Why is it that people like the prophets, and other, more modern figures who are seen as being divinely inspired (the kabbalists, the Chasidic rebbes, etc.) never seem to be told secrets of science, nature, and other testable facts?
If they can learn from G-d the most esoteric details of the architecture of the soul and the attributes of HaShem Himself, surely they should be easily able to get information like how to cure diseases, how to prolong human lives, and how to build, say, an indestructible ship. They should be able to quickly learn answers to the practical and theoretical questions that are being tackled by science. But we never hear about anything like that. Why not?
Even as I write this question, I am aware of several stories from the Prophets and the Writings that seem to contradict its premise. But most of the examples I can think of--not having read everything--are of Hashem providing practical guidance in a single situation, not revealing knowledge of the natural world as could be presumably ascertained by science. Please forgive my lack of knowledge if I have truly missed anything; that's part of what this question is for!
