Where does the mass of the particle come from?
anwers this question by another question: Where does the mass of the droplets condensing from water vapor come from? If you can answer this question, you can answer the above question as well.
where does the energy come from?

AWT assumes, every question for ultimate origin of reality is missleading, because multiple histories and/or futures may exists here. Both mass, both energy is already here from its very beginning and it compensates mutually in emptiness of vacuum. Just the violation of this random equillibrium manifests itself like local excess of energy or matter.
It means, AWT doesn't solve origin of energy and matter, space or time. It simply puts all these quantities in mutual gradient driven relation, described by wave equation in which all members including number of dimensions are just infinite. The infinity state brings a lowest number of problems from causality reasons: every other particular number would introduce another questions and zero is impossible, as we know, the Universe is nonzero. After then the infinity is the first very natural choise, which doesn't require any other reasoning.
