Since you want to make mass the central concept of your grand theory, study how the Higgs mechanism is supposed to work and see if you find it acceptable.If not, how do I go about it?

with the standard model of particle physics

Standard Model is fully campatible with special relativity.

Standard Model is fully campatible with special relativity.

Correct. The much harder part is reconciling general relativity (i.e. gravity) with the Standard Model. There is also no consensus solution to explaining dark matter, although there are several viable theories that are consistent with all available evidence to a reasonable extent that may be salvageable. Dark energy can be fully explained with the cosmological constant, although tensions between this very simple model and the data are growing and now approach three sigma. Many alternative dark energy theories have been proposed, most of which are viable to explain that one question.

Comparison of dark energy models after Planck 2015

Yue-Yao Xu, Xin Zhang

We make a comparison for ten typical, popular dark energy models according to theirs capabilities of fitting the current observational data. The observational data we use in this work include the JLA sample of type Ia supernovae observation, the Planck 2015 distance priors of cosmic microwave background observation, the baryon acoustic oscillations measurements, and the direct measurement of the Hubble constant. Since the models have different numbers of parameters, in order to make a fair comparison, we employ the Akaike and Bayesian information criteria to assess the worth of the models. The analysis results show that, according to the capability of explaining observations, the cosmological constant model is still the best one among all the dark energy models. The generalized Chaplygin gas model, the constant w model, and the α dark energy model are worse than the cosmological constant model, but still are good models compared to others. The holographic dark energy model, the new generalized Chaplygin gas model, and the Chevalliear-Polarski-Linder model can still fit the current observations well, but from an economically feasible perspective, they are not so good. The new agegraphic dark energy model, the Dvali-Gabadadze-Porrati model, and the Ricci dark energy model are excluded by the current observations.
