A new thread titled Boson Space might interest you. In a response to David's thread I provide some coincidental ideas which might answer this question.

Think strings.

Higher energies are generated by higher frequencies. In order to establish a three dimensional framework for reality to exist space must first be defined and this represents the very first phase of "reality building", ie. the very first quantum threshold crossed represented by the composite wave occupying that band of the reality spectrum which establishes the homogeneous construct of bosons that is space-time, after which progressively lower frequencies representing more massive force and eventually matter particles are generated, possibly as subharmonics of that fundamental string frequency composite, but each occupying a unique niche in the cosmic scheme of things.

Acelleration provides empirical evidence that increasing mass slows time, and that is a principle of quantum dynamics.
