SUMMARY

The discussion centers on the hypothesis that the Big Bang could be a cyclical event facilitated by black holes. Participants propose that black holes may contribute to a massive contraction of matter, potentially leading to another Big Bang. The conversation explores the implications of black holes' gravity and the existence of white holes, questioning whether the universe can gather enough mass for re-contraction after expansion. Key calculations regarding the distance at which re-contraction becomes impossible are also highlighted.

PREREQUISITES
  • Understanding of black hole physics and their gravitational effects
  • Familiarity with cosmological theories, including the Big Bang and cyclic models
  • Knowledge of white holes and their theoretical implications
  • Basic principles of space-time and cosmic expansion
NEXT STEPS
  • Research the concept of cyclic cosmology and its implications for the universe
  • Study the properties and behaviors of black holes in detail
  • Explore the theoretical framework of white holes and their role in cosmology
  • Investigate mathematical models for calculating cosmic expansion and contraction
USEFUL FOR

Astronomers, physicists, and anyone interested in advanced cosmological theories, particularly those exploring the nature of black holes and the universe's cyclical potential.

Could the Big Bang Have Been A Cyclical Event?

I am a layperson...this is a long-pondered question.

Is it possible that Black Holes serve a greater purpose...to facilitate a massive contraction...which will then lead to another big bang?

It's logical that the Big Bang was precipitated by a contraction. It would explain the consistency of matter. All matter could have been mixed together in a single contractive gathering of massive black holes...reached a critical point and exploded outward. The explosion could have also created new and smaller black holes...that would continue to grow as they travel outward (also - are all black holes shaped the same?). If the black holes could become massive enough they could re-gather and the cycle could be repeated infinitely.

The question is this...as the Big Bang started with a finite quantity of mass...and continues to expand infinitely...would there ever be enough mass concentrated in expanding and outwardly traveling black holes that would allow a re-contraction? Or, is the space/time of expansion too great to provide for a gathering and re-contraction?

How can this be calculated...at what distance will/did a re-contraction become impossible?

Interesting theory... but I'm not sure if that would even work. Black Holes have gravity so strong, that it destroys what ever goes in. So nothing actually 'builds up' in them.
And there are also theories of the existence of White Holes, which essencially are the opposite of Black Holes. Instead of sucking things in, they push them away.
 
When the black hole destroys whatever it pulls in and turns the matter into energy...isn't the gravity strong enough to hold that energy in the form of a magnetic field?
