drey kop: I have read his website and he does take issue with those who maintain that chazal cannot be wrong under any circumstances but I have not seen him mock anyone.
However, to me, the whole debate is topsy-turvy. Whether chazal knew more in scientific terms than their contemporaries is irrelevant. For the life of me, I don’t understand why chazal must know every scientific fact. What does this have to do with their holiness, their erudition and,of course, their authority in halachic matters? Just because they may not have known about the solar system does not invalidate their absolute authority in halachic matters. To assert that they knew everything, you have to go to some contorted extrapolation of their many sayings- just see what Zben levi had to concoct to make this shittah beleievable! There are plenty of rishonim who maintain otherwise. You can choose which path to follow but it surely behooves everyone to follow his own path.
