Gravitation and refraction.

[Гера�им]

 

Action of gravitation reminds me light refraction in transparent substances.For example,violet beams refract in glass more strongly red,we will present index of refrection increases, beams will stsrt being bent as in a cycloid.Action of gravitation is similar, but it is more difficult,it is necessary to consider the particles creating the weight which sticks at the movement of particles and the and the final result the Solar system and galaxy will turn out.Of course space not empty,space particles the which create gravitation at the movement are involved in the movement.Also,between magnetism and gravitation similarity is found, at a piece of a magnet the movement of its atoms coordinated therefore also action is stronger than at an obyny piece.

Could be a post from the first millennium BCE. I couldn't make out the physics in it. Seems archaic.

Maybe. But ...

 

For example,violet beams refract in glass more strongly red

 

That is not the case for gravitational lensing. All frequencies are affected equally.

 

Also,between magnetism and gravitation similarity is found

 

But also many more differences. (Your comments are so vague and confused, there isn't much more to say.)

Just as an interesting passing comment, when you pass to QED on a curved space-time you do get dispersion.

That is interesting. Is there somewhere I can read a (simple) description of that?

Prof. Shore was my MPhys project supervisor 15 years ago or so.

Awesome. I've never seen any articles on this before.

Thanks. Only slightly ( ) over my head!

Intetesting paper. Not sure I agree with the superluminal light aspects. They do show how it can occur without violating causality but I'm still studying it. However some of the metrics in it are handy irregardless. Thanks for posting it

Shore and Hollowood address this in a series of papers. I can't remember exactly now what conclusion was, but causality can be preserved as can some other expected aspects of quantum field theory.

I'll have to look them up could be intersting reading
