A Unified theory of Superman's Powers

Here's the abstract of a new paper seeking to explain Superman's powers:

 

In this paper we propose a new unfied theory for the source of Superman's powers; that is to say, all of Superman's extraordinary powers are manifestation of one supernatural ability, rather than a host. It is our opinion that all of Superman's recognized powers can be unified if His power is the ability to manipulate, from atomic to kilometer length scales, the inertia of His own and any matter with which He is in contact.
