Let’s talk about redshift and its causes from the perspective of the Neoclassical Physics and Quantum Gravity model. NPQG leads to an in-depth and insightful understanding of redshift, or more generally photon energy transactions.
We can now say with confidence that we have a new parsimonius model for BL-LACs: Planck plasma terminus. No more bending over backwards to model BL-LACs as being aimed towards the observer to explain the superluminality. Nope. The jet may truly be superluminal. General relativity DOES NOT APPLY to Planck plasma and it pierces spacetime.
