relativity-astrophysics
From the author
Relativity and astrophysics from special relativity through cosmology. Covers Einstein's postulates, time dilation, length contraction, Lorentz transformations, relativistic momentum and energy (E=mc^2), spacetime diagrams, the equivalence principle, curved spacetime (conceptual), gravitational lensing, black holes (Schwarzschild solution, Chandrasekhar limit), stellar evolution (main sequence through supernova), and cosmology (Big Bang, Hubble's law, CMB, dark matter, dark energy, FLRW metric). Use when analyzing systems at relativistic speeds, strong gravitational fields, stellar lifecycles, or cosmological scales.
