How can the term theory be used in science and in everyday language?

In science, the term "theory" refers to a well-substantiated explanation of an aspect of the natural world, supported by a body of evidence and widely accepted by the scientific community, such as the theory of evolution. In everyday language, however, "theory" often implies a guess or a hypothesis, suggesting uncertainty rather than a robust framework. This difference can lead to misunderstandings about the strength and reliability of scientific theories compared to casual uses of the term.
