Relativity and Cosmology


Cosmology on the Back of an Envelope

Authors: John R. Berryhill

An explicit closed-form solution applicable to the lambda - CDM model has been known, or perhaps forgotten, for decades. It incorporates zero spatial curvature and a nonzero cosmological constant, as recent observations support. The model incorporating these essential points is presented here in updated form. An explicit, closed-form, solution is displayed, together with useful formulas and graphs. The presentation is accessible with first-year physics and calculus.
