What Fundamental Invariance Principle is Violated by FSC Anisotropy?

[hyksos]

If the Fine-structure constant was measured to deviate in the sky , and this deviation was directional, which fundamental invariance principle would be violated?

Quasar survey by VLT has observed deviations in the FSC that appear to be locked against directions of distant galaxies.

Galaxy cluster surveys corroborated the anisotropy , and were performed by an independent group

Which particular fundamental symmetry is violated by these findings? Poincare symmetry? Lorentz invariance? Something else?
Your thoughts?

Based on the information provided, it seems that the fundamental symmetry that is being violated by these findings is Lorentz invariance. This principle states that the laws of physics should remain the same for all observers moving at constant velocities, regardless of their direction or speed. The fact that the deviations in the Fine-structure constant are directional and appear to be locked against directions of distant galaxies suggests that there is a preferred direction in the universe, which goes against the principle of Lorentz invariance. This could potentially have significant implications for our understanding of the fundamental laws of physics and the structure of the universe. Further research and investigation will be needed to confirm these findings and understand their implications.
