Is Data Science a science?

At its core, all fundamental science is about making predictions in the form of experiments: precise, quantifiable, falsifiable predictions. As Richard P. Feynman put it: "The fundamental principle of science, the definition almost, is this: the sole test of the validity of any idea is experiment." So if science is about making predictions, how is it different from the predictions that astrologers make? The core distinction is in the kinds of predictions each makes. Most horoscopes, for example, will give you general predictions.
