experiments provide new data that is not explained by current theories, which of the following are true? Choose all that apply.     The scientists that collected the data made a mistake     The existing theory must immediately get thrown out     The existing theory should be altered to account for the new data     The experiment should be conducted by other scientists to see if the data is correct     The experiment should be repeated by the same scientists     A completely new theory might be necessary, but it must be able to explain previously verified results from the existing theory
