SUMMARY

The discussion centers on the nature of space and its materialistic properties, questioning whether space itself can be considered an object or substance. Participants clarify that while classical physics treats space as empty, General Relativity and Quantum Mechanics introduce complexities, suggesting that space is never truly empty and is influenced by the presence of matter. The Michelson-Morley experiment is cited as evidence against the notion of a fabric of space, reinforcing the idea that space does not possess material properties. Ultimately, the consensus leans towards the view that space itself is not materialistic, but rather a framework for understanding the relationships between physical objects.

PREREQUISITES
  • Understanding of General Relativity and its implications on spacetime curvature
  • Familiarity with Quantum Mechanics and the concept of virtual particles
  • Knowledge of classical physics principles regarding space and gravity
  • Awareness of the Michelson-Morley experiment and its significance in physics
NEXT STEPS
  • Research the implications of General Relativity on the nature of spacetime
  • Explore Quantum Field Theory and its perspective on "empty" space
  • Investigate the philosophical debates surrounding the nature of space and materialism
  • Examine the results and impact of the Michelson-Morley experiment on modern physics
USEFUL FOR

Physicists, philosophers of science, and students of theoretical physics seeking to understand the complexities of space, gravity, and the materialistic versus non-materialistic interpretations of the universe.

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!
