- There are laws or parameters of physics, I am told, that allow the sun to work as it does to provide us with light and heat. What attribute of physics are most important to "life" being able to exist.
The universe after the big event was a lot of lifeless stuff. However, as things settled down the rules behind the curtain were such that life was allowed to develop, they may have even been such that they encouraged the things to happen that were conducive to the process that has resulted in life. Some rule, some physics value that if it was somewhat different it is considered unlikely that life would have been likely. I am not asking what a parameter is what it is or how that parameter was established, I am interested in which parameters are most important to "life" existing. This also assumes that in a universe that is consistent from place to place that life is also likely from place to place.
