What happens when several experiments with new information or new technology produce results that challenge an existing theory?

When repeated experiments produce reliable results that conflict with an existing theory, scientists reconsider the theory and revise or update it to account for the new evidence. The results do not automatically prove the theory or turn it into a law, and valid evidence is not simply discarded. The correct choice is “The theory is revised or updated.”
