SUMMARY

The discussion centers on the relationship between space expansion and mass presence, specifically questioning whether space contracts in high mass environments, such as within galaxies. It highlights the role of gravitons, theorized particles that convey gravitational force, and their relevance to the expansion of space. The conversation emphasizes that 'space' is defined as the emptiness separating matter, suggesting a complex interplay between mass and the fabric of space itself.

PREREQUISITES
  • Understanding of general relativity and its implications on space and mass.
  • Familiarity with the concept of gravitons and their theoretical role in physics.
  • Knowledge of cosmology, particularly regarding the expansion of the universe.
  • Basic grasp of particle physics and the nature of fundamental forces.
NEXT STEPS
  • Research the implications of general relativity on space-time curvature.
  • Explore the theoretical framework of gravitons and their significance in quantum gravity.
  • Investigate the effects of mass on space expansion in cosmological models.
  • Study the differences between gravitational interactions in low and high mass environments.
USEFUL FOR

Physicists, cosmologists, and students of theoretical physics interested in the dynamics of space, mass, and gravitational forces.

So, if space expands (measurements gets larger) in the presence of low mass, as between galaxies but not within galaxies, does space shrink in the presence of high mass (measurements between objects get smaller). So who needs gravitons?

Gravitons are the theorized particle responsible for carrying gravitational force. What do they have to do with expansion in any other way?
 


Let's not lose sight of the fact that 'space' is merely the emptiness that separates particles of matter.
