Haug, E.G. and Tatum, E.T. (2025) Friedmann Type Equations in Thermodynamic Form Lead to Much Tighter Constraints on the Critical Density of the Universe. Discover Space, 129, Article No. 6.

The note presents a classification of the relevant distinct types of solutions of the general Friedmann equation without assuming a priori restrictions for the parameters occurring in this equation.

This project, conducted as part of a course on differential equations in engineering (2022), focuses on solving the Friedmann equations to model the expansion of the universe by comparing numerical ...
