Discussion Overview

The discussion revolves around the potential coupling between space and matter and its implications for the expansion of the universe. Participants explore various perspectives on whether space possesses properties that interact with matter, particularly in the context of cosmic expansion.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant suggests that if space has a coupling to matter, the inhomogeneous nature of the universe could lead to larger volumes of space becoming free from gravity, potentially allowing for faster expansion.
  • Another participant introduces an analogy comparing the coupling of space and matter to water surface tension, proposing that a lack of matter (gravity) could decrease the "tension" of space.
  • A different viewpoint argues against the notion of space having properties that allow it to expand independently, stating that space does not have a separate existence and that its expansion is contingent upon the energy within it.
  • One participant posits that space and matter could be fundamentally linked, suggesting that space is merely an extension of matter, with their differences being a matter of degree of interaction.

Areas of Agreement / Disagreement

Participants express differing views on the nature of space and its relationship with matter, indicating that there is no consensus on whether space can be considered to have properties that affect its expansion.

Contextual Notes

Some arguments rely on assumptions about the nature of space and matter that remain unresolved, particularly regarding the definitions and implications of "coupling" and the properties attributed to space.

To start i have no idea if space has some (coupling) to matter,
but if it has--------
On the less than large scale our universe is inhomogonous, and
is getting more so with time (gravity is sweeping up matter into
clumps) so if there is some coupling between space and matter,
and matter is getting clumpified, then there will be less and less volumes
of space tied to matter/gravity ,therfore larger and larger volumes
of space are free from gravity, and free to do what it will (expand)
faster and faster.
This is not a theory just an observation, and i can see no reason
to guess that space free from gravity/matter will expand rather
than just stay as it was.
 
Space news on Phys.org
Ah, but it could be akin to water surface tension, when soap is
introduced, the soap, the ( lack of matter gravity), decreases
the surface tension.
 
You talk of space as if it were something? Something stretchy, mutable. There is no reason based on any current science of evidence to give space such properties. Sure we can 'curve' space with GR but this is just a mathematical way of describing the interactions between mass, it dosn't give space itself a separate existence and power.

If you talk of space expanding it can only do so because of what the energy within that space is doing. Space alone does not 'do' anything.
 
I like the idea that space and matter are one and the same. Space being merely the extension of matter. Matter being the foci of those extensions. The differences being no more than degree of interaction.
