A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence. It is developed through rigorous testing, observation, and experimentation. For example, the theory of evolution explains how species change over time through processes like natural selection, supported by extensive research in fields like genetics and paleontology.
Unlike a simple guess or hypothesis, a scientific theory is widely accepted by the scientific community because it has withstood repeated testing and scrutiny. Theories can evolve as new evidence emerges, making them dynamic and adaptable, much like the theory of relativity proposed by Albert Einstein, which transformed our understanding of space and time.
