All these questions about Chazal’s inventions and why they did not build atom bombs for protection is such a crock. Chazal knew the source (i.e. G-d) and they knew why plagues and other hardships were sent. They knew atom bombs would be ineffective against an enemy Hashem sends because of Sinas Chinam.
These arguments of yours don’t prove that our Chachamim didn’t know science. They prove that you know neither Chachamim nor G-d.
