after we die, according to Buddhist and other philosophies we will be reborn.
in the new world of our birth, will it remain in this reality? i.e. earth, sun, mars, mercury, etc? or will we shift solar systems, or what if the universe and its principle don't exist anymore and gravity and mass are not variables constant or dependant, they don't even exist and are even replaced? What if the principle of which we define life are completely scrapped and we are not even corporeal because mass isn't a thing. What if everything is the same but our morals and sociology is completely different? that the justice system was replaced with an abstract currency of sorts?
food for thought.
