What If The Sages Are Wrong About Scientific Facts?

Dr. Marc B. Shapiro writes: Neusatz is also explicit that very few aggadot are actually the result of the Sages’ ruah ha-kodesh (p. 32a). He states that Maimonides’ astronomical views in the Mishneh Torah do not come from a holy source, but from the Greeks, and in our day must be rejected (p. 38a). He also acknowledges that at times the Sages’ opinions were based on the best scientific knowledge of their time, which we now know is mistaken (pp. 36a-36b, 38a-38b).
