The discussion centers on whether space can be considered materialistic or if it exists purely as a theoretical construct. Participants explore concepts from classical physics, general relativity, and quantum mechanics, noting that "empty" space is never truly empty and is filled with virtual particles and cosmic radiation. The analogy of space as a "fabric" is debated, with some arguing it confuses rather than clarifies the nature of gravity and curvature. It is concluded that while space exhibits properties like curvature, it does not necessarily imply it is a material substance. The conversation highlights the philosophical implications of space's nature, suggesting that current scientific consensus leans towards space being non-materialistic.

That's the Newtonian view of space. General relativity doesn't work that way; space isn't just a backdrop on which physics takes place.

I really really wish you hadnt said that. I now have to take my undertanding back to the drawing board so I hope you arent mistaken!
