SUMMARY

The discussion centers on the theoretical implications of the universe being modeled as a manifold with a boundary. Participants emphasize that the appearance and characteristics of such a boundary depend entirely on the boundary conditions imposed. However, there is a consensus that current scientific evidence does not support the existence of a boundary in the universe, nor is there a working model that incorporates this concept.

PREREQUISITES
  • Understanding of manifold theory in mathematics
  • Familiarity with boundary conditions in physics
  • Basic knowledge of cosmology and the structure of the universe
  • Concepts of theoretical physics and models
NEXT STEPS
  • Research manifold theory and its applications in physics
  • Explore boundary conditions in general relativity
  • Investigate current cosmological models and their implications
  • Study the implications of a boundary-less universe in theoretical physics
USEFUL FOR

The discussion is beneficial for theoretical physicists, mathematicians specializing in geometry, and cosmologists interested in the fundamental structure of the universe.

what would the universe look like if its a manifold with boundary? what would it look like at the boundary? and what happens if u try to touch the boundary? is it just a black wall that's unbreakable?

This would depend on what kind of boundary conditions you impose. As far as we can tell though, there is no evidence whatsoever to imply a boundary.

There's no working model of the universe with a boundary.
