Why does the universe exist?

Abstract

The existence and specific character of the Universe pose fundamental questions that resist dismissal as meaningless or idle. The apparent fine-tuning of physical constants necessary for life suggests that the Universe’s current state requires explanation beyond mere coincidence. One possible account involves a theistic creator, though this shifts the inquiry to the existence of God and requires a resolution to the problem of evil to explain why a specific, flawed universe was chosen. Alternatively, a “many worlds” hypothesis suggests that all possible universes are actual. This framework removes the need to explain the specificity of our Universe, as all possibilities are realized, though it leaves the foundational question of why anything exists at all only partially addressed. Philosophical explanations may also appeal to logical necessity or axiological principles, suggesting the Universe exists because it is good or “ought to” be. While such views mitigate the arbitrary nature of existence, they must account for observed imperfections and the lack of a causal mechanism. If no connection between goodness and reality exists, the Universe may remain fundamentally inexplicable, necessitating a reevaluation of morality and individual purpose within a potentially neutral reality. – AI-generated abstract.
