Final answer:
Scientific laws can be changed if new evidence contradicts them.
Step-by-step explanation:
No, your friend is not correct. A scientific law can be changed if new evidence contradicts it. Scientific laws are descriptions of patterns in nature that have been observed and verified to be true in all circumstances studied so far. However, if new evidence emerges that contradicts a well-established law, then the law must be modified or completely overthrown. Laws can never be known with absolute certainty, and the scientific community is always open to revising or discarding laws based on new evidence.
