if this is true, than einsteins theory s wrong. one or the other, or supprise me.

No Einstien was pretty close infact electron flow is real close to light speed in atmosphere. In fact light travels a bit faster in the vacuum of space but electrons encounter much more friction then the tiny photons of light so it is a bit slower. Not so much that you would recognize it though

Electricity travel s MUCH slower than light.
The elelctrons in a current carrying wire actually only move at a few centimetres per second - you could walk faster than them
However, the impulse in the wire travels faster (if you push an electron at one end, it does not have to travel the whole length of the wire to affect the other end, it just has to push the next electron and so on until a different electron pops out the other end).
The speed at whcih impulses travel down wires is governed by Maxwells equations - and in particular special solutions called the waveguide equations. It depends on the type and size of wire. This is why we use coaxial cable or twisted pairs when we want to send high frequency signals.

First of all,.. NO, electricity does NOT "move faster" that light.
I would think that if you understood Einstein's theories to the point of being able to declare them "wrong", then you would quickly deduce, if not already know that light travels faster than electricity.
I'm not knocking you,... 'just get your answers before making your declarations!

Does it really? I did not know! So is with the world!! Nominate the person who discovered that electricity travels faster than light to Nobel Prize in Physics.

@justme
Totally wrong; the speed of electric current is dependent upon the medium of transfer. Electricity travels fast enough for us not to notice it every day. It travels roughly 1/3 as fast as light in copper wires.

Electricity travels at the same speed as light

Nothing travels faster than light.

It's a little slower than light.
