Discussion Overview

The discussion revolves around the interaction between matter and space, specifically addressing how matter occupies space and the implications of this relationship. Participants explore theoretical perspectives, including classical and modern physics concepts, and consider the nature of space in relation to gravity and geometry.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions what happens to space when matter is nearby and whether space can be thought of as surrounding matter like a liquid.
  • Another participant suggests that there are multiple answers to the question, citing Newton's and Einstein's theories as useful in different contexts.
  • Some participants propose that space may be understood as geometry, with distances between point masses representing spatial relationships.
  • There is a challenge to the geometric view, referencing general relativity's assertion that gravity warps space.
  • One participant draws a parallel between the discussion and historical concepts of ether, suggesting that ether matter fills the universe and allows for the propagation of light and forces.
  • Another participant agrees that space as geometry is insufficient to explain general relativity, emphasizing that near matter, the geometry of space is curved.

Areas of Agreement / Disagreement

Participants express differing views on the nature of space and its relationship with matter, with no consensus reached on a singular explanation. The discussion includes competing models and interpretations, particularly regarding the implications of general relativity.

Contextual Notes

The discussion reflects a variety of assumptions about the nature of space and matter, including the dependence on different physical theories and the unresolved implications of general relativity. The relationship between geometry and gravity remains a point of contention.

My question is quite simple really. What happens to space when matter comes into it's vicinity? How is it, that matter can occupy one area of space, and then move into another area?

Is it practical to think of space as "surrounding" and object like a liquid does a solid object?

It may be a simple question, but the answer(s) are not so simple. As with most things in science there is not a single answer, but rather a wide variety of answers that are useful in different circumstances. Newton's ideas on the subject are quite useful in some circumstances, Mach and Einstein's ideas are more accurate in other circumstances.

Personally I think space is just geometry, e.g. two point masses have a geometrical relation with each other which is known as distance, space is that geometrical relationship
 
Perhaps space is nothing more than geometry, but that doesn't account for the general theory of relativity, which states gravity warps space.
 
Your thinking resembles the idea of ether matter from the beginning of 20 century. As I was told, this kind of ether matter fills the whole universe, thus light, forces etc... can propagate through the space.

Sure it does. Near matter the geometry of the universe is simply curved: triangles have more than 180º, initially parallel lines eventually intersect, etc.
