The universe doesn't have volume from outside?

Click For Summary
SUMMARY

The discussion centers on the concept of the universe's volume and its perception from an external viewpoint. One participant argues that if the universe were observable from outside, its shape would indicate whether it is finite or infinite. The opposing view asserts that the universe is defined as space itself, making any external observation irrelevant. The consensus emphasizes that the universe cannot be viewed from an outside perspective, as there is no defined "outside" to the universe, reinforcing its infinite nature.

PREREQUISITES
  • Understanding of cosmology and the nature of the universe
  • Familiarity with the concepts of finite vs. infinite space
  • Basic knowledge of observational astronomy
  • Awareness of philosophical implications of "outside" the universe
NEXT STEPS
  • Research the implications of the universe's shape in cosmology
  • Study the concept of infinite vs. finite universes in theoretical physics
  • Explore the philosophical discussions surrounding the nature of space and existence
  • Learn about observational techniques in astronomy and their limitations
USEFUL FOR

Students of cosmology, philosophers interested in the nature of existence, and anyone curious about the fundamental properties of the universe.

A friend and I have been debating a topic for the last few days and I would really like a more informed opinion on the discussion.

My friend says that IF you could, some how, see the universe from the outside and it appears that the universe is a finite flat, spherical shape, or other shape then it obviously isn't infinite.

I say, because the universe is space itself, its apparent volume outside of space is irrelevant because it's not taking up any space. For all we know, it could look like a tiny sparkle to us on the outside and be the giant infinite universe we know on the inside. It may look finite on the outside but could never stop getting smaller.

Who is closer to correct, here? The information you give us is invaluable and highly treasured.

Your discussion has no scientific basis. It is unclear what you would even mean by "viewing the universe from outside". You cannot go outside the universe.

By definition there is no outside of the Universe.
