Capacitors block DC voltage. AC signals appear to pass through
capacitors,
but they don't actually do that.

Correct.

It's simple electrostatics.

An electron arriving on one plate of (assumed vacuum dielectric)
will repel another from the opposite plate.

An electron pulled off one plate will attract an electron onto
the other.

Pulling and pushing in this way is the essence of AC.

The current doesn't actually flow through, but because the net effect on
both
sides is the same, the current appears to flow through!
