Discussion Overview

The discussion revolves around the concept of what contains the universe, exploring ideas of infinity, the nature of space, and the implications of the Big Bang. Participants engage with both philosophical and scientific perspectives, questioning the definitions and implications of a finite versus infinite universe.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Philosophical

Main Points Raised

  • Some participants question whether nothingness can be considered something and if the universe is infinite.
  • There is a debate about the nature of the Big Bang, with some suggesting it occurred everywhere rather than at a specific point.
  • Participants express difficulty in visualizing the universe's expansion and the concept of it expanding into nothing.
  • Some argue that if the universe is everything, it cannot be contained by anything, while others challenge this notion.
  • There are discussions about the implications of life arising from chemical reactions and whether matter possesses some form of intelligence.
  • Several participants explore the idea of finite versus infinite universes and the philosophical implications of boundaries and edges.
  • Some participants reference analogies, such as the balloon analogy, to explain the universe's expansion, while others critique the limitations of such analogies.
  • There is a suggestion that the universe could be finite yet still encompass everything, raising questions about the nature of boundaries.
  • Some participants propose the existence of other universes or an "ultra-universe," while others emphasize the lack of evidence for such claims.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the universe is finite or infinite, and multiple competing views remain regarding the implications of these concepts. There is ongoing debate about the nature of boundaries and containment.

Contextual Notes

Participants express uncertainty about visualizing complex concepts related to the universe's structure and expansion. The discussion includes various assumptions about definitions of finiteness and containment that are not universally agreed upon.

Its not because its everything there is FOR us that its everyrhing there is no? Are maths going to help me transcand the logic that something finite can't be everything there is? How do you picture it yourself?

There is no such logic. You are making it up out of whole cloth to fit your preconceived notions of how things must be.

The example of Earth's surface was a 2D example of what spatially is 3D in the universe: You can have a closed three dimensional, finite surface of a four dimensional manifold. Can I imagine it? No. Does math help to imagine it? Maybe, but at least it allows me to calculate with it, and this doesn't require imagination. I do not claim the universe to be the three dimensional surface of a four dimensional sphere, but it cannot be ruled out from the start. Cosmologists try to figure it out, but that's not an easy task, since manifolds aren't "embedded" in something. They are all there is: no outside!

Without further ado, I think the thread has run its course and that's its now time to close it. Thank you all for contributing here.

For @Spin2win please research the notions of infinity in math and physics and see if what you have learned in this thread helps you come to grips with what you now know.

Often in math and science, we must go back to the math to understand something and that's usually because it doesn't follow our commonsense or that we simply can't picture it in our minds. However, the math of a theory coupled with experiment is the ultimate arbiter of what is what in the universe as we understand it today.

Here's an article circa 2015 in Universe Today that attempts to describe our understanding of the vastness of the universe.
