A Convenient Way to Explain Metaphysical Modality

Consider the following question: could the laws of nature have been different?

According to physical modality, the answer is trivial: no, of course the laws of nature could not have been different. After all, physical modality just is the range of what is the modal space governed by the laws of nature.

According to logical modality, the answer is similarly trivial: yes, of course the laws of nature could have been different. After all, there is nothing logically incoherent about the idea that, say, the speed of light could have been slightly faster or slower than it in-fact is. 

Metaphysical modality, then, is that form of modality which renders non-trivial the question "could the laws of nature have been different?"
