1. Are there important aspects of the Universe that can only be understood using the Anthropic Principle? Or is this principle unnecessary, or perhaps inherently unscientific?
Very roughly speaking, the Anthropic Principle says that our universe must be approximately the way it is for intelligent life to exist, so that the mere fact we are asking certain questions constrains their answers. This might "explain" the values of fundamental constants of nature, and perhaps other aspects of the laws of physics as well. Or, it might not.
