Tell us where the laws of physics have been abridged. Forensics, the Principle of Uniformity, scientific method all seem to depend upon these principles which allow us to apply the philosophical law of logic.
As to why we will be able to discover them, I suppose one might assume that we might never discover anything. But, science is the process of discovery and of discovering causes. Scientist have been laborously working for centuries to discover an order imposed upon this universe. I suppose we could all stop that now.
(Western) scientists assume order and discoverability because of the basis of their culture - the old and new testament of the Bible.
Islamic "scientists" were severely limited by their culture, because their educational facilities saw any assumption of a consistent creation as "chaining Allah" and was viewed as apostasy.
Back to the point. Modern science is based on the SUPERNATURAL ASSUMPTION that the Creator made His creation in a logical manner that was discoverable by His special creation, mankind.
