A continuing bone of contention in modern physics is the strange manner in which our universe seems perfectly tuned to give rise to life. For some, it is evidence that our existence is no accident, while more skeptical thinkers have suggested that the thinking is back to front – and we only see things as perfectly tuned because life was what arose under the conditions of our universe.

The video above is from a recent discussion hosted by the Institute of Art and Ideas titled “A Goldilocks World“, featuring philosopher Massimo Pigliucci, M-Theorist and author of Universe or Multiverse? Bernard Carr, and Oxford constructor theorist Chiara Marletto:

Is the universe finely tuned for life? Copernicus and Darwin taught us to be skeptical of feeling we were special. Yet from the size of the electron to the cosmological constant our universe is strangely fine-tuned for life. Is this a spectacularly fortuitous accident? Has the universe been tailored for us or do the theories just make it look that way?
