I already said the photon has no anti-partilce. No the ether does not exist. An electromagnetic wave is the self sustaining interaction of the electric and magnetic fields via Maxwell's equations. Charge is not a virtual photon. A virtual photon is the mediating particle of the electromagnetic interaction.
Strong interactions have nothing to do with the absorption of electrons.
The photons anti photon is the photon. What are field lines. I already said the photon has no anti-partilce.
