hear Barnes’ criticism of Hugh Ross.
