A similar question was closed, but I'm going to elaborate on it:
It is universally accepted that after the principle was accepted (B"M 59b) in times of R' Eliezer, the Rabbis have the power to rule Halachah against the Heavenly truth.
As we also know that they have the power to kill even when the Torah doesn't require capital punishment (עונשים שלא מן הדין, Sanhedrin 81b).
My other question, ("why-did-sanhedrin-deal-with-who-has-a-share-in-olam-habah", showed that Rabbies did deal with areas other than Halachah Lemaaseh and openly argued with Heavens. And many Poskim rely on this Gemmorah to prove, for example, that setting a person's share in the WTC can be done by a Beis Din (thanks to @IsraelReader's answer and see the discussion there) obligating Heavens to follow.
What, then, are the limits of the Rabbinical power, based on this principle:
- can they free a person from Hell, by deciding he's a Tzadik? Can they decide on reincarnation or resurrection?
- can they rewrite history, denying or altering the historical events from the Torah?
- can they change Kabbalistic concepts, like swapping Tifferes and Yesod, adding or subtracting Sfiros?
- can they change the flow of the Geulah, deciding on how it will occur and when?
I searched for information on this principle but I didn't see anybody clearly defining the limits. I understand the information is scarce, but I'm looking for sources that might speculate on extrapolating the principles on areas I mentioned or explicitly denying it.
