Some Important Introductory Concepts
... Kepler’s 3rd law, as modified by Newton (coming up), will be a cornerstone of much of this course, because it allows us to estimate masses of astronomical objects (e.g. masses of stars, galaxies, the existence of black holes and the mysterious “dark matter”).
