SUMMARY

The discussion centers on the implications of the dodecahedron model of the universe, as proposed by Spergel and Weeks, particularly regarding the density of matter and its curvature. The model predicts a density measure of 1.013, suggesting a nearly flat universe, while current observations from WMAP indicate values between 1.00 and 1.04. The conversation highlights skepticism towards the "six matching circles" requirement and suggests that if the finite model is validated, it would invalidate several cosmological theories, including the eternal inflationary universe and the brane collision model. The participants express a strong belief that future observations will refine these measurements closer to 1.0535.

PREREQUISITES
  • Understanding of cosmological models, specifically the dodecahedron model.
  • Familiarity with WMAP (Wilkinson Microwave Anisotropy Probe) findings.
  • Knowledge of density parameters in cosmology, particularly omega (Ω).
  • Basic grasp of microwave background radiation and its significance in cosmology.
NEXT STEPS
  • Research the implications of the dodecahedron model on current cosmological theories.
  • Study the methodology and findings of WMAP regarding cosmic microwave background radiation.
  • Explore the concept of density parameters and their role in determining the universe's curvature.
  • Investigate alternative cosmological models that may be affected by the findings discussed.
USEFUL FOR

Astronomers, cosmologists, and physics enthusiasts interested in the structure and fate of the universe, particularly those examining the implications of finite models in cosmology.

Just wait until next month and it will be a hotdog (or something else).

From the article:
"Spergel and his team are now working with Weeks to see if they might somehow have missed the circles. And there is a further test of the dodecahedron model. It predicts that a key measure of the density of matter in the Universe, which governs its curvature, is equal to 1.013.

Completely flat space corresponds to 1, while values greater than or less than 1 would create a curved Universe. Observations of the microwave background radiation so far suggest the value lies somewhere between 1.00 and 1.04. Further observations by WMAP and other instruments should give a more accurate answer within the next few months."

From this, and other observations, I'll go with Weeks and not Spergel. I just don't buy the "six matching circles" requirement.

This has some implications for other cosmological models. If this finite model is correct, then several others are ruled. An eternal, inflationary universe is in the toilet, and the brane collision model also comes to mind.
 
how did they figure this out? radio signal?
 
as i understand the the universe would have to have
2/3 more mass to be "closed", do these observations
override predicted criticle mass?
 
WMAP findings among others suggest omega is close to 1. However, the observable matter in the universe is only a third of that number. Hence the notion of matter that does not produce EM radiation.

I suspect it will be shown as closer to 1.0535. And another thought...how to configure a finite universe by an infinite pi value?
