You’re following the QM dogma (doctrine?) set forth by Roger Penrose, at least in the absence of gravity. I don’t agree that quarks are “imaginary” particles; their presence can be inferred from scattering experiments and in that sense they are no more imaginary than neutrinos or electron or protons or positrons… The dark matter estimate is a reasonable one, estimated from the mass required to keep galaxies rotating as they do; the dark energy estimate is, as near as I can figure out, that set up to get a flat universe. See Roger Penrose’s “Road to Reality” pp. 776,777. and is therefore, a bookkeeping device.That’s one of the reasons why I’d say observation has nothing to do with anything. When I learned the basics of QM, and I mean only the basics, we were taught that elementary particles are imaginary constructs used to further the math, and that wave/particle duality plus the absence of gravity from the theory pointed to some loose ends. That wasn’t to criticize QM and may have be bad teaching, but it left me with the impression that all current interpretations are more likely wrong than right.
On a different tack, there’s an entertaining one hour lecture for generalists (at an atheist conference, so keep your sense of humor) by Lawrence Krauss on cosmology (if you don’t want to watch it all, there’s an interesting aside for Catholics starting at minute 11). His conclusions are little more than turtles all the way down, preaching to his choir, but along the way he makes a reasonably convincing case that the energy in visible matter plus dark matter equals dark energy, hence the overall energy in the universe is and always has been zero. Thoughts?
And thanks for the reference I’ll have a peak when I’m in a tranquil mood.
