theories

Theories are well-supported ideas or explanations about how things work in the world. They are based on evidence gathered through observation, experiments, or analysis, and help us understand complex phenomena. For example, the theory of gravity explains why objects fall to the ground, while the theory of evolution describes how species change over time. Theories are tested and refined over time, forming the foundation of scientific understanding. They are not guesses but comprehensive frameworks that organize facts and observations, allowing scientists to make predictions and deepen knowledge about natural laws and processes.
