+ spin Photons inside a right hand circularly polarized field with -spin photons outside of that field…”dark matter/energy”
As I understand it, If I am inside of a rh, circularly polarized EM field, there are only +spin photons inside the field: no -spin photons are admitted inside. The field inside serves to “filter” out -...
