The Big Crunch is a theoretical scenario concerning the ultimate fate of the universe. Here are key ideas that describe the Big Crunch:

  1. After the universe reaches its maximum rate of expansion, gravitational forces will begin to dominate, causing the universe to decelerate and eventually collapse back in on itself.
  2. The universe would enter a phase where all matter and energy, instead of continuing to expand, would start to contract, leading to a singularity similar to the state that existed before the Big Bang.
  3. This process may result in the universe going through cycles of expansion and contraction (also known as oscillating universe models), where it expands to a certain point and then collapses, only to potentially expand again.

Your statement regarding "the universe is not only composed of the objects that we can" seems incomplete, but it usually relates to concepts like dark matter, dark energy, or the total mass-energy content of the universe, which could also influence the dynamics of expansion and contraction. However, the core ideas of the Big Crunch focus primarily on gravitational collapse after a phase of expansion.
