SUMMARY

The discussion centers on the concept of the Big Crunch and its implications for the universe's future. Participants agree that current data indicates a Big Crunch is highly unlikely due to the universe's accelerating expansion. They emphasize that initial conditions alone cannot predict future outcomes, aligning with mainstream interpretations of quantum mechanics. The conversation also touches on the symmetry of the universe and the unresolved nature of dark energy and the cosmological constant.

PREREQUISITES
  • Understanding of quantum mechanics interpretations
  • Familiarity with cosmological concepts such as the Big Crunch
  • Knowledge of dark energy and the cosmological constant
  • Basic principles of wavefunction symmetry in physics
NEXT STEPS
  • Research the implications of dark energy on cosmic expansion
  • Study quantum mechanics and its interpretations in cosmology
  • Explore the concept of wavefunction symmetry in the universe
  • Investigate current theories regarding the fate of the universe
USEFUL FOR

Astronomers, physicists, and anyone interested in cosmology and the future of the universe will benefit from this discussion.

after the big crunch occurs would everything be the exact same until another big crunch

Academic is completely correct, even if the initial conditions were identical there is no reason the outcome should be.

But it's a moot point, since current data quite definitively shows that there will be no big crunch for our universe.
 


the possibilities of big crunch is impossible to current under standing. b/c the universe it accelerating
 


That doesn't mean its impossible, just very unlikely. Again, you cannot predict what will happen from initial (or current) conditions alone. :) It goes both ways.
 


We could have big crunch in the past.
I like the idea that universe is symmetric, Universe wavefunction W is even: W(-t) = W(t)
 


Unless the universe exists as a single structure with only one "bang" and "crunch", see the points about initial conditions.

Nabeshin: Unlikely, but not impossible, and until there is a satisfactory explanation for the cosmological constant or dark energy, it is merely unlikely, not definitive.
