Why do theories of the origin of the universe change?

Theories of the origin of the universe change due to advancements in technology and observational methods, which provide new data that challenge existing paradigms. Additionally, as scientists develop more sophisticated mathematical models and interdisciplinary approaches, they may reinterpret existing evidence or discover new phenomena. The dynamic nature of scientific inquiry, where hypotheses are constantly tested and refined, also contributes to the evolution of these theories. Ultimately, the quest for a deeper understanding of the universe drives the continual reassessment and modification of its origin theories.
