SUMMARY

The discussion centers on the concept of whether our universe exists in an infinite loop within a multiverse framework. Key points include the potential for a "big crunch" leading to a subsequent "big bang," and the implications of unknown forces that could repel energy from other universes. The cyclic model of the universe is referenced, although it is noted that this theory lacks widespread acceptance among physicists. The relationship between the multiverse and the infinite loop theories is also highlighted as potentially independent.

PREREQUISITES
  • Understanding of the multiverse theory
  • Familiarity with the concepts of the big crunch and big bang
  • Basic knowledge of cosmology and astrophysics
  • Awareness of the cyclic model of the universe
NEXT STEPS
  • Research the cyclic model of the universe in detail
  • Explore the implications of multiverse theories on cosmology
  • Study the physics behind the big crunch and its consequences
  • Investigate current debates among physicists regarding the acceptance of these theories
USEFUL FOR

Astrophysicists, cosmology enthusiasts, and anyone interested in theoretical physics and the nature of the universe.

Just a question, I am by no means a astrophysicist... just a lowly thinker who doesn't think much

IF
a multiverse exists and we exist in a multiverse

AND
our universe in the end is doomed by our own gravity, resulting in "the big crunch"

AND
there will be another (or infinitely) big bang due to the crunch...

AND
if all known laws of physics do not exist at the end of the crunch

AND
that some force at this point, may exist strong enough to repel energy (visible light, micro, etc) from other universes, kinda the opposite of what a black hole does?...

what i am getting at is if this is all possible: multiverse, big squeeze, big bang... can it be possible that our universe is in a infinite loop within a multiverse?


once again I am only an occasional reader of some basic astrophysics and basic quantum so don't be too harsh...

The multiverse question and the infinite loop question are different questions and they might not be dependent on each other.

The Infinite loop universe is a theory in cosmology known as the http://en.wikipedia.org/wiki/Cyclic_model" . I don't think it's well accepted by physicist
