There are three possible fates for the universe: 1. eternal expansion; 2. total collapse; or 3. some equilibrium condition with no further motion. What conditions might favor one result over the other?
A) Critical velocity—is there enough momentum to continue expansion forever? B) Critical density—is there enough mass in the universe to cause gravitational collapse? C) Critical volume—is the universe large enough for unlimited expansion? D) Critical energy—is there enough energy in the universe to maintain either expansion or collapse?
