Jenny Wagner: What If We've Been Wrong About Dark Matter For Decades?

Every episode days early, ad-free, plus my essays: https://curtjaimungal.substack.com/subscribe

Jenny Wagner on the inverse problem: mapping dark matter without assuming what it is.What if 85% of the universe's matter isn't missing, and our models were never clean enough to know? Wagner proves mathematically that every dark matter map is extrapolation. The data tells you only what is local. The rest is a model assumption dressed as evidence. She ties this to Einstein's 1917 warning, that homogeneity and isotropy were always a placeholder, never a truth, and argues cosmology is not in crisis. It's finally ready for more detail.
