The result? A_CB = 0.42⁺⁰⋅⁴⁰₋⁰⋅³₄ × 10⁻⁴ Consistent with zero at ~2σ. No detection—yet. But it’s the tightest constraint to date on anisotropic birefringence. And no one dataset dominates, which adds robustness.

What’s next? The Simons Observatory, CMB-S4, and LiteBIRD could lower uncertainties by 10×. That means we might finally detect a twist in the cosmos—or rule it out with confidence. Either way, we’re getting closer. Follow The INTO THE IMPOSSIBLE Podcast briankeating.com/podcast

I’ve spent years searching for evidence that the universe might have a preferred direction—something that would shake the foundations of cosmology. Our new paper just dropped in Physical Review D. It’s about a strange twist in the cosmic microwave background: anisotropic birefringence.

A great effort done with CNR in the #DestinE project. Read to discover how the software is used in the Climate Digital Twin and how it could be useful for other projects as well!
