I’m not the one that keeps ignoring that GR has been tested to a 99.8% accuracy in the solar system without one spec of Fairie Dust.... then thinks adding 96% Fairie Dust to a theory already tested to a 99.8% accuracy is ok....
I assume you are talking about dark matter here.
Yes, one of the BIG constraints on both dark matter and alternatives is that we know what works in the solar system so well. For dark matter, the local density is small enough to not have affected the observations. If you want a scientific paper discussing this, I can provide one.
Alternatives to dark matter, such as MOND and TeVeS, also are subject to the constraint that they need to work at the level of the solar system. This was one of the big constraints in formulating alternatives to dark matter by considering different 'laws of gravity'.
Why do you keep ignoring its accuracy?
Nobody ignores it. In fact, it is one of the constraints to any model for galactic rotations that is proposed.
GR by the way breaks down at the event horizon of every mythical black hole. The math you claim supports you does just the opposite since the energy tensor is set to zero, declaring their is no other mass in the entire universe but that of the singularity. It’s what made the BB a scientific possibility to begin with, hence singularity. But you ignore that very math you claim to follow and insert them by the billions, despite the energy momentum transit being set to zero in all solutions, demanding no other mass exists but that of the singularity.
No, that is not *at all* what the math for the BB theory does. Quite the opposite, in fact. The basic assumption for the BB models are that GR works and that the universe is isotropic at any time (so the density is not zero everywhere--it is constant everywhere). That produces, via the math, either an expansion or a contraction. In the expansion, the density decreases over time, but has an infinite limit as t-->0. This is what is meant by a singularity: some variable goes to infinity as we approach a situation.
Please, you understand the math not at all or you would accept the very reason the BB was a possibility to begin with, because the math demands the singularity is the only mass that exists in the universe....
Let's see the math, then. I am a mathematician, so I guarantee I can understand it.
