Yes, that is an example, but it is not limited to gravity. The reasons I am reluctant to say that it is mass is because if I did, then it would have to follow certain laws and rules, like the law of conservation of mass. I believe that it is ultimately energy, and the things it does mimick matter. But if it were matter, it wouldn't explain how Specialization works.
