“Chazal knew what was known in their time , but not more.”
The Chasam Sofer (Beshalach) writes Chazal know science from the Torah.
The Aruch Hashulchan (EH 13) writes someone who disagrees with Chazal on scientific matters, testifies about himself that he does not believe in Torah she bal peh, even though he would be embarrassed to admit it outright.
There are many additional meforshim stating the same. But this is a good start.
