    If the universe has sufficient overall density, it will eventually cease expanding and recollapse in a "Big Crunch."
     The universe could have existed in an infinitely large state for all eternity, with galaxies forming and dissipating continuously in a uniform manner.
     The universe could continue to expand forever at a rate that slows continuously, but never slows to a halt, even at infinite time.
     The universe could continue to expand forever at a rate that slows continuously, eventually slowing to a halt at infinite time.
