Discussion Overview

The discussion revolves around the concept of the smallest possible volume in three-dimensional space, exploring the implications of quantization versus continuity in space and time. Participants examine theoretical frameworks and models related to these ideas, including references to Planck distance and dimensional relationships.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that there may be a minimum volume, distance, area, or time, while others argue for the continuity of space and time.
  • There is mention of the Planck distance as a potential shortest distance, though specifics are not provided.
  • Questions are raised about the minimum locations required for a volume to exist and the relationship between 2-dimensional and 3-dimensional spaces.
  • One participant discusses the concept of compactifying a 3-dimensional volume and the implications of dimensional transposition in brane models.
  • Another viewpoint suggests that if spacetime is quantized, there are limits to how much one can "zoom in," whereas a continuous perspective allows for infinite subdivision of space and time.

Areas of Agreement / Disagreement

Participants express differing views on whether space and time are quantized or continuous, indicating that multiple competing perspectives remain without consensus.

Contextual Notes

The discussion includes unresolved assumptions about the nature of space and time, as well as the implications of dimensionality in theoretical models. Specific mathematical or physical definitions are not fully explored.

Who May Find This Useful

This discussion may be of interest to those exploring theoretical physics, particularly in the realms of quantum gravity, dimensional theories, and the foundations of spacetime. Readers interested in the implications of quantization versus continuity in physics may also find value in this exchange.

And what are the minimum locations needed for a Volume to exist?
 
Physics news on Phys.org
Olias, I think this is still controversial, some people think there is a minimum volume, distance, area, time, etc. while others think space and time are probably continuous. (Penrose?)(String theorists?)
Those who believe in quantized space talk about the Planck distance as the shortest distance possible. I don't remember the exact number as a fraction of a meter for the Planck distance but it is very, very small. (you can look it up in google)
If you are interested in these topics, you may also do a Google search on "quantum loop gravity".
There are some recent popularizations which you can probably find at your local Barnes and Nobles. Look for authors like Greene and Smolin.
Good luck, and let us know what you found.

And what is the smallest bit of 2-Dimensional Space that can exist within an area that is Bounded by 3-Dimensions?

Actually does a 2-D space have to be Smaller than 3-D space?..does Quantizizing(sorry about spelling) of 3-D, actually reveal that 2-D must exist within a volume of 3-Dimensional Volume?

If one compactifies a Volume of 3-D space, then at a certain limit a 2-Dimensional Volume can encompass the 3-D volume, one can actually make the statement that a discrete 3-D can be surrounded by an infinite 2-D volume, I know that some Brane models are using a sort of Dimensional transposition, where embbeded Branes inter-mingle, but what if higher and lower branes collide, what is the outcome of such things..if at all they are possible.
 
If you believe that spacetime (this includes space and time) is quantised, then there are definite limits as to how far we can "zoom in" since after a certain point space and time will be playing with each other.

If you think spacetime is continuous as did Newton and Einstein, then you can go zooming in forever and forever and forever. For any two points with a small distance (or any two moments) there is another point (or moment) in between.
