Kant: Metaphysics vs. Math and Science

Math and Science have limits wheras metaphysics has bounds. Math and Science are complete in themselves and there are no questions that are left unanswered with enough time, insight, and progress. Metaphysics is bounded and reason offers questions up to itself that it can't answer. Metaphysics asks questions about the nature of things themselves. In other words, metaphysics raises questions that could possibly left unanswered given alot of time and insight. However, all questions given by math and science have a final point or answer.
