What are natural laws? How do scientists test them? Is time illusory or real? Do black holes make the universe expand? These questions were posed at a recent workshop for philosophers and physicists. "Why should nature be governed by laws? Why should those laws be expressible in terms of mathematics? Why should they be formulated within space and time?
