Difference between oscillatory/cyclic model and big bounce?

Click For Summary
SUMMARY

The discussion clarifies the distinction between the Big Bounce theory and oscillatory/cyclic models of the universe. The Big Bounce posits a single bounce event following a universal singularity, while oscillatory models suggest multiple bounce events, potentially infinite in number. Both theories propose re-expansion from a singularity, but their fundamental differences lie in the number of bounce events considered. This differentiation is crucial for understanding the ultimate fate of the universe.

PREREQUISITES
  • Understanding of universal singularity concepts
  • Familiarity with quantum forces and their implications
  • Knowledge of cosmological models, specifically cyclic models
  • Basic grasp of the ultimate fate of the universe theories
NEXT STEPS
  • Research the implications of universal singularities in cosmology
  • Explore the mechanics of quantum forces and their role in cosmic re-expansion
  • Study various cyclic models and their predictions for the universe's future
  • Investigate the Big Bounce theory in detail, including its mathematical formulations
USEFUL FOR

Astronomers, physicists, cosmologists, and anyone interested in the theoretical frameworks explaining the universe's evolution and ultimate fate.

If a Big Bounce can occur "after a universal singularity is reached or a repulsive quantum force causes re-expansion" then what differentiates it from oscillatory/cyclic models if both of them defend that the universe will re-expand from a singularity or before that?

The Bounce only assumes a single bounce event (there may be more, but only one is necessary). Cyclic models include a large number of bounce events (possibly an infinite number).
