In what medium do light, energy, and matter exist?

Click For Summary

Discussion Overview

The discussion centers around the nature of light, energy, and matter, specifically questioning whether they exist in a medium similar to how sound travels through air or fish live in water. Participants explore theories related to the existence of a medium and the concept of absolute nothingness.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the existence of a medium for light, energy, and matter, suggesting a curiosity about various theories regarding their existence in the universe.
  • Another participant argues against the notion that spacetime must be classified as either a material or "nothing," emphasizing its geometric properties rather than material characteristics.
  • A similar point is reiterated by the same participant, highlighting the distinction between geometric properties of spacetime and material properties like velocity or density.
  • Another participant acknowledges the need for clarification, suggesting that some individuals may not have a clear understanding of these concepts and may seek answers.
  • A further response emphasizes that knowledge of something is derived from its properties, reiterating the geometric properties of spacetime mentioned earlier.

Areas of Agreement / Disagreement

Participants express differing views on the nature of spacetime and its classification, indicating that multiple competing perspectives remain without a consensus on the existence of a medium for light, energy, and matter.

Contextual Notes

Participants do not resolve the question of whether there is such a thing as absolute nothing, nor do they clarify the implications of spacetime's properties on the existence of a medium.

In what medium do light, energy, and matter exist?

I'm wondering what medium, material, substance do light, energy, and matter exist in. I'm not saying that I neccesarily think there is one, but I am wondering what the theories are in relation to our universe.
Do these three things exist in a medium like sound travels through air or fish live in water?

Is there actually such a thing as absolute nothing?

I don't know why people get the idea that spacetime must either be a material or "nothing". Spacetime has geometric properties such as distances (intervals), angles, and curvature. It does not have material properties such as velocity or density.

Well I figure some people don't know one way or another and might feel the need to ask those who do. I can't speak for people, but that is why I asked.
 
Fair enough. The point is that you only know what something is by the properties it has. In the case of spacetime it has the properties that I mentioned above.
