Did Universal Physical Constants Exist at the Big Bang?

Click For Summary
SUMMARY

The discussion centers on whether universal physical constants, such as Planck's constant and the speed of light, were established at the moment of the Big Bang. Participants question if the early universe existed without these constants or if they emerged simultaneously with fundamental forces and particles. The conversation highlights the uncertainty surrounding the nature of the universe's inception and suggests that variations of the universe may exist, influenced by the observer's perspective. Overall, there is a consensus that definitive answers remain elusive.

PREREQUISITES
  • Understanding of universal physical constants, including Planck's constant and the speed of light.
  • Familiarity with fundamental forces, specifically strong and weak nuclear forces.
  • Basic knowledge of cosmology and the Big Bang theory.
  • Awareness of observational perspectives in theoretical physics.
NEXT STEPS
  • Research the implications of Planck's constant on quantum mechanics.
  • Explore the role of strong and weak nuclear forces in particle physics.
  • Investigate theories on the multiverse and variations of the universe.
  • Study the observational effects on cosmological models and their interpretations.
USEFUL FOR

Physicists, cosmologists, and students interested in the foundational principles of the universe and the nature of physical constants at the Big Bang.

TL;DR
Re: the Big Bang. Were the universal physical constants already in place at the instant of the BB? Things like Planck's constant, the speed of light, the various mass of particles, the various force values.
Were the universal physical constants already in place at the instant of the BB? Things like Planck's constant, the speed of light, the various mass of particles, the various force values. Was it possible that the early universe ( the first couple of billionths of a second or so) existed without all the values we know today? Strong and weak nuclear forces? Or did they spring into existence as the same time as the forces and particles that are associated with?

It has been suggested that there could be many variations of 'the Universe',
some of which make more sense, and/or are more interesting than others.
To some extent depending on who is observing it.
Personally I am not convinced,
