The photon is the force carrier of the electromagnetic force, I'm not talking about photonics but hasn't the effect of every electric current dc or ac ever been due to photons acting only? In theory couldn't we have an electron-less current due to only photons but still with the same effects?

thank you for your reply

Just had a dream about someone that bowled a cricket ball (spin delivery) and after it bounced when it got to about a meter in height it just stopped dead in the air and hovered. What technology inside of the ball would be needed so that lift force was countered so that it would stop vertically...

I know that High-energy (hard) X-ray light cannot be focused as easily as visible light by using a burning glass. But why is this? If there was x ray light spread over a normal sized lens with the same intensity as sun light why couldn't it focus? would the material needed for say 50cm^2...

gelatin, celluloid paraffin and ivory all exhibit phosphorescence at lower temperatures why is that?

what equation is the energy of the em wave one that includes frequency and amplitude?

I know there are other things that fail about the rutherford atom but as the electron is accelerating and radiating away energy it would fall into the nucleus, my question is how much energy would the electron need to gain so that the classical atom could be stable a hydrogen atom for example

what about assuming negligible friction? and yes I am.

If two balls were close to each other in a pool of water and each had some angular momentum but one was spinning one way and the other was spinning the other way what would happen? same question for if they both were spinning the same way?

Isn't the reason the sky isn't bright at night ,due to all the stars, because the fact the stars aren't bright enough to be seen by the naked eye after a certain distance? So it doesn't necessarily depend on the fact the universe doesn't have to be infinite or expanding? I know the intensity of...

Does the cooper pairs spins (up and down) cancelling out have anything to do with anything? Is the current spin polarized in a superconductor?

cheers for replying as well

Why is the magnetic field of a superconductor normally excluded?

Sorry ignore the first question so again why does a superconductor have no magnetic field inside of it if electrically charged particles are moving.
