Just curious, how is the electric field transmitted through a vacuum?

The electrical field does not need a vacuum. Like the nucleus on an atom, does not need anything to attract the electrons around it.

There are theories about some things that might carry fields. We see many of those in Quantum Electro Dynamics (QED), where virtual particles are transferring forces. They even describe the Higgs field, which transfers some mass. The problem is that virtual particles do not really exist, so scientists try to work with fields instead of particles.

There are also theories about quantum foam and even superstrings. Older theories have ideas about some kind of aether, but the popular ones have problems with explaining relativity. The mainstream theories include relativity by adding other dimensions and complex mathematical transformations.
