Does the Medium Affect Gravitational Constant G?

Click For Summary
The gravitational constant "G" remains unchanged regardless of the medium it passes through, as any potential effects would be too weak to detect. Unlike light, which can be attenuated by materials like glass, gravity does not exhibit similar properties. While gravitational attraction can be influenced by the arrangement of mass, this does not equate to a reduction in gravity akin to dielectric polarization. The discussion clarifies that gravitational effects are fundamentally different from electromagnetic interactions. Overall, the medium does not affect the gravitational constant in any significant way.

why does the meduim does not affects gravitational constant "G"

I think you are asking about some sort of attenuation effect on gravity passing through a medium (like speed of light through glass)?

We wouldn't be able to tell if it did. It's incredibly weak so any effects would be virtually undetectable.
 
If you are comparing it to the dielectric susceptibility, then there is a similar effect of course. Gravitation will move objects so objects even further away will experience a modified attraction due to the rearrangement of objects.

But this is no negative gravitation, so you don't get the equivalent of the polarisation effect for dielectrics.
 
Thread 'What is the pressure of trapped air inside this tube?'
As you can see from the picture, i have an uneven U-shaped tube, sealed at the short end. I fill the tube with water and i seal it. So the short side is filled with water and the long side ends up containg water and trapped air. Now the tube is sealed on both sides and i turn it in such a way that the traped air moves at the short side. Are my claims about pressure in senarios A & B correct? What is the pressure for all points in senario C? (My question is basically coming from watching...
