Jenny Wagner: What If We've Been Wrong About Dark Matter For Decades?
Jenny Wagner, an astrophysicist who specializes in gravitational lensing and inverse-problem methods, questions whether dark matter maps are mostly model-driven. She explains how lensing yields only local information. Short, punchy takes cover lensing degeneracies, model-independent reconstruction, challenges to common halo assumptions, and implications for cosmology’s foundational principles.
