Thank you very much GO1.
So in the example I had the Poynting vector would be non zero. But that is not the case for all electric fields and all conditions. If either E or B are zero then you have no momentum.
GO1 do you use a tool for creating latex equations or are you just entering the codes?
Hypothetical question: If physics is ever unified, what journal would you expect the paper to first be published in?
Or in other words how do you think the world will first learn of it?
