In telegraph wire the electrons travel (as the disturbance) with the speed
of light.
The same is in the space. The disturbance always travel with the speed of
light.
Electrons and what you call "the disturbance' are completely different
things.
Nothing with a mass can travel at the speed of light.
Even in high vacuum tubes electrons travel much slower than the speed of
light
And this creates lots of problems.
Around an atom of hydrogen the electron travels at less than 1% of the
speed of light.
