    Bend Space
Click For Summary

Discussion Overview

The discussion explores the concept of bending space, using a metaphor of folding paper to illustrate ideas about dimensionality and the universe. Participants examine the implications of infinite folding and the limitations of physical properties in both paper and space.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant proposes the idea of bending paper and space infinitely, questioning whether space can be manipulated in a similar manner to paper.
  • Another participant points out that paper has finite thickness, which limits the number of folds, while 2D space has zero thickness, allowing for hypothetical infinite layering.
  • A participant asks for clarification on the metaphor of the universe as a wrapped-out paper and what it aims to explain.
  • Another participant suggests that the metaphor does not provide a clear explanation of the universe's structure.
  • One participant encourages familiarity with current cosmological models to better inform future questions.

Areas of Agreement / Disagreement

Participants express differing views on the utility and clarity of the paper metaphor for explaining the universe, with some questioning its effectiveness while others explore its implications. The discussion remains unresolved regarding the metaphor's explanatory power.

Contextual Notes

Limitations include the lack of consensus on the metaphor's validity and the assumptions about dimensionality and physical properties of space versus paper.

So today i decided to start bending my paper few time. Bending my dots i draw on paper. Also i want to bend it infinite times. Can I bend space infinite times all until the space becomes one dot.

Illustration :)

This is my paper and i draw 2 dots on them.

After I bent i draw one more.

And i bent them again.

Assume i can bend them infinite times it will change into infinite long stick?
Can we do that with a space also?

A couple of ways to address this.

In the case of the paper, it has a finite thickness, so folding it more than a certain number of times will be problematic.
In the case of 2D space, it has zero thickness, so yes you can (hypothetically) layer it infinite times, but it will never gain any thickness.

Can you also tell me why we can't explain Universe as a wrapped-out paper metaphore?

What does the metaphor explain?
 
From single point we have wide Universe space (started unwrapping).
 
Well, that's not really an explanation.
 
3301, I recommend taking some time to get familiar with our best current model of the universe in cosmology. It will help you to focus future questions. Ned Wright's cosmology FAQ and tutorial are a good start:

In the meantime, this thread is closed.
