Why is science compared to a never-ending puzzle of discoveries?

Science is compared to a never-ending puzzle of discoveries because every new finding creates more questions and opportunities to explore. Like a puzzle, science involves collecting information, connecting ideas, and finding explanations to understand the world better.

Scientists continuously observe, investigate, and experiment to discover new facts about nature, technology, space, living organisms, and different processes. When one scientific question is answered, it often leads to new areas of research and further discoveries.

For example, learning about cells led scientists to explore genetics, DNA, and advanced medical research. Similarly, studying space continues to reveal new information about planets, stars, and the universe.

Science keeps growing because knowledge is always expanding with new evidence and improved technology. This continuous journey of questioning, learning, and discovering makes science an ongoing exploration rather than a fixed collection of facts.
