Discussion Overview

The discussion centers on whether the gravitational force between two bodies depends on the medium between them and the question of whether gravitational force is quantized. The scope includes theoretical considerations and conceptual clarifications regarding gravity and its properties.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions if the gravitational force is influenced by the medium separating two bodies, suggesting that the curvature of space-time varies in different media, such as vacuum versus water.
  • Another participant emphasizes that referring to gravitation as a force is misleading, proposing that it is better understood as a curvature in space-time.
  • It is noted that all materials have a gravitational effect, and factors such as energy, pressure, momentum density, and radiation also contribute to gravitational interactions.
  • The concept of the graviton as the theoretical carrier of quantized gravity is introduced, with the acknowledgment that it has not been experimentally observed and that a complete theory of quantum gravity is still under development.

Areas of Agreement / Disagreement

Participants express differing views on the nature of gravitational force and its dependence on medium, with no consensus reached on these questions. The discussion remains unresolved regarding the quantization of gravity.

Contextual Notes

Participants reference the theoretical aspects of gravity and its quantization, but there are limitations in terms of experimental evidence for concepts like the graviton and the implications of medium on gravitational force.

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...
