Is cyclical cosmology, the idea that everything repeats over and over again, the simplest cosmology? If not, what are some simpler cosmologies?
How is a cycle simpler than a straight line?
One-shot cosmologies are naturally simpler logically in several ways:
- They are robust relative to perturbance and chaotic attraction since they do not require things to line up perfectly at the start and end of a cycle
- They do not produce a large number of entities (everything in the whole next cycle) that cannot be accessed or tested for in our current universe
- They can exist with or without conservation laws
- They allow for the things we currently observe going in a single direction (like spatial expansion and entropy increase) to really just continue forever, without somehow 'correcting' for going 'too far'.
The simpler solutions just feel bad because of Kant's antinomy on the start and end of time. We have a conceptual problem with the start and end of time, and we transfer this difficulty onto the start and end of human consciousness, finding it difficult or insulting to imagine consciousness first arising, or 'the soul' ending. But those could just be our problems, and not the universe's.
A single point that escapes our intuition and bothers us in a vague way is not additional complexity in the same way rigid conservation laws or multiplication of entities is.
