SUMMARY

The shape of the universe is a complex topic that raises questions about its finite or infinite nature. Discussions highlight that if the universe is finite, it may possess a definable shape, such as a sphere or cube. Conversely, if the universe is infinite, traditional geometric concepts may not apply, suggesting it could have a non-geometrical form. This indicates that our current understanding of geometry may be insufficient to describe the universe's true appearance.

PREREQUISITES
  • Understanding of cosmology concepts, particularly the finite vs. infinite universe debate.
  • Familiarity with basic geometric principles and their application in physics.
  • Knowledge of current theories regarding the shape of the universe, including spherical and non-geometrical models.
  • Awareness of the implications of geometry on the understanding of cosmic structures.
NEXT STEPS
  • Research the implications of an infinite universe on cosmological models.
  • Explore the current theories on the shape of the universe, including spherical and toroidal models.
  • Study the limitations of traditional geometry in describing cosmic structures.
  • Investigate the role of observational data in shaping our understanding of the universe's form.
USEFUL FOR

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

what can the shape of universe be? is it sphere or cube or some bubble like shape?

Aren't you, by using the word "shape" implicitly assigning a finite size to the Universe? For surely if it has a finite size it would seem logical to assume it has some kind of finite "shape". But if the Universe is not finite, at least not in our ordinary sense of the meaning of finite, then perhaps "shape" is an inapplicable metric. And if "shape" is inapplicable, that is, what it might look like if we were to go outside of it and look at it, then perhaps its true appearance cannot be described by our currently accepted methods of geometry and thus a possible answer to your question is "if the Universe is infinite, it may have a non-geometrical form and thus no shape."
