What if no more than 7 Poincare-group generators correlate with behavior of the Z and W bosons? Or, of the hypothetical graviton?

A fuller statement of the question: What consequences arise (regarding nature or theories) if some of the 10 Poincare-group generators do not correlate with behavior of Z and W bosons, and/or...

Is there any evidence m_neutrino is not 0.09161 eV/c^2?

My attempt at theory indicates m_neutrino ~ 0.09161 eV/c^2 - for all three neutrinos. The relevant result is (m_neutrino)*(m_tauon) ~ {(m_electron)^2}*{(alpha)^(3/2)}. Here, alpha is the...

How many flat space-like and flat time-like dimensions does it take to embed space time?

Curved space time has 4 dimensions. Mathematically, such a 4-dimensional space embeds in a flat space of no more than 10 dimensions. To what extent do observations or theories suggest answers to...

How does the ratio of dark energy to baryonic matter evolve over time?

What is the time dependence of the evolution of the observed ratio of dark energy to baryonic matter? The density-of-the-universe ratio varies from about (zero):1 at approximately 380,000 years...

Are 1 : 5 : 18 the ratios of baryonic matter : dark matter : dark energy? If so, why?

Astrophysical observations seem consistent with these ratios of "densities of the universe." http://vixra.org/abs/1206.0049 (attached) posits theory predicting these ratios. It also provides the...
