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

I personally subscribe to The Economist. TOE listeners get 35% off the annual subscription. No other podcast has this! https://economist.com/TOE Jenny Wagner examines the inverse problem: how to map dark matter without assuming what it is.What if 85% of the universe's matter isn't missing — it's just that our models were never clean enough to know? Wagner proves mathematically that every dark matter map ever made is extrapolation. The data only tells you something local. Everything else is a model assumption wearing the costume of evidence. She connects this to Einstein's own 1917 warning — that homogeneity and isotropy were always a placeholder, never a truth — and makes the case that cosmology is not in crisis. It's finally ready for the next level of detail.
