Detailed explanation-1: -A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn’t, the theory is refined or rejected.

Detailed explanation-2: -In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it’s a principle formed as an attempt to explain things that have already been substantiated by data.

Detailed explanation-3: -Theory is constructed of a set of sentences that are entirely true statements about the subject under consideration. However, the truth of any one of these statements is always relative to the whole theory.

Detailed explanation-4: -A theory is a formal explanation of the relationship among a set of observations. The observations provide evidence for the theory. Pieces of evidence support a theory in the way that legs support a table or columns support the roof of a building. Scientists develop theories to explain natural phenomena.

Detailed explanation-5: -Theories require extensive testing and agreement within the scientific community. Theories are not described as true or right, but as the best-supported explanation of the world based on evidence.
