1. Dark Matter Evidence: Rotation Curves

Question:
The observed rotation curves of spiral galaxies (velocity vs. radius) remain flat or even rise at large radii, while Keplerian motion predicts a decline ($v \propto r^-1/2$). Explain this discrepancy and show how it leads to the dark matter hypothesis.

From Star Clusters to Supermassive Holes: Physics Solutions to Galaxy Discussion Questions

Galaxies are "island universes" containing (10^7) to (10^12) stars, gas, dust, and dark matter. While observational astronomy catalogues their shapes, physics seeks to explain their motion, stability, evolution, and central engines. Below, we tackle common discussion questions that bridge Newtonian gravity, statistical mechanics, and general relativity. Report: Physics of Galaxies – Key Discussion Questions
