Is the universe fine-tuned for life and is this evidence for God?

Sometimes people ask about fine-tuning and I created this overview to just provide links to all of my fine-tuning blogs on CrossExamined.org. I’ll update this as I add to this. I defend this fine-tuning claim which is actually widely accepted in the physics community:

“In the set of possible physical laws, parameters and initial conditions, the subset that permits rational conscious life is very small.”

Of course whether that implies design is more controversial but I defend the case that it does:

Intro/Philosophical Background

If You Don’t Want God, You Better Have a Multiverse!

How Does Fine-Tuning Provide Evidence for God?


Evidence

Fine-Tuning of Initial Conditions to Support Life

Many Changes to the Laws of Physics Would be Life-Prohibiting

Fine-Tuning of the Force Strengths to Permit Life

Fine-Tuning of Particles to Support Life


Objections

Mistaken Objections that Seek to Trivialize Fine-Tuning

Important Objections in the Fine-Tuning Debate

But We Can’t Even Define Life

Coarse-Tuning vs. Fine-Tuning

For a more in-depth defense of the scientific case (and some excellent philosophical points), I highly recommend Cosmologist Luke Barnes:

  • Dr. Barnes has an excellent podcast for popular audiences.
  • Here is the most comprehensive peer-reviewed review article on Fine-Tuning and an excellent rebuttal to Fine-Tuning skeptic Vic Stenger.
  • Barnes has some excellent videos on this topic as well – here is one.
  • Finally here are some excellent blogs by Barnes on this topic.
