TED: Brian Greene: Why is our universe fine-tuned for life?
I love the TED talks: informative, thought provoking, head scratching. And I like stuff about space: photos, travel thru, possibilities of what is and what might be.
In this one, Brian Greene talks about the multi-verse and its implications. It’s about 20 min long so, if you watch it, make sure you have a few minutes to spare. Definitely a good one.
