Rav Yaakov’s son said that rav yaakov concluded based on that phenomenon that the given section of the rambam as based on the scientists of that time who apparently had a mistake.
He concluded that that part of the rambam was not torah.
However, something equaly troubling to some in today’s environment, the rambam wrote things which were science(and not torah) in his great book.
The speech he(Rav Noson) gave is available online(goggle “making of a ban” and “yu”)
