Brian Greene: Why is our universe fine-tuned for life?

submitted by smiley

1 decade 2 years 1 week ago

At the heart of modern cosmology is a mystery: Why does our universe appear so exquisitely tuned to create the conditions necessary for life? In this tour de force tour of some of science's biggest new discoveries, Brian Greene shows how the mind-boggling idea of a multiverse may hold the answer to the riddle.

Brian Greene is perhaps the best-known proponent of superstring theory, the idea that minuscule strands of energy vibrating in a higher dimensional space-time create every particle and force in the universe.

This type of phrasing ("fine tuned") is so confusing to laymen, weak atheists, and religious people. People like my mom hear the title and assume there must be a "fine tuner" at work.

The universe came first and then we evolved within it. Since life as we know it evolved in this universe, this universe is by definition most hospitable to life as we know it.

Yup, it's like what Douglas Adams said about the puddle of water in the pothole. "This is an interesting world I find myself in – an interesting hole I find myself in – fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!"
