SUMMARY

The discussion centers on the transition from the pre-big bang universe to the post-big bang universe, specifically questioning how physical constants can change. Participants argue that if constants can transform into new constants, they were never truly constant, suggesting a chaotic nature of laws governing the universe. The conversation highlights the lack of empirical evidence regarding pre-big bang conditions and emphasizes the speculative nature of such theories, referencing guidelines from the Physics Forums.

PREREQUISITES
  • Understanding of cosmology and the big bang theory
  • Familiarity with physical constants and their roles in physics
  • Knowledge of speculative theories in theoretical physics
  • Awareness of forum guidelines for discussing speculative topics
NEXT STEPS
  • Research the implications of changing physical constants in cosmology
  • Study the principles of speculative theories in physics
  • Examine the guidelines of reputable physics forums for discussing theoretical concepts
  • Explore the concept of the pre-big bang universe and its implications
USEFUL FOR

Physicists, cosmologists, and students of theoretical physics interested in the nature of physical constants and the implications of the big bang theory.

Just a quick question: the transition between pre-big bang to post big bang (if it occurred) required a change in physical constants (our universe is ever-expanding while the preBB universe was not). How can these constants change themsevels into new constants like that? This would seem to require laws which are defined by "constants" that could change into new constants. Meaning that they weren't constants in the first place, and thus the laws were variables/chaotic laws incapable of governing any sort of meaningful process. This is contradictory to our universe which IS governed by established laws and universal contsants.

Is there any physics explanation for this?

Since we have no information about "pre-big bang", how are you able to know that it "required a change in physical constants"? How do you KNOW that such physical constants even existed?

I would strongly recommend you review the https://www.physicsforums.com/showthread.php?t=5374" that you had agreed to. Play particular attention on speculative theory. Since your post/question will require A LOT of such speculative answers, this thread simply cannot be addressed without violating our Guidelines.
