How much physics have we discovered, of all there is to discover?
Prediction market on manifold. If you believe we haven't discovered anything about physics, bet towards 0. If you believe we already know everything there is to know about physics, bet to 100%. This market is intentionally vague, under-specified, and open to interpretation. It will probably never resolve.
