If a new theory better fits the data overall or simply because new and significant data disagrees or the method which brought about the original theory is invalid.
Because technology might change in the future.
Theories are ideas, educatied ideas, but still only ideas. A scientist may change a scientific theory if new facts or information are found, if other scientists' review find errors, if attempts to apply the theory are unsuccessful, or if they see that the calculations are wrong when they double check them, and so then they would retest and rewrite their theory to correct the errors.Science is testing a belief with the means to disprove it and being unable to do so.Scientific Fact = something that has yet to be disproved.

Wegner's theory was not accept because he didn't have much evidence to support his theory with and scientists thought that there might have been a land bridge between the continents. Another reason to why his theory was rejected was that he was a foreigner, by that; the scientists didn't really take him seriously.

Continuing research can turn up new or conflicting information regarding a theory or scientific law. It will then be changed even after general acceptance.

Scientific information constantly changes as new information is discovered or as previous hypotheses are retested. New information can lead to changes in scientific theories. When new facts are revealed, a current scientific theory might be revised to include the new facts, or it might be disproved and rejected.
