"Our Technologies Establish the Truth of many of our Scienttific Laws." Is there any Comparable means of Establishing Moral Rules and Norms?

Throughout the history of science, there have always been experiments to verify scientific theories. For example, after having cried "Eureka", Archimedes would have set about confirming that the weight of a body immersed in fluid is equal to the weight of the fluid it has displaced . However, when Newton thought that an object's acceleration due to gravity was constant, he could not easily test this at the time. When Einstein conjectured that energy and mass are in fact the same thing in different forms, there was, due to a lack of technological expertise, no experiment to verify this.…
