Why is there any residual angular momentum left over from the big bang

Click For Summary
SUMMARY

The discussion centers on the existence of residual angular momentum in the universe from the Big Bang. Participants question the definition of global conserved angular momentum and its measurement beyond the observable universe. The conversation highlights that while galaxies possess angular momentum, its origins differ from that of the universe's initial conditions. The implications of the Anthropic principle and statistical analysis of angular momentum in the early universe are also explored.

PREREQUISITES
  • Understanding of angular momentum in physics
  • Familiarity with the Big Bang theory
  • Knowledge of the Anthropic principle
  • Basic concepts of cosmology and the observable universe
NEXT STEPS
  • Research the definition and implications of global conserved angular momentum
  • Study the Anthropic principle in the context of cosmology
  • Examine statistical methods used to analyze angular momentum in astrophysics
  • Explore the origins of angular momentum in galaxies and their formation
USEFUL FOR

Astronomers, physicists, cosmologists, and anyone interested in the fundamental properties of the universe and its formation.

Hi,

I'm basically wondering why there is any residual angular momentum in the universe left over from the big bang at all. Can this be explained by the Anthropic principle and could statistics surrounding angular momentum tell us anything about the early universe?

Cheers,
Taylrl

Be careful with all the things your question implies:
How do you define a global conserved angular momentum, where do you see this angular momentum today (and how do you measure it beyond the borders of the observable part of the universe?), and why do you expect zero initial angular momentum?

Galaxies have angular momentum, but that has a different origin.
