Final answer:
The correspondence principle dictates that a valid new theory must agree with the verified results of the existing theory, ensuring accuracy and coherence with established truths.
Step-by-step explanation:
The correspondence principle states that if a new theory is valid, it must account for the verified results of the older or existing theory. Validity in this context means the accuracy of a given result in measuring what it is designed to measure. Furthermore, the correspondence principle is rooted in the idea that the truth of a new theory is judged by how well it aligns with established facts and how consistently it integrates with the body of existing truths that have been verified through observation and measurement. This reflects the necessity of coherence in scientific theories, which must both correspond to fact and cohere with other established truths in order to be accepted.
