    2. This is primarily a supplement/complement to Liddle, Ch. 8: The Cosmological Constant, also to Liddle, Ch. 9: The Age of the Universe, Liddle, Ch. 17: Classical Cosmology: Distances and Luminosities, Liddle, Ch. 20: Structure of the Universe, and Liddle, Ch. 21: ConstrainingCosmological Models.

    We're just going to surf stuff including the Web.
