A Goldilocks World: Introduction (01:29)
Tara Shears introduces debate participants Chiara Marletto, Bernard Carr, and Massimo Pigliucci. Shears introduces the first question—why does the universe appear finely tuned for life?
The Pitch: Chiara Marletto (02:49)
Marletto states that the universe is finely tuned for life in two senses—bio-friendliness and the laws of physics. The laws of physics have certain traits with three properties. Marletto argues that new tools must be developed to improve the multi-universe theory.
The Pitch: Bernard Carr (04:43)
The weak anthropic principle says given the constants of nature, there are selective places and times that we have to exist; our existence as observers imposes a selection effect on how we observe the universe. Carr proposes that the universe may appear finely tuned depending on the number and intricacies of fine-tunings.
The Pitch: Massimo Pigliucci (05:23)
Pigliucci proposes moving away from the anthropic principle and questions how much of fine-tuning is scientific.
Could the Laws of Nature Have Been Different? (13:14)
Marletto, Carr, and Pigliucci discuss whether or not the universe is finely tuned and if the laws of physics could have been different.
Does the Multiverse Solve the Puzzle? (12:35)
Marletto, Carr, and Pigliucci discuss whether or not the multiverse theory solves the problem of apparent fine-tuning.
Can we Find Answers and, if so, Where Should We Look? (06:38)
Marletto, Carr, and Pigliucci discuss whether or not an answer exists to the question of why the universes appear finely tuned for life.
