Thanks Catholic Scientist!
Obviously a cyclic universe implies infinity as long as energy isn't being lost.
Since the Big Crunch leads us back to a singularity I will assume it could then lead to another Big Bang potentially starting another cycle and could go on for infinity as long as energy isn't being lost. Even if energy was being lost it would seem like an infinite amount of energy could never be lost. If it is measurable it could be lost...right? I guess if energy was being lost there might come a time when the cycle would stop when there wasn't sufficient energy to create a Big Bang and end in infinite singularity.
What about the other two...Big Rip and Heat Death?
Can you tell me if the "death" of the universe in these two theories implies nonexistence? Or does this imply breaking down into it's smallest parts and lacking energy? When the energy is gone and matter is gone does the space it occupied cease to exist?
Which of these is the most popular theory of today?
I think therefore I am...busy
