Everything we thought we knew about the universe is built on something that doesn’t exist. For 90 years physics has assumed the universe is filled with invisible dark matter — five times more abundant than everything we can see, touch, or measure. Every galaxy simulation. Every cosmological model. Every structure formation calculation. All of it built on dark matter being real. No dark matter particle has ever been detected. Not once. In 50 years. Billions of dollars. The most sensitive detectors ever built. Nothing. This paper proposes why. It isn’t there.
