SUMMARY

The discussion centers on the nature of gravitational force and its dependence on the medium between two bodies. Participants clarify that gravitation is not a force but rather a curvature in space-time, which varies in different mediums such as vacuum and water. The concept of quantized gravity is introduced, with the graviton proposed as its theoretical carrier, although it has yet to be observed experimentally. The conversation emphasizes the ongoing exploration of gravity's role in quantum mechanics and the need for further research in this area.

PREREQUISITES
  • Understanding of general relativity and space-time curvature
  • Familiarity with quantum mechanics concepts
  • Knowledge of gravitational radiation theory
  • Basic principles of particle physics, particularly the graviton
NEXT STEPS
  • Research "gravitational radiation theory" as outlined by F.A.E. Pirani
  • Study the implications of "quantum gravity" and its current theoretical frameworks
  • Explore the concept of "gravitons" and their role in particle physics
  • Investigate the effects of different mediums on gravitational interactions
USEFUL FOR

Physicists, researchers in gravitational theory, students of quantum mechanics, and anyone interested in the intersection of gravity and quantum physics.

Is the Gravitational force between the two bodies depend upon the medium between them?and is the gravitaional force is quantized?

Do you have access to a good university library?

"Survey of gravitational radiation theory," F.A.E. Pirani, in Recent Developments in General Relativity, Pergamon, 1962, p. 89.
 
i havn't.but i will search this book on internet.
thanks
 
I would like to point out that referring to gravitation as a force is not quite correct. Gravitation is not a force it is a curvature in space-time.

A possible answer to your question is this: the curvature of space-time is different in vacuum than in watter for example because watter has mass and contributes to the overall curvature.
 
post 4 seems good...no material known "blocks" gravity...and all material has a gravitational effect...so does energy, pressure, momentum density,radiation,etc...

The theoretical carrier of quantized gravity is the graviton...never observed experimentally...gravity might someday be included in an overall theory of quantized gravity...called quantum gravity...not yet complete...
