The most likely outcome if scientists use updated technology and make new discoveries about a theory is:
A new theory will take the place of the old one.
Scientific theories are refined or replaced as new evidence and technologies provide better explanations for observed phenomena. It is important to note that while theories can evolve with new discoveries, they generally do not become laws; the distinction between theories and laws in science remains intact. Further experiments may confirm or challenge the new discoveries, but the most direct consequence of significant new findings is often the development of a new or revised theory.
