Explanation:

Scientists use such models because the universe is extremely vast, complex, and often involves processes that occur over unimaginably long time scales or at scales too large to directly observe or experiment on. Models like the star life cycle diagram or Big Bang model simplify these complex systems and processes, making it easier to understand, analyze, and communicate the key concepts and relationships involved in the universe's structure and evolution. For example, the star life cycle model condenses the multi - stage, long - duration process of a star's birth, evolution, and death into a visual and conceptual framework that can be studied and discussed.

Answer:

Scientists use models like the star life cycle diagram or Big Bang model to simplify complex cosmic systems and processes. The universe is vast and its processes (like star evolution or cosmic origin) are hard to directly observe/study, so models make these concepts understandable and analyzable.
