Universe

{{Main|Fine-tuned universe}}
The fine-tuned universe hypothesis is the proposition that the conditions that allow the existence of observable [[life]] in the universe can only occur when certain universal [[physical constant|fundamental physical constants]] lie within a very narrow range of values. According to this hypothesis, if any of several fundamental constants were only slightly different, the universe would have been unlikely to be conducive to the establishment and development of [[matter]], astronomical structures, elemental diversity, or life as it is understood. Whether this is true, and whether that question is even logically meaningful to ask, are subjects of much debate.<ref name=stanford_encylopedia>{{cite web
