A cosmological model in which the universe has a finite volume but no boundary, with enough mass density to eventually stop expanding and begin contracting, leading to a 'Big Crunch'.

    A model of the universe in which space is finite but unbounded, and the universe will eventually stop expanding and begin to contract.

    • In a closed universe, the total density of matter and energy is greater than the critical density.
    • The closed universe model predicts a Big Crunch at the end of its cycle.
    • Einstein's equations allow for a closed universe with positive curvature.
