Explores evidence for dark matter in galactic rotation curves and clusters, as well as cosmological concepts like the Robertson-Walker metric and inflation.
Covers gravitational lensing in astrophysics, including deflection angle, Einstein radius, lens solution, and its application to galaxies and the universe.
Explores gravitational motion equations, energy conservation, angular velocity, orbits, relativity effects, black holes, time dilation, cosmology, and rotational equilibrium.
