I don't quite understand your question. First, there is a big difference between voltage and resistance. Second, are there changes in the voltage of what, exactly? You only get Cherenkov radiation in electrically insulating materials.

Cherenkov radiation is when you get a particle (like an electron) to move faster than the speed of light in a certain material. Note that the speed of light is constant in vacuum, but varies when propagating through a material.

As a charged particle travels, it disrupts the local electromagnetic field in its medium. Sort of like how a skipped stone will leave waves in the water. Electrons in the atoms of the medium will be displaced by the passing EM field "ripple". Photons are emitted as the electrons restore themselves to equilibrium after the ripple has passed. These photons are radiation.

In normal circumstances, these photons destructively interfere with each other and no radiation is detected. However, when the disruption travels faster than the photons themselves travel, the photons constructively interfere resulting in radiation. This is what is called Cherenkov Radiation. It is analogous to the sonic boom created when an aircraft passes the sound barrier.

I have no idea how this relates to "anti-gravity".

Also one thing wery interasting that I would like you to comment - the compare Cherenkov radiation with the airplain bracking the sound bariere, but in this situation the wave is behind the plane, in Cherenkov light the wave is in front of the electron? How can that be? I have also explanation on this link

Concerning the article you refer to:

First, have you read the full article? I ask because a subscription to Physical Review B is expensive.

Second, the authors are not talking about Cherenkov radiation in the same context. (I have read the full article.) In their context, no particles are really moving at all, only a vortex. And if and only if that vortex exceeds the speed of sound (less than 350 m/s) in the superconductor will sound radiation (just like a sonic boom) be produced. You cannot produce Cherenkov light radiation in a superconductor. In fact, you cannot produce it in a simple metal.

If the electrical resistance dropped in a dielectric material such that you had a "voltage peak" as you describe, then you eliminate the actual physical mechanism by which Cherenkov radiation occurs. That is to say that your scenario is both physically and logically impossible.

compare Cherenkov radiation with the airplain bracking the sound bariere, but in this situation the wave is behind the plane, in Cherenkov light the wave is in front of the electron? How can that be?

Huh? Sound waves generated by a supersonic body do not move fast enough to get out of the way of the body itself, so the waves "stack up" and form a shock front, which is in front of the body itself. The same happens during a Cherenkov event, however in this case the wave is an electromagnetic field "ripple" as I discussed above. The actual light emission would occur after the electron passed.

Your statement is technically wrong for both supersonic bodies and Cherenkov radiation.

Wwll there may still be a way to test if electrons that create teh CHerenkov light make any changes in the electrical resistance. You can bombard one medium with high energy electrons that will produce Cherenkov light and measure the voltage and than do the same with electrons with energy just below the energy needet for Cherenkov light. This way you can see if this electron are making some tipe of resistance changes. In my theory this electrons have losed their mass (weight) and so they travel easyer thrue the medium reducing the electrical resistance. I would realy apreciate if you visit the aboule link to a discovery channel where I have this posts (pasting it here may take to much space - there are 3 pages) and explain to me why all of it is ridiciluos and to stop to belive in it.

Why light slows down when passing through matter should be explained. It is true that transparent objects are not absorbing light as it should be emitted at a different angle scattering any image.

The permitivity and permeability of the electromagnetic field of the atom is what slows down light.


Matter's EM field slows light. Its not soley absorption and reemesion. This means light speed can be changed for sure.

This needs to be addressed.

Why light slows down when passing through matter should be explained.

It is explained. We typically explain it in introductory physics courses. I even cover this in introductory courses for non-physics-majors.
