I had a series of seemingly true statements that lead me to a contradiction I'm unable to solve:
- Moses knew all the Torah => Moses knew all the Halacha.
- Moses knew all the Halochos of Shabbos => when Shabbos starts and ends => Shabbos doesn't start simultaneously everywhere, there are places with no Tzeis or Neitz at all and at the poles there's no time to tell.
Then Moses had to know that the Earth is round and the Sun revolves around it and differences between time zones and latitudes. And he had to pass all that knowledge on to Neviim up to Knesset Hagdolah.
However, nowhere in our sources, this Halachicly necessary knowledge is mentioned and it is completely "lost" for millennia.
How the total lack of this knowledge through the following generations can be explained?
A lot of people are trying to prove that sages knew numerous scientific facts by interpreting their vague statements, but my point is that that knowledge should always have been a part of the Jewish Halachah starting with Moses, the fact we don't find in our sources.
