Discussion Overview

The discussion revolves around the concept of whether there was more than one Big Bang, exploring various theories and implications related to the origins and evolution of the universe. Participants raise questions about the nature of time, the possibility of multiple Big Bangs, and the interactions between different universes or bubbles, touching on theoretical frameworks like Chaotic Inflation and the Big Bounce.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants question if there could be multiple Big Bangs, suggesting the possibility of two, three, or even billions of them.
  • There are inquiries about the nature of time in relation to multiple Big Bangs and whether one could be larger than another.
  • Some participants propose that collisions between different Big Bang bubbles could lead to unique interactions, potentially resulting in different evolutionary paths for forces and constants.
  • References to Chaotic Inflation theory and Big Bounce are made, with some participants expressing curiosity about their implications and interrelations.
  • One participant suggests a cyclical model of the universe, where gravitational forces could lead to a re-collapse into a singularity, potentially resulting in a new Big Bang.
  • Another participant raises concerns about the implications of a temporally finite universe and the philosophical questions it raises regarding pre-existing states.
  • There is a request for beginner readings on quantum mechanics and clarification on concepts like "Quantum foam" and its relation to "background space-time foam."
  • Some participants caution that theories discussing events before the Big Bang are speculative and lack direct evidence.

Areas of Agreement / Disagreement

Participants express a range of views, with no consensus on the existence of multiple Big Bangs or the implications of such a concept. The discussion remains unresolved, with competing theories and interpretations presented.

Contextual Notes

Some claims rely on speculative theories that lack direct evidence, and there are unresolved questions regarding the definitions and implications of concepts like quantum foam and the nature of time in relation to the universe's origins.

Was there only 1 big bang? Why not 2 or 3 or billion ?
Please don't flame me - I'm not physicist, I'm just curious :)
Thanks very much for attention.
 
Space news on Phys.org
If there can be more than 1...
Was there a time?
Can be one bigger then another?
What will happen when their bubbles collide?
Can there be different evolution of forces? or can there be different forces in different big bang bubbles ?
How they possibly will interact if they meet each other?

WOW this was old and so interesting:)
 
I have read about the Chaotic Inflation theory and Big Bounce, also about the Quantum foam but... there's many new words for me as u may guess.
Can u give me readings for beginners about quantum mechanics or anything that can help me understand? also i have some other questions -
Is the Linde "background space-time foam" the same thing as "Quantum foam" devised by
John Wheeler?
And from Big Bounce theory objections - "Furthermore, it remains a possibility that a better understanding of quantum foam may result in a re-interpretation of the evidence regarding the fate of our universe." can this lead back to Chaotic Inflation theory?
And from Chaotic Inflation theory - "Each universe within the multiverse can have a different set of constants and physical laws." can they mix?
Oh i hope that these things are not so complicated as interesting xD

There's only one that we see. There's no reason whatsoever why it has to be the only one.
 
My view is that matter and energy has always existed, and did not appear out of a vaccume or nothing. Space itself may have infinite volume, but there appears to be a finite amount of matter and energy within this infinite space.

The big bang implies that all matter and energy at one point was condensed into a singularity that exploded scattering the finite amount of matter and energy through out infinite space.

I imagine we have this expansion, and gravitational centers form as matter starts to recombine into stars and black holes. Eventually certain points within the Universe will start to form massive gravitational points causing a retraction of matter into these centers as they start to consume all matter.

This form of gravitational decay eventually starts to slow expansion and the intensity of these super gravitational systems, black holes will eventually recombine to one massive point in the Universe that will become the new point of singularity where by everything will swirl around like a toilet flushing in this final vortex and the singularity can form once again.

Another big bang, and the process could repeat for infinity. If this is true, we might be able to calculate the time of expansion, the collapse of systems into gravitational hot spots, the recombining of these hotspots into a massive center.

It may take 37 billion years, 109 billion years, I am not sure how to calculate that math because I really don't know the finite volume of matter vs the gravity it creates to affect the current expansion into contraction. I'm sure someone will get it if it's true.
 
I think it ducks the big issue. A cyclical universe is aesthetically pleasing, but, does not really answer the question. A temporally finite universe raises disturbing issues. It implies a pre-existing state beyond our ability to comprehend. I am content with that explanation.

I'm not qualified to give you in depth on these topics, but one thing I will point out is that any theory that talks about before the big bang is, at this point, extremely speculative. If there is a way to describe an outcome of the theory coherently, then it is "possible" in the sense that none of these theories have any direct evidence to support them.
